Figure 3 Pre-treatment 9-direction panoramic fundus photograph and fluorescein angiography of the right eye. (A) Nine-direction panoramic fundus photograph on day 4 showing optic disc edema with vascular proliferation resembling angiomatosis. This was associated with peripapillary vascular dilation and surrounding exudates. The exudates extend into all peripheral quadrants. Posterior vitreous detachment extending to the midperiphery, preretinal hemorrhage, and mild vitreous hemorrhage were also noted. No findings suggestive of Coats disease or acute retinal necrosis are present. (B) Fluorescein angiography on day 7 showing optic disc vascular dilation and leakage, with leakage from the peripheral retinal vessels in all quadrants. No vascular anastomoses are observed. Fluorescence at the posterior pole is blocked by a vitreous hemorrhage beneath the posterior vitreous detachment. Arrowheads indicate angiomatosis-like vascular proliferation.
