Peripheral retinal edema: a–c Right eye of a 61-year-old patient with VA of 20/20 with vitreous hemorrhage. Thickness map shows a peripheral retinal edema as the peak is located outside the ETDRS area but that widely overflowed into the ETDRS grid. B-scan displays retinal thickening starting from the peak located peripherally that decrease steadily to reach the foveola. The peripheral peak contains microaneurysms that are probably the origins of the leakage. d–f Right eye of a 61-year-old patient with VA of 20/20. Thickness map shows no main DME, but an isolated peripheral retinal edema is detected outside the ETDRS area that minimally overflow into the grid. B-scan displays a preserved foveola, and the retinal edema contains a small cyst with hard exudates and microaneurysm
