Issue Name

Meibomian Cyst

Other Names
Chalazion, Tarsal Cyst, Meibomian Gland Lipogranuloma

Issue Description

A chalazion is a cyst in the eyelid that is caused by inflammation of a blocked meibomian gland, usually on the upper eyelid. Chalazions differ from styes (hordeolums) in that they are usually painless apart from the tenderness caused when they swell up, and in size (chalazia tend to be larger than styes). A chalazion may eventually disappear on its own after a few months, though more often than not, some treatment is necessary.

Symptoms


  • Swelling on the eyelid
  • Eyelid tenderness
  • Sensitivity to light
  • Increased tearing
  • Heaviness of the eyelid
  • Sleepyness

  • Diagnosis

    You or your doctor can diagnose a chalazion by looking at it. Chalazions usually go away on their own without medical attention.

    Causes

    The condition is caused by obstruction of one of the ducts that drains one of the Meibomian glands.

    Treatment

    The primary treatment is application of warm compresses for 10 - 20 minutes at least 4 times a day. This may soften the hardened oils blocking the duct and promote drainage and healing. Topical antibiotic eye drops or ointment (eg chloramphenicol or fusidic acid) are sometimes used for the initial acute infection, but are otherwise of little value in treating a chalazion. Chalazia will often disappear without further treatment within a month or so. If they continue to enlarge or fail to settle within a few months, they may be surgically removed using local anesthesia. This is usually done from underneath the eyelid to avoid a scar on the skin. Rarely chalazia may reoccur and these will be biopsied to help rule out tumors.

    ASPCA

    The American Society for the Prevention of Cruelty to Animals® (ASPCA®) was the first humane society to be established in North America and is, today, one of the largest in the world.

    Our organization was founded on the belief that animals are entitled to kind and respectful treatment at the hands of humans and must be protected under the law. Headquartered in New York City, the ASPCA maintains a strong local presence, and with programs that extend our anti-cruelty mission across the country, we are recognized as a national animal welfare organization. We are a privately funded 501(c)(3) not-for-profit corporation, and are proud to boast more than 2 million supporters across the country.

    The ASPCA’s mission, as stated by founder Henry Bergh in 1866, is “to provide effective means for the prevention of cruelty to animals throughout the United States.”

    Rescue Me

    Jeff Gold, Founder, Rescue Me! Animal Rescue Network

    Jeff Gold lives in Watkinsville, Georgia on the same property as Rescue Me's Animal Rehabilitation Center, with 18 rescue animals. Shown with him in the photo to the left are Maggie, Izzie and Cortez. In 2003, after learning there was nobody doing boxer rescue work in Georgia, Gold founded Boxertown, an organization which helped find homes for over 500 boxers during its first two years. Based upon this success, Gold came up with the vision for Rescue Me! ― a network which helps all breeds of dogs, cats and other animals find good homes, anywhere in the world. RescueShelter.com is also a free service of Rescue Me! and provides the world's largest and most up-to-date directory of animal rescue organizations for all breeds of dogs, cats and other animals, including a comprehensive directory of wildlife rehabilitators in over 150 countries.
