Images were taken at the initial visit (BCVA was 0.2 in the right eye and 0.05 in the left eye) (a) Color fundus photograph of the right eye. The optic disk is pale and slightly swollen. There are telangiectatic vessels and splinter hemorrhages in the lower part of the optic disk. (b) Color fundus photograph of the left eye. The optic disk is swollen and superficial telangiectatic vessels and splinter hemorrhages are extending from the optic disk to the peripapillary retina. (c) Optical coherence tomography (OCT) imaging of the right eye. The macula is normal. (d) OCT imaging of the left eye. There is intraretinal and subretinal fluid.

In optical coherence tomography (OCT), the macula was normal in the right eye, but the intraretinal and subretinal fluid was present in the left eye (Fig. 1).
Fundus fluorescein angiography (FFA) images at the initial visit. (a) FFA image of the right eye shows hyperfluorescence at the optic disk and inferior retina. There are several microaneurysms in the posterior pole. (b) There are telangiectatic vessels in the upper retina of the right eye. (c) FFA image of the left eye shows hyperfluorescence at the optic disk. There are telangiectatic vessels in the nasal retina. (d) FFA image of the left eye shows hyperfluorescence at the optic disk. There are several microaneurysms in the posterior pole.

At the same time, there were ischemic areas in the peripheral retina in both eyes (Fig. 2).
Humphrey's central 30-2 visual field images of both eyes at the initial visit. (a, b) There are peripheral visual field defects in both eyes.

Humphrey's central 30-2 visual field test was abnormal in both eyes (Fig. 3).
Fundus fluorescein angiography (FFA) images at 6th month. (a) There are several microaneurysms in the posterior pole of the right eye. (b) Telangiectatic vessels in the upper retina have disappeared. Ischemia and several microaneurysms are seen in the upper retina. (c) Telangiectatic vessels in the nasal retina have disappeared. (d) There are several microaneurysms in the posterior pole of the left eye.

Both optic disks were pale at the end of 6 months of follow-up (Fig. 4).
Images were taken in the 6th month (BCVA was 20/40 in the right eye and 20/63 in the left eye) (a, b) color fundus photograph of the right and left eye. All telangiectatic vessels and splinter hemorrhages have disappeared. (c, d) OCT imaging of the right and left eye is normal.

In FFA in both eyes, there was an enlarged foveal avascular zone, a small amount of microaneurysm in the posterior pole, and focal ischemic areas with a small number of telangiectatic vessels in the peripheral retina (Fig. 5).
