Peripheral ulcerative keratitis resulting in “contact lens cornea” due to leucocytoclastic vasculitis – A rare association
Suresh Ramchandani, Sushama RamchandaniPeripheral ulcerative keratitis (PUK) is an uncommon condition affecting 0.2–3.0 per million per year. It is an inflammatory disease of the peripheral cornea caused by complex pathological mechanisms, resulting in epithelial breakdown, stromal infiltration, and characteristic sequelae. PUK may arise from local or systemic causes, infectious or noninfectious. Local causes are usually infectious—most often viral or bacterial—though fungal and parasitic infections may also occur. Systemic causes, predominantly autoimmune, account for approximately 50% of all PUK, with rheumatoid arthritis (RA) responsible for around 34%. “Contact lens cornea” refers to the appearance of a cornea resembling a contact lens due to peripheral furrowing secondary to PUK, most often observed in RA-associated cases. We report a rare case of bilateral “contact lens cornea” secondary to leucocytoclastic vasculitis (LCV).
