A woman in her early 30s presented with floaters that had been present for several years. Her best-corrected visual acuity was 1.5 (20/13) OU. Axial length was 27.93 mm OD and 27.35 mm OS. Numerous aneurysms were observed temporal to the macula, predominantly in the left eye (Figure, A). Swept-source optical coherence tomography angiography confirmed that these aneurysms were located in the retinoschisis cavity (Figure, B). Fluorescein angiography showed tortuosity of capillaries and aneurysms around the macular with minimal leakage from the aneurysms. She did not have any history of systemic diseases, including diabetes. Aneurysmlike structures and disrupted retinal capillaries in the setting of myopic retinoschisis have been described.1 Reported features include saccular aneurysmlike structures and disrupted retinal capillaries, but the layer in which the aneurysms exist is not clear. These findings are consistent with the previous description and support the hypothesis of physical capillary disruption during inner retinal schisis enlargement.
