Fundus examination revealed areas of retinal opacification around the macula [Figure 1a and b]. Optical coherence tomography showed increased reflectivity and thickness of the inner retina layers [Figure 1c].
(a-c) Fundus fluorescein angiography at 1st presentation showed an arm-to-retina time of 28 s and an arteriovenous transit time of 8 s with late hyperfluorescence in the perifoveal capillary area

Fundus fluorescein angiography showed an arm-to-retina time of 28 s and an arteriovenous transit time of 8 s with late hyperfluorescence in the perifoveal capillary area [Figure 2].

Fundus examination showed hyperemic disc, retinal opacification, cherry red spot, box-carrying of vessels with triangular hypopigmented whitish subretinal lesions with apex toward the macula [Figure 3].

Retinal examination showed pale disc, arterial narrowing, and retinal pigment epithelial changes in the posterior pole and in the triangular wedge-shaped area [Figure 4a]. The fundus picture showed optic disc atrophy, narrowed arteries, and a more prominent segmental chorioretinal atrophic patch temporal to fovea with the apex toward the macula (triangular sign of Amalric) [Figure 4b].
