Retinal structural changes associated with retinal arterial macroaneurysm examined with optical coherence tomography.

Full Abstract

PURPOSE: To study the retinal structural changes associated with a retinal arterial macroaneurysm and their association with visual prognosis. METHODS: We studied retrospectively the medical records of 44 eyes of 44 patients with a retinal arterial macroaneurysm; all eyes showed hemorrhagic and/or exudative changes of the fovea with a visual disturbance. The retinal structural changes were examined by optical coherence tomography (OCT). RESULTS: At the initial visit, 30 eyes (68%) showed severe hemorrhagic complications. In eyes with subretinal hemorrhage beneath the fovea, retinal structure was relatively preserved at the initial visit. At the final visit, however, foveal structure was often degenerated, especially in its outer aspect, with limited visual recovery. The 14 eyes (32%) with minimal hemorrhagic complications showed an extensive exudative change caused by the aneurysm. In 13 of these eyes, OCT examination revealed extensive retinal edema, predominantly in the outer retina. Retinal edema beneath the fovea caused a focal serous retinal detachment in 12 eyes. Eight eyes with extensive exudative change showed an accumulation of hard exudates in the macular area, and visual recovery of these eyes was often limited. CONCLUSION: Subretinal hemorrhage or extensive exudative change from a retinal arterial macroaneurysm can cause destruction of the foveal outer photoreceptor layer, resulting in a poor visual outcome.
