Bullous keratopathy

Bullous keratopathy is a blister-like swelling of the cornea of the eye due to the endothelium of the cornea failing to function normally - resulting in swelling due to the accumulation of excessive fluid and blisters on the cornea causing blurring of vision.

(That this term concerns the cornea of the eye is indicated by the prefix "kerato-" which refers to the cornea of the eye, and is also applied to other terms in this section - listed on the left).


Bullous keratopathy is described by some sources as "water-logging" of the cornea because its effects are due to the accumulation of excessive fluid.

Bullous keratopathy is most common in older people but may occasionally occur after eye surgery, such as cataract extraction.

Bullous keratopathy is sometimes associated with the hereditary condition Fuchs' endothelial dystrophy, which can lead to Bullous keratopathy.
