Which depth category is Descemetocele?

• A. Superficial
• B. Deep
• C. Descemetocele
• D. Iris prolapse

Answer: (C)

Descemetoceles are the deepest non-perforating corneal ulcers, where stroma is eroded away and Descemet's membrane (with endothelium) remains. This level of involvement defines the depth category you’re describing, hence the term itself. It signals imminent perforation and requires urgent attention. Superficial or mid-stromal ulcers are shallower, involving only the front parts of the cornea, while iris prolapse is a different complication that occurs when a full-thickness wound allows the iris to protrude through the defect.
