Corneal dystrophy

Corneal Dystrophy

Corneal dystrophy (/kɔːrˈniːəl dɪsˈtrəfi/) is a group of rare genetic disorders characterized by bilateral abnormal deposition of substances in the transparent front part of the eye, the cornea.

Etymology

The term "corneal dystrophy" derives from the Greek words "korone" (pupil) and "dystrophy" (degeneration), indicating the degenerative nature of these conditions affecting the cornea.

Types

There are over 20 types of corneal dystrophy, including:

• Fuchs' dystrophy
• Lattice corneal dystrophy
• Map-dot-fingerprint dystrophy
• Granular corneal dystrophy
• Meesmann corneal dystrophy

Each type of corneal dystrophy can affect different parts of the cornea and can cause different symptoms and complications.

Symptoms

Symptoms of corneal dystrophy can vary greatly depending on the type and severity of the condition. They may include:

• Blurred vision
• Eye pain
• Light sensitivity
• Eye redness
• Vision loss

Causes

Corneal dystrophies are usually caused by abnormal gene mutations. They are typically inherited in an autosomal dominant manner, which means one copy of the altered gene in each cell is sufficient to cause the disorder.

Treatment

Treatment for corneal dystrophy depends on the type and severity of the condition. It may include:

• Eye drops or ointments
• Contact lenses
• Corneal transplantation

• Genetic disorder
• Vision impairment
