A cat presented for deterioration of a superficial corneal ulcer already under treatment. Bacterial keratomalacia with presumed concurrent uveitis was diagnosed. The cat was treated with topical antibiotic, autologous serum and atropine drops, and oral antibiotic and non-steroidal anti-inflammatories. There was sufficient improvement within the first 24 hours to elect to continue with medical treatment alone. The cat remained hospitalised for 4 days for intensive treatment until the malacia had resolved and the ulceration could be treated at home. Ulceration resolved within 4 weeks This case highlights how corneal ulcers can deteriorate very quickly. It emphasises how thorough investigation can aid in choosing treatment. Some malacic corneal ulcers respond to medical management alone and surgery is not always necessary. Case presentation, patient temperament, initial response to treatment, and owner compliance and financial considerations all play a role in treatment choice for keratomalacia.
