Serous macular detachment associated with retinal arterial macroaneurysm.
OBJECTIVE
To report optical coherence tomography (OCT) findings of macular edema secondary to retinal arterial macroaneurysms.


METHODS
Six eyes with retinal arterial macroaneurysms were retrospectively examined by OCT. All eyes had macular edema without massive macular hemorrhage. Fluorescein angiography was performed in six eyes, and indocyanine green angiography was done in four eyes. Five eyes underwent direct laser photocoagulation to the retinal arterial macroaneurysms. The foveal thickness, height of the serous macular detachment, and visual acuity (VA) were evaluated from the initial examination until the macular edema resolved.


RESULTS
In all six eyes, the macular edema secondary to retinal arterial macroaneurysms comprised a serous macular detachment with retinal swelling. No cystoid macular edema was observed in any eyes. Dye leakage occurred only from the macroaneurysms in all eyes. OCT showed complete resolution of the serous macular detachment and retinal swelling 1 to 4 months after the initial examination. Macular hard exudates developed during absorption of the serous macular detachment in all eyes. VA improved more than two lines in all eyes after the macular edema resolved.


CONCLUSIONS
Retinal arterial macroaneurysms may leak extravasated fluid into the subretinal space, which may result in a serous macular detachment.
