Ruptured retinal macroaneurysm complicated by a retro hyaloidal hematoma: about a case and review of the literature.

A 45 years old patient consulted for a sudden decrease in visual acuity in the right eye. Ophthalmological examination gave visual acuity limited to luminous perceptions with a calm anterior segment, a transparent lens and at the fundus examination a dense, massive, two-level intra-retinal and retro hyaloidal pigeon nest hemorrhage with a fusiform whitish lesion on the path of the upper temporal artery. The suspected diagnosis was a complicated ruptured retinal macroaneurysm with massive retinal and retro hyaloidal hemorrhage.
