[Natural history of an optic disc macroaneurysm]

Abstract

Case report: A 75-year old man with reduced vision in his left eye (0.05) presented with hypertensive retinopathy, retinal haemorrhages and cotton wool spots in the papillomacular bundle, as well as macular oedema. Fluorescein angiography showed a saccular hyperfluorescent lesion corresponding to arterial macroaneurysm on the optic disc, with the optical coherence tomography demonstrating macular oedema. At 2 months follow-up, vision had improved to 0.7 with spontaneous closure of the macroaneurysm and resolution of the macular oedema.

Discussion: Arterial macroaneurysms on the optic disc are unusual and are difficult to diagnose clinically. There is no safe and effective treatment, and our case, as the few single cases reported, showed that they can spontaneously close and enable visual function to recover.
