Figure 1.

Panel A shows two color fundus photographs of retinas, revealing blood vessels radiating from the optic disc. Panel B displays a black-and-white fluorescein angiography of the retina, indicating abnormal vessel patterns. Panel C presents a color retinal image alongside two cross-sectional OCT scans, depicting retinal layer irregularities. Panel D contains two grayscale ocular ultrasound images with corresponding graphs, illustrating structural abnormalities in the eye.

(A) A retinographic composition of both eyes reveals an apparently normal fundus in the RE. In contrast, the LE shows vitreous cloudiness due to vitreous hemorrhage, which obscures the details of the posterior pole. However, a flame-shaped hemorrhage is visible at the superior pole of the optic nerve near the superior temporal arcade. Periphlebitis and peripheral ischemia are more pronounced in the nasal quadrants. Notably, there is pigment redistribution in the equator and periphery, with a leopard pattern, along with a rounded yellowish choroidal mass in the inferior nasal quadrant. (B) Detail of fluorescein angiography of the left nasal fundus showing dye leakage from the optic nerve and vessels of the inferior temporal arcade toward the posterior pole. Patchy hypofluorescent images in the equator and periphery are consistent with pigment redistribution. Perivenous leakage also occurs in the vessels of the inferior nasal quadrant, as well as areas of ischemia in the inferior nasal quadrants. (C) OCT scan of the choroidal mass area shows retinal pigment epithelium undulations. (D) B-scan ocular ultrasonography Left: diffuse vitreous hyperreflectivity consistent with vitreous detachment and hemorrhage, and inferior choroidal-retinal thickening Right: detail of the inferior nasal quadrant showing partial retinal detachment.
