case_images: Fundus examination revealed edema and hyperemia in the head of the optic disk, 360-degree retinal hemorrhages in the peripheral retina, sheathing and occlusion of the vessels, and 2+ vitreous cells (Figures 1 and 2).

case_images: Fundus examination revealed edema and hyperemia in the head of the optic disk, 360-degree retinal hemorrhages in the peripheral retina, sheathing and occlusion of the vessels, and 2+ vitreous cells (Figures 1 and 2).
case_images: Fundus fluorescein angiography montage image (Canon 60UVi, Tokyo, Japan) showing ischemic areas in the laser periphery, leakage in the head of the optic disk, and vasculitis.

case_images: Fluorescein angiography (Canon 60UVi, Tokyo, Japan) performed five days after laser photocoagulation revealed that laser application to the rear of the peripheral ischemic area had been effective, and leakage was detected in the optic disk (Figure 3).
case_images: Wide-angle fundus photograph and fundus autofluorescence (FAF) images (Optos PLC, Dunfermline, UK). The laser photocoagulation therapy was effective, and no pathology was observed in the retina.

case_images: The patient's visual acuity reached 0.3 at the end of 11 months, and no pathology was observed in the retina (Figure 4).
case_images: Right eye findings after 4.5 years: (a) wide-angle fundus photograph (Optos PLC, Dunfermline, UK), (b) fundus fluorescein angiography late phase image (Optos PLC, Dunfermline, UK), and (c) macular OCT image (Optovue RTVue, RT 100, software version 6.3, Optovue, CA, USA), atrophy in the outer retinal layers, irregularity in the ellipsoid zone, cystoid macular edema, and epiretinal membrane.

case_images: fig5
case_images: The patient was followed up for a total of 4.5 years, and no recurrence or other ocular involvement was observed after 1.5 years (Figures 5(a) and 5(b)). Although an epiretinal membrane, minimal cystoid changes, atrophy in the outer retinal layers, and impaired integrity of the ellipsoid zone were determined on macular OCT at the final examination (Figure 5(c)), the best-corrected visual acuity on a Snellen chart remained stable at 0.3.
