Bullous keratopathy
Bullous Keratopathy (pronunciation: buh-luhs ker-uh-top-uh-thee) is a pathological condition of the cornea characterized by the development of fluid-filled blisters, or bullae, on the corneal surface.
Etymology
The term "Bullous Keratopathy" is derived from the Latin word "bullous" meaning "bubble" and the Greek word "keratopathy" meaning "disease of the cornea".
Definition
Bullous Keratopathy is a condition where the inner layer of the cornea, the endothelium, fails to function properly, leading to fluid accumulation and the formation of painful blisters on the cornea's surface. This condition can cause significant visual impairment and discomfort.
Causes
The most common cause of Bullous Keratopathy is damage to the corneal endothelium during eye surgery, particularly cataract surgery. Other causes can include Fuchs' dystrophy, a genetic disorder affecting the corneal endothelium, and corneal edema.
Symptoms
Symptoms of Bullous Keratopathy include blurred vision, pain, and sensitivity to light. The condition can also cause a feeling of something being in the eye, known as a foreign body sensation.
Treatment
Treatment options for Bullous Keratopathy include the use of hypertonic saline eye drops to draw fluid out of the cornea, and surgical procedures such as penetrating keratoplasty (corneal transplant) or Descemet's stripping endothelial keratoplasty (DSEK).
