Introduction:
Retinal arterial macroaneurysms are ectatic modifications of the arterial wall. They are a relatively uncommon condition wich can threaten visual function by pre- or subretinal hemorrhage in case of rupture or by massive macular exudation.
Observation:
We report a case of a 50 years old patient, without cardio-vascular history, who presented an arterial macroaneurysm complicated by premacular hemorrhage. Spontaneous evolution was aneurysm occlusion with complete hemorrhage regression and visual recovery.
Comments And Conclusion:
Retinal macro-aneurysms are acquired malformations, often isolated and located in a temporal artery. Their evolution is unpredictable either towards spontaneous occlusion, occurrence of chronic exsudative retinopathy or hemorrhagic complications by fissuration or rupture of arterial wall. Through this observation, the authors discuss the evolution and therapeutic modalities of this affection.
