About Brittle cornea syndrome

What is Brittle cornea syndrome?

Brittle cornea syndrome (BCS) is a rare genetic disorder that affects the cornea, the clear outer layer of the eye. It is characterized by thinning of the cornea, which can lead to vision problems, eye pain, and sensitivity to light. In some cases, the cornea can become so thin that it can rupture, leading to vision loss. BCS is caused by mutations in the ZNF469 gene, which is responsible for producing a protein that helps maintain the structure of the cornea. Treatment for BCS typically involves the use of eye drops and/or surgery to strengthen the cornea.

What are the symptoms of Brittle cornea syndrome?

The main symptom of Brittle cornea syndrome is recurrent corneal erosions, which can cause pain, redness, tearing, and blurred vision. Other symptoms may include corneal thinning, corneal scarring, and recurrent corneal ulcers. In some cases, the cornea may become so thin that it can rupture.

What are the causes of Brittle cornea syndrome?

The exact cause of Brittle cornea syndrome is unknown. However, it is believed to be an inherited disorder caused by a mutation in the ZNF469 gene. This gene is responsible for producing a protein that helps maintain the structure of the cornea. Mutations in this gene can lead to a weakened cornea, which can cause the cornea to become brittle and prone to rupture.

What are the treatments for Brittle cornea syndrome?

The main treatment for Brittle cornea syndrome is corneal transplantation. This is a surgical procedure in which the damaged cornea is replaced with a healthy donor cornea. Other treatments may include the use of contact lenses, corneal collagen cross-linking, and the use of topical medications to reduce inflammation and improve vision. In some cases, laser surgery may be used to improve vision.

What are the risk factors for Brittle cornea syndrome?

The primary risk factor for Brittle cornea syndrome is a genetic mutation in the ZNF469 gene. Other risk factors include a family history of the condition, being of Ashkenazi Jewish descent, and having a history of eye trauma or surgery.

Is there a cure/medications for Brittle cornea syndrome?

There is no cure for Brittle Cornea Syndrome, but there are medications that can help manage the symptoms. These include topical lubricants, anti-inflammatory medications, and medications to reduce the risk of infection. In some cases, surgery may be recommended to improve vision.
