Argon laser photocoagulation for the treatment of idiopathic, bilateral, recurrent, diffuse retinal arterial...

Spontaneous resolution of retinal arterial aneurysms may occur, but recurrences are uncommon. A case of idiopathic, bilateral, recurrent, diffuse retinal arterial aneurysms treated with direct laser photocoagulation is described. A 30-year-old woman with a history of physiologic menopause was found to have bilateral, diffuse, multiple retinal arterial aneurysms with massive subretinal exudates and intraretinal hemorrhages. Fluorescein angiography demonstrated multiple retinal arterial aneurysms with leakage. Direct argon laser photocoagulation successfully closed the aneurysms. During 6 years of follow-up, the aneurysms reoccurred twice, coinciding with a postpartum period. Recurrences were successfully treated with repeated laser photocoagulation with the aneurysms closed off. Hormonal imbalance may play a role in this condition. Recurrent retinal arterial aneurysms can be managed by direct laser photocoagulation.
