(a) The fundus photograph of the right eye shows disc swelling, multiple dot-like retinal hemorrhages, venous tortuosity, and a gray-white opacity in the papillomacular bundle. (b) Spectral-domain optical coherence tomography illustrates a hyperreflective band in the level of INL, and in infrared reflectance image, a grayish lesion with sharp borders in the papillomacular bundle can be observed. (c) Fundus autofluorescence shows the lesion as a hypoautofluorescence lesion. (d) The late phase of fluorescein angiography (3' : 1'') discloses no significant nonperfusion area. (e) 3*3 mm en face optical coherence tomography angiography image of the right eye lesion revealed edema in the level of deep capillary plexus.

The left eye was entirely normal (Figure 1(a)). INL was noticed (Figure 1(b)). In fundus autofluorescence, the white opacity in the fundus examination was revealed as a hypoautofluorescence lesion (Figure 1(c)). Fluorescein angiography disclosed a slight delay in the venous phase without any significant nonperfusion area in the late phase (Figure 1(d)). Optical coherence tomography angiography images of the retinal lesion area showed flow deficit in the level of the choriocapillaris and a hyperreflective area in the level of the deep capillary plexus (Figure 1(e)).
Fundus imaging following one month. (a) Fundus photograph of the right eye shows the vanishing of dot-like retinal hemorrhages and decrease in the opacity of papillomacular bundle lesion. (b) SD-OCT of the right eye revealed diminution in the thickness and edema of the hyperreflective retinal lesion.

Macular SD-OCT demonstrates decreased thickness and attenuation of the hyperreflective band in INL (Figure 2).
