a1, b1, c1, d1, e1 Color fundus photograph (a1) of the right eye showed a superior temporal arteriolar narrowing within macular area. Fluorescein angiography (FA) (b1) depicted a branch retinal arterial occlusion (BRAO) in the superior temporal macula of the right eye. Optical coherence tomography angiography (OCTA) perfusion map 6 × 6 mm of superficial and deep capillary plexuses (c1, d1) of the right eye revealed temporal parafoveal hypoperfusion. B-scan OCT (e1) of the right eye showed thinning of the inner retina temporal to the fovea, f1, g1, h1, i1, j1 color fundus photograph (f1) of the left eye showed no abnormalities within the macula area. FA (g1) demonstrated non-perfusion associated with leakage in the temporal periphery of the left eye. OCTA perfusion map 6 × 6 mm of superficial and deep capillary plexuses (h1, i1) of the left eye revealed small spots of decreased vascular perfusion within the macular area. Thinning of the inner retina temporal to the fovea was also observed on B-scan OCT in the left eye (j1), a2, b2, c2, d2, e2 at 6-month follow-up, although color fundus photograph (a2) of the right eye did not reveal any change in comparison with the baseline exam, the signs of BRAO disappeared on FA (b2). OCTA perfusion map 6 × 6 mm of superficial and deep capillary plexuses (c2, d2) of the right eye showed an impressive improvement of vascular perfusion in the previous baseline hypoperfused areas, e2 thinning of the inner retina temporal to the fovea of the right eye remained at 6-month follow-up, f2, g2, h2, i2, j2 at 6-month follow-up, the color fundus photograph (f2) of the left eye did not reveal any change in comparison with the baseline exam, and the FA (g2) revealed new vascular staining on the temporal superior vascular arcade (arrow) and maintenance of peripheral vascular leakage. OCTA perfusion map 6 × 6 mm of superficial and deep capillary plexuses (h2, i2) of the left eye showed improvement of previous small hypoperfused areas, j2 thinning of the inner retina temporal to the fovea of the left eye remained at 6-month follow-up
