Fundus photograph after 1 week showing whitish-yellow appearance of the posterior pole with macular edema [Figure 1].
(a) Fluorescein angiography frames of left eye (10 s after injection), during the early arteriovenous (A-V) phase shows normal filling of the retinal arterioles. (b) Complete filling of arterioles with lamellar flow of dye in the veins. There is hypo-fluorescence in the macular region, corresponding to the area with most marked retinal swelling. (c) Temporal arcades still showing lamellar flow in veins. (d) Complete filling of arterioles and veins. A-V transit time was increased (25 s). There was persistent absence of fluorescence at macula due to obliteration of vessels

FA frames of left eye (After 10 s of injection of dye), during the early arteriovenous (A-V) phase shows normal filling of the retinal arterioles with patchy choroidal fluorescence [Figure 2a]. Figure 2b showing complete filling of arterioles with lamellar flow of dye in the veins. Temporal arcades still showing lamellar flow of fluorescence in the veins and hypo-fluorescence at the macula [Figure 2c]. Figure 2d shows complete filling of arterioles and veins.
(a-d) Fluorescein angiography late frames of the periphery of temporal, nasal, and superior quadrants respectively showing complete vascular filling defects. There are focal areas of blocked fluorescence in the temporal quadrant corresponding to the area of retinal hemorrhages

There are focal areas of blocked fluorescence in the temporal quadrant corresponding to the area of retinal hemorrhages [Figure 3a-d].
(a) Fluorescein angiography (FA) of right eye showing normal study. (b) FA frame 5 min after injection of the dye still shows complete absence of filling in the macular region and faint perivascular and optic disc leak

FA of right eye showing normal study [Figure 4a]. FA frame 5 min after injection of the dye still shows complete absence of filling in the macular region and faint perivascular and optic disc leak [Figure 4b].
