Lens Luxation

Lens luxation in rabbits refers to the displacement of the crystalline lens from its normal position within the eye due to weakening or rupture of the zonular fibers that hold it in place. Under normal circumstances, the lens is suspended directly behind the pupil by delicate fibers called zonules that connect it to the ciliary body, allowing it to remain centered in the visual axis and properly focus light onto the retina. When these supporting structures fail, the lens may move partially out of position, termed subluxation, or completely dislocate into either the anterior chamber in front of the iris or the posterior segment behind where it normally sits. This displacement has significant implications for both vision and eye health, potentially causing pain, inflammation, glaucoma, and permanent vision loss.

The pathophysiology of lens luxation involves progressive weakening and eventual rupture of the zonular fibers. In rabbits, this most commonly occurs secondary to other ocular diseases rather than as a primary inherited condition. Chronic glaucoma causes stretching and thinning of the zonules as the eye enlarges, eventually leading to lens displacement. E. cuniculi infection can weaken zonular attachments through direct parasitic damage or secondary inflammation. Cataracts, particularly those associated with E. cuniculi, may cause lens swelling that stresses the zonules. Trauma can acutely rupture zonules, causing sudden lens displacement. Chronic uveitis from any cause damages zonular integrity over time. Once zonular degeneration begins, progression is typically inevitable, though the timeline varies considerably.

The impact of lens luxation on rabbit health depends significantly on the direction of displacement and the presence of associated complications. Anterior lens luxation, where the lens moves forward into the anterior chamber in front of the iris, represents an ophthalmic emergency. The displaced lens can physically block aqueous humor drainage, causing rapid, severe pressure elevation that threatens both vision and eye comfort. Contact between the lens and cornea causes corneal edema and potentially ulceration. Posterior lens luxation, where the lens falls back into the vitreous cavity, is generally less immediately threatening but can still cause visual impairment and ongoing inflammation. Subluxation, with the lens remaining partially attached but off-center, may cause minimal symptoms or progress to complete luxation over time.

Treatment of lens luxation in rabbits varies based on the type of displacement, presence of complications, and visual status of the affected eye. Anterior lens luxation typically requires urgent surgical removal to relieve pupillary block and prevent corneal damage. Posterior lens luxation may be managed medically in some cases, particularly if vision is already compromised and the eye is comfortable. Subluxation often warrants monitoring with medical management of any associated uveitis and glaucoma risk. The prognosis depends on the underlying cause, duration before treatment, and development of secondary complications. Early recognition and prompt intervention provide the best outcomes, but the underlying conditions that cause lens luxation in rabbits often limit overall visual prognosis. Care should be provided by a rabbit-savvy veterinarian with referral to a veterinary ophthalmologist strongly recommended for surgical cases.

Secondary lens luxation due to chronic ocular disease represents the most common cause in pet rabbits, with glaucoma being a particularly significant predisposing factor. As intraocular pressure rises in glaucomatous eyes, the globe stretches and enlarges, placing progressive stress on the delicate zonular fibers. Eventually these fibers fail, allowing the lens to dislocate. The relationship between glaucoma and lens luxation is bidirectional, as lens luxation can also cause or worsen glaucoma by obstructing aqueous drainage, creating a challenging cycle of disease progression. Buphthalmic eyes from chronic uncontrolled glaucoma are at highest risk, but lens luxation can occur even with moderate pressure elevation over sufficient time.

E. cuniculi infection contributes to lens luxation through multiple mechanisms. This common microsporidian parasite has particular affinity for lens tissue and can directly damage the lens capsule and adjacent structures including zonular attachments. The inflammatory response to E. cuniculi infection causes additional tissue damage. Cataracts associated with E. cuniculi may swell, placing mechanical stress on zonules. When E. cuniculi causes lens rupture, the loss of lens integrity destabilizes the entire structure. Phacoclastic uveitis following lens rupture creates intense inflammation that further damages zonules. Given the prevalence of E. cuniculi in rabbit populations, this parasite represents a major contributor to lens luxation in pet rabbits.

Trauma can cause acute lens luxation through direct mechanical disruption of zonular fibers. Blunt trauma to the head or eye, such as from falls, kicks, or collisions, may generate sufficient force to rupture zonules. Penetrating injuries can directly damage zonular attachments. Fight injuries between incompatible rabbits may cause ocular trauma leading to lens displacement. Even relatively minor trauma may cause subluxation that progresses to complete luxation over time as remaining weakened zonules fail. The history of trauma may be clear or may have occurred without the owner's knowledge, making traumatic etiology sometimes difficult to confirm.

Chronic uveitis from any cause progressively damages zonular fibers through inflammatory mechanisms. Bacterial uveitis, often secondary to dental disease that spreads to affect the eye, creates ongoing inflammation that weakens zonular attachments. Immune-mediated uveitis, though less common in rabbits than some species, can have similar effects. Lens-induced uveitis from cataracts of any cause damages surrounding structures. The duration and severity of inflammation correlates with zonular damage, with prolonged or repeated episodes of uveitis increasing luxation risk. Any rabbit with chronic ocular inflammation should be monitored for signs of lens instability.

Unlike dogs and some other species where primary inherited lens luxation is well-documented, rabbits do not appear to have a recognized hereditary form of primary lens luxation. The condition in rabbits is almost always secondary to other disease processes. However, genetic factors influencing susceptibility to predisposing conditions such as glaucoma or E. cuniculi disease manifestations might indirectly affect lens luxation risk. Age-related zonular degeneration likely occurs to some degree, potentially contributing to lens instability in geriatric rabbits, though this has not been extensively studied. Other rare causes include intraocular neoplasia affecting zonular structures and complications of intraocular surgery.

Early warning signs of lens luxation may be subtle, particularly in cases of gradual zonular weakening preceding complete displacement. Because rabbits instinctively hide signs of illness and discomfort, early lens instability often goes unnoticed. Owners may observe subtle changes in the appearance of the eye, such as the pupil seeming slightly off-center or irregularly shaped. The lens may appear to shimmer or wobble slightly when the rabbit moves its head, a finding called phacodonesis that indicates zonular weakness. Iridodonesis, a trembling of the iris, may also be visible as the lens no longer provides stable support. These subtle signs are often only detectable during careful examination and may be missed on casual observation.

Acute anterior lens luxation produces dramatic and usually obvious clinical signs. The lens, normally hidden behind the pupil, becomes visible in the anterior chamber as a clear or opaque structure in front of the iris. The pupil may appear abnormally shaped or displaced as the iris is pushed aside by the dislocated lens. The cornea often develops edema at the point where the lens contacts it, appearing cloudy or blue-gray. The eye typically appears red and inflamed, and the rabbit may squint or hold the eye closed due to pain. This condition is extremely painful due to both direct tissue irritation and rapidly rising intraocular pressure from blocked aqueous drainage.

Posterior lens luxation and subluxation produce less dramatic signs that may easily be overlooked. When the lens falls posteriorly into the vitreous, it may not be visible without special equipment, and external examination may appear relatively normal. The anterior chamber may appear deeper than normal due to the lens no longer filling its usual space. Visual impairment occurs but may not be obvious given rabbits' ability to compensate with their remaining vision. Subluxation may cause minimal external changes, with the diagnosis made during detailed ophthalmic examination showing the lens tilted or decentered from its normal position.

Behavioral changes associated with lens luxation reflect both visual impairment and pain when present. Rabbits with anterior luxation often show obvious signs of distress, including decreased activity, reluctance to eat, hiding behavior, and teeth grinding indicating pain. Those with posterior luxation or subluxation may show subtler changes such as altered navigation, decreased confidence when moving, or reduced responsiveness to visual stimuli. Any reduction in appetite is particularly concerning in rabbits and must be addressed promptly to prevent GI stasis. Changes in social behavior, including withdrawal from companions or increased dependence on bonded partners for navigation, may be noted.

Physical examination findings vary with the type and severity of lens luxation. Anterior luxation is typically obvious on direct inspection, with the lens visible in the anterior chamber. Tonometry reveals elevated intraocular pressure in most acute anterior luxations. Examination may show aphakic crescent, a dark region visible through the pupil where the lens is no longer present. In posterior luxation, the lens may be visible floating in the vitreous using an ophthalmoscope. Signs of underlying disease such as glaucoma-related buphthalmos, E. cuniculi-associated cataracts, or evidence of trauma may be present. Both eyes should be evaluated as the predisposing condition often affects both, and the fellow eye may show early zonular instability.

Emergency symptoms requiring immediate veterinary attention include sudden onset of severe eye pain manifested by squinting, teeth grinding, and refusal to eat, visible lens in the anterior chamber, sudden changes in the eye's appearance or size, or rapid worsening of any previously stable condition. Anterior lens luxation is a true emergency that can cause permanent vision loss within hours to days if not addressed. A rabbit that stops eating for more than 12 hours faces life-threatening GI stasis and requires emergency care. Any rabbit with obvious ocular distress should be evaluated urgently rather than waiting for a routine appointment.

Diagnosis of lens luxation begins with comprehensive ophthalmic examination by a veterinarian, ideally a veterinary ophthalmologist. Visual inspection may reveal gross abnormalities such as anterior lens luxation, where the dislocated lens is directly visible in the anterior chamber. Slit lamp biomicroscopy provides detailed evaluation of the anterior segment, allowing visualization of the lens position, any remaining zonular attachments, and the relationship between the lens and surrounding structures. The presence of phacodonesis and iridodonesis, trembling of the lens and iris respectively, indicates zonular weakness even before complete luxation occurs. The character of the dislocated lens, including whether it is clear or cataractous, provides information about underlying cause.

Tonometry is essential in evaluating any rabbit with lens luxation or suspected zonular instability. Intraocular pressure measurement identifies secondary glaucoma, which commonly accompanies anterior lens luxation and can also be a predisposing factor for luxation. Elevated pressure requires immediate management regardless of treatment decisions about the luxated lens. Serial pressure measurements may be needed to track the condition and assess treatment response. Normal pressure does not exclude significant disease, and posterior luxation may occur without pressure elevation.

Ocular ultrasound helps characterize lens position when direct visualization is limited and evaluates for concurrent pathology. This imaging modality clearly shows the lens location, including posterior luxation that may not be visible ophthalmoscopically. Ultrasound can detect vitreous changes, retinal detachment, and other posterior segment abnormalities that affect prognosis and treatment decisions. The examination also helps assess the fellow eye for early zonular instability or underlying disease. This non-invasive imaging is generally well-tolerated by rabbits and provides valuable information for surgical planning when intervention is being considered.

Determining the underlying cause of lens luxation guides treatment and prognosis. E. cuniculi serology is indicated in most cases given the frequency of this parasite in rabbit ocular disease. History and examination findings may suggest traumatic etiology. Evidence of glaucoma as either cause or effect of the luxation should be thoroughly evaluated. Examination for dental disease may reveal a source of chronic ocular inflammation. Systemic evaluation ensures any underlying health issues are identified. The underlying cause significantly affects prognosis and the likelihood of the fellow eye developing similar problems.

Differential diagnosis for abnormal lens appearance includes cataracts, which may be present concurrently with luxation but represent lens opacity rather than displacement. Lens coloboma, a congenital notch in the lens, may cause abnormal appearance but without displacement. Posterior synechiae, adhesions between the iris and lens, can make the pupil appear abnormal but the lens remains in position. Spherophakia, an abnormally round lens, may mimic subluxation. In some cases of complete posterior luxation, the lens may not be visible at all, and the condition may be confused with aphakia, the absence of a lens. Careful examination differentiates these conditions and identifies lens luxation accurately.

Emergency treatment for anterior lens luxation focuses on reducing intraocular pressure and managing pain while preparing for definitive intervention. Medical pressure reduction using topical and potentially systemic agents is initiated immediately, though anterior luxation often cannot be controlled medically long-term due to the physical obstruction caused by the displaced lens. Mydriatic agents may be attempted to dilate the pupil sufficiently to allow the lens to fall posteriorly, converting an anterior luxation to the less urgent posterior form. This maneuver is not always successful but can buy time and reduce the urgency of surgical intervention when it works. Pain management with systemic analgesics such as meloxicam provides comfort while awaiting definitive treatment. Any reduction in appetite must be addressed immediately with supportive feeding to prevent GI stasis.

Surgical lens removal through intracapsular lens extraction represents the definitive treatment for anterior lens luxation and is strongly recommended in most cases. This procedure, performed by a veterinary ophthalmologist, involves removing the entire lens through a large corneal or scleral incision. The surgery requires general anesthesia, which in rabbits must be performed by an experienced team familiar with rabbit-specific considerations, including the absolute prohibition on pre-anesthetic fasting that applies to other species. Success rates are generally good when surgery is performed promptly, though complications including continued glaucoma, corneal scarring, and retinal detachment can occur. Post-operative care is intensive, requiring frequent medication administration and close monitoring.

Medical management may be appropriate for posterior lens luxation and some cases of subluxation. When the lens has fallen posteriorly and is not causing immediate problems, medical therapy focuses on controlling inflammation with topical anti-inflammatory medications and monitoring for secondary glaucoma. Miotics, medications that constrict the pupil, may help prevent a posteriorly luxated lens from moving forward. E. cuniculi treatment with fenbendazole is indicated when this parasite is suspected or confirmed. Regular monitoring tracks for disease progression, and surgical intervention may be recommended if complications develop. This approach is particularly appropriate when vision is already compromised and the primary goal is maintaining eye comfort.

Enucleation, surgical removal of the eye, may be recommended when the eye is blind and painful, when surgery is not accessible or affordable, or when the underlying disease process makes lens removal unlikely to preserve useful vision. Rabbits adapt remarkably well to life with one eye, and quality of life often improves dramatically when a painful, non-functional eye is removed. The procedure is less complex than lens extraction and may be performed by experienced general practitioners familiar with rabbit anesthesia. Recovery is typically straightforward, with most rabbits returning to normal activity within one to two weeks.

Supportive care throughout treatment addresses overall health and prevents secondary complications. Pain management ensures comfort and helps maintain appetite. Nutritional support with syringe feeding prevents GI stasis if food intake decreases. The eye may need protection from self-trauma, though any protective devices must be modified to allow cecotrophy, as rabbits must eat their cecotropes for proper nutrition. Activity restriction may be recommended during recovery from procedures. Monitoring the fellow eye for early signs of zonular instability allows proactive management if bilateral disease develops.

Treatment decisions must weigh multiple factors including visual potential of the affected eye, presence of painful complications, underlying cause, owner resources, and practicality of aftercare. Anterior luxation generally requires surgical intervention for comfort if not for vision. Posterior luxation offers more flexibility in management approach. The condition of the fellow eye influences decisions, as bilateral disease may require staged or prioritized treatment. Quality of life must remain the primary consideration, with treatment goals clearly defined and realistic expectations established through communication with the veterinary team.

Recovery timeline following lens extraction surgery involves several weeks of intensive care followed by gradual return to normal activity. The immediate post-operative period requires frequent medication administration, typically including topical antibiotics, anti-inflammatory medications, and pressure-lowering drops. The first few days after surgery require close monitoring for complications including hemorrhage, severe inflammation, or infection. The surgical incision heals over approximately two to four weeks, during which medications are gradually reduced. Visual recovery, when it occurs, may be apparent within days of surgery, though focusing ability is compromised without a lens. Full recovery takes four to six weeks in uncomplicated cases, though ongoing monitoring continues longer.

Post-operative care following lens extraction is demanding and requires committed owners. Topical medications must be administered multiple times daily, typically for several weeks. Protection from self-trauma using modified recovery collars or other methods may be necessary, with careful attention to ensuring the rabbit can still eat cecotropes. Activity restriction prevents excessive stress on healing tissues. Appetite must be monitored carefully, with syringe feeding initiated if food intake decreases. Follow-up examinations, initially frequent and then at decreasing intervals, monitor healing, intraocular pressure, and any complications. Adherence to the treatment protocol significantly affects outcomes.

Prognosis following lens luxation treatment depends on the type of luxation, underlying cause, duration before treatment, and development of complications. Anterior lens luxation treated promptly with surgery has reasonable prognosis for preserving a comfortable, potentially sighted eye. Delayed treatment or complications worsen outcomes significantly. Posterior lens luxation managed medically often maintains a comfortable eye, though vision is typically compromised. Eyes with severe underlying disease such as advanced glaucoma or extensive E. cuniculi damage have guarded prognosis regardless of treatment approach. Enucleation, when indicated, has excellent prognosis for comfort and quality of life.

Long-term outlook following lens luxation requires ongoing monitoring and management of any underlying conditions. Eyes that have undergone lens extraction need periodic evaluation for secondary glaucoma, retinal changes, and other complications. Medical management of posterior luxation requires continued vigilance for progression to anterior luxation or development of complications. The fellow eye should be monitored for development of similar problems, particularly when the underlying cause affects both eyes. E. cuniculi-positive rabbits require systemic management and monitoring for disease in other organs. With appropriate care, many rabbits with lens luxation, including those who have lost one eye to the condition, can maintain excellent quality of life for their normal lifespan.

Prevention of secondary lens luxation focuses on managing conditions that predispose to zonular degeneration. Appropriate treatment of glaucoma, including diligent medication administration and regular pressure monitoring, may slow or prevent the globe enlargement that stresses zonular fibers. Early intervention when glaucoma is detected provides the best chance of preserving zonular integrity. When glaucoma cannot be adequately controlled medically, surgical interventions should be considered before extensive damage occurs. Monitoring eyes with known glaucoma for signs of zonular instability allows proactive management.

Management of E. cuniculi reduces the risk of ocular complications including lens luxation. Treatment with fenbendazole when infection is identified may help prevent progression of lens disease. Appropriate management of E. cuniculi cataracts and uveitis reduces the inflammatory damage that weakens zonules. Monitoring E. cuniculi-affected eyes for early signs of zonular instability enables early intervention. While E. cuniculi cannot always be prevented, reducing exposure through good husbandry practices and managing stress to support immune function may reduce disease severity.

Prevention of traumatic lens luxation involves creating safe environments and minimizing injury risk. Housing should be free of hazards that could cause falls or collisions. Rabbits should be properly introduced before cohabitation to prevent fight injuries. Supervision during exercise time prevents accidents. Protection from other household pets reduces trauma risk. Careful handling prevents accidental drops or injuries. While trauma cannot be entirely prevented, reducing risk factors decreases the likelihood of traumatic lens luxation.

Maintaining overall ocular health supports zonular integrity. Prompt treatment of any uveitis reduces the duration of inflammation that damages zonular fibers. Regular veterinary examinations including comprehensive eye assessment allow early detection of conditions that might predispose to luxation. Dental health maintenance prevents infections that can spread to affect the eye. Good nutrition and appropriate housing support general health and immune function. Establishing a relationship with a rabbit-savvy veterinarian ensures appropriate care is available when needed.

Early intervention when signs of zonular instability are detected may prevent or delay complete lens luxation. Phacodonesis and iridodonesis, trembling of the lens and iris, indicate weakening zonules and warrant heightened monitoring. Medical management to control any underlying inflammation or pressure may slow progression. Surgical lens removal may be considered prophylactically in eyes with severe zonular compromise before complications develop, though this decision must weigh surgical risks against the likelihood and timeline of progression. Close monitoring allows intervention at the optimal time.

Daily management of a rabbit recovering from lens luxation treatment or living with medically managed luxation requires consistent attention to medications, monitoring, and overall care. Medication schedules must be followed carefully, with topical medications administered using proper technique to ensure efficacy. Oral medications should be given at consistent times and may be mixed with a small amount of food if needed. Daily observation of the affected eye monitors for changes that might indicate complications or progression. Food intake and fecal output tracking provides early warning of any developing problems. Any concerning changes should prompt veterinary consultation rather than waiting for scheduled appointments.

Home environment modifications support safety and quality of life for rabbits with vision impairment from lens luxation. Consistent placement of furniture, food, water, and litter boxes helps rabbits navigate using memory. Removing sharp edges, blocking access to stairs or elevated surfaces, and providing non-slip flooring reduces injury risk. Quiet, low-stress environments reduce anxiety in rabbits coping with changed vision. Adequate lighting helps rabbits with remaining vision make the most of their sight. If the rabbit has a bonded partner, maintaining that bond provides social support and navigation assistance. The environment should be kept at appropriate temperature, as rabbits are heat-sensitive and may be less able to find cool spots when visually impaired.

Quality of life considerations guide ongoing management decisions. Signs of good quality of life include interest in food and treats, willingness to explore within comfortable boundaries, normal grooming behaviors, relaxed posture during rest, and positive social interactions. Indicators of compromised quality of life include persistent pain behaviors, severe visual impairment affecting function, refusal to eat despite intervention, complete social withdrawal, or inability to perform basic activities. Quality of life should be assessed honestly and regularly, with treatment goals adjusted if the rabbit's wellbeing declines despite intervention.

Ongoing monitoring and veterinary follow-up ensure continued appropriate care. Regular examinations evaluate the treated eye for complications and monitor overall eye health. Intraocular pressure measurement tracks for secondary or persistent glaucoma. The fellow eye requires surveillance for development of similar problems, particularly when underlying conditions affect both eyes. General health monitoring including weight checks supports overall wellbeing. Keeping records of medications, eye appearance, and any concerns helps the veterinary team track the rabbit's course and make informed recommendations.

Caregiver support and resources help rabbit owners manage the demands of caring for a rabbit with chronic ocular disease. The House Rabbit Society provides information and connects owners with support networks. Online communities offer peer support and practical advice from others managing similar conditions. The financial and emotional demands of managing lens luxation, particularly when surgery is involved, can be significant. Having realistic expectations while maintaining hope for quality of life helps owners make sustainable decisions. Open communication with the veterinary team about concerns, limitations, and goals ensures treatment approaches remain appropriate and achievable. Recognizing when intensive care becomes unsustainable and having honest discussions about all options, including humane endpoints, benefits both owners and their rabbits.

Lens luxation in rabbits occurs primarily as a secondary condition, with breed predisposition relating more to susceptibility to underlying diseases than to direct inherited lens problems. Unlike dogs, where certain breeds carry genetic mutations causing primary lens luxation, rabbits do not have documented hereditary lens luxation. However, breeds with elevated risk for conditions that predispose to lens luxation face indirect increased risk. New Zealand White rabbits, which have genetic predisposition to primary glaucoma, may be at elevated risk for secondary lens luxation when glaucoma develops and causes globe enlargement. Any breed susceptible to E. cuniculi-related ocular disease faces risk of the lens complications that this parasite causes.

Population factors beyond specific breeds influence lens luxation risk. Rabbits from environments with high E. cuniculi prevalence, including breeding operations, rescues, and pet stores, have increased exposure to this common cause of lens problems. Older rabbits may have accumulated more years of potential exposure to damaging conditions. Rabbits with history of ocular trauma from any cause face elevated risk. Those with chronic uveitis from dental disease or other causes experience progressive zonular damage. The specific underlying conditions present in an individual rabbit determine that rabbit's risk more than breed identity alone.

Screening recommendations focus on monitoring for underlying conditions rather than breed-specific lens luxation screening. Rabbits with known risk factors, including glaucoma, E. cuniculi infection, history of uveitis, or previous ocular trauma, should receive regular comprehensive eye examinations with attention to signs of zonular instability. Phacodonesis and iridodonesis, when detected, warrant increased monitoring and management of any underlying conditions. All rabbits benefit from regular veterinary examinations including basic eye assessment. Owners should be educated about recognizing signs of eye problems and understand the importance of prompt attention when changes are noticed.

Lens luxation in rabbits most commonly occurs as a complication of or in association with other ocular diseases. Glaucoma has a bidirectional relationship with lens luxation, serving as both cause and effect. Chronic elevated intraocular pressure causes globe enlargement that stretches and eventually ruptures zonular fibers, leading to lens displacement. Conversely, anterior lens luxation causes pupillary block that obstructs aqueous drainage, causing acute severe glaucoma. This relationship means that rabbits with either condition must be monitored for development of the other. E. cuniculi infection causes many ocular problems in rabbits, including cataracts, uveitis, and damage to zonular structures that can result in lens luxation. GI stasis can develop secondary to the stress and pain of lens luxation and its complications, requiring careful attention to appetite and digestive function in any affected rabbit.

Several conditions may co-exist with or be confused with lens luxation. Cataracts frequently accompany lens luxation, either as a predisposing factor or coincidental finding, with E. cuniculi commonly causing both conditions. Uveitis often occurs with lens luxation, both as a cause and as a result of lens displacement that triggers inflammation. Aphakia, the complete absence of a lens, may be confused with posterior luxation when the lens is not visible. Retinal detachment may accompany or result from lens luxation and affects visual prognosis. Corneal edema from lens-corneal contact or secondary to pressure elevation may be the most obvious finding, with the luxated lens requiring careful examination to identify.

Complications arising from lens luxation can cause significant additional problems. Secondary glaucoma from anterior lens luxation can cause rapid, irreversible vision loss and is extremely painful. Corneal damage from direct lens contact or elevated pressure may result in permanent scarring. Uveitis triggered by lens displacement causes additional intraocular damage and discomfort. Posterior luxated lenses may migrate, potentially causing intermittent or progressive problems. Retinal detachment can occur from vitreous disturbance or traction during lens displacement. Phthisis bulbi, shrinkage and degeneration of the globe, may develop as an end stage of severe disease. These complications emphasize the importance of prompt treatment and appropriate monitoring to prevent or minimize secondary damage.
