Unusual optic disc infarction in a case of arteritic anterior ischaemic optic neuropathy (AAION).

Herein, we report another case of arteritic anterior ischaemic optic neuropathy from Singapore, in which the initial optic disc swelling was extreme and the sequential disease resolved because the patient was already on maximum treatment. As the management of this biopsy-proven giant cell arteritis case was complicated by the presence of a number of other medical conditions, including end-stage renal failure, monitoring of the response to treatment proved problematic.
