Peripheral ulcerative keratitis as a complication of acute myeloid leukaemia.

We report a rare presentation of acute bilateral peripheral ulcerative keratitis (PUK) in a patient with a new diagnosis of untreated acute myeloid leukaemia (AML). To the best of our knowledge, this is the first report of PUK associated with untreated AML and we stress the importance of a rapid and thorough testing to exclude other diagnoses. The patient lost his vision within 10 days to counting fingers. Rapid diagnosis allowed a good visual recovery following prompt treatment with oral steroids and systemic chemotherapy treatment for the AML.
