Bullous Keratopathy
Key Points
Bullous keratopathy is caused by edema of the cornea, most frequently due to Fuchs corneal endothelial dystrophy or corneal endothelial trauma. Subepithelial fluid-filled bullae form, leading to decreased visual acuity, loss of contrast, glare, and photophobia. Slit-lamp examination reveals corneal epithelial bullae and swelling of the corneal stroma. Treatment by an ophthalmologist is required.
