Multimodal imaging evaluation of the patient with Perifoveal Exudative Vascular Anomalous Complex (PEVAC) in the right eye. (a) Multicolor  imaging showing an isolated large aneurysmal retinal dilation featuring the PEVAC (white arrow), with concomitant myopic chorioretinal degeneration. (b and c) Late frame of fluorescein angiography (FA) (b) and indocyanine green angiography (ICGA) (c) showing a well-defined hyperfluorescent retinal lesion with slight leakage on FA examination and no leakage at ICGA. (d) Two different slabs of combined infrared reflectance and horizontal structural optical coherence tomography passing through the lesion showing a round aneurysmal lesion (white arrows) with a hyperreflective wall and intraretinal cystic spaces. (e) optical coherence tomography (OCT)-angiography images and corresponding B-scans with flow well show the PEVAC lesion as an isolated large aneurysmal retinal dilation with detectable flow in the superficial capillary plexus (first panel), deep capillary plexus (second panel) and avascular slab (third panel) (white arrows). Of note, no other telangiectatic lesions are shown around PEVAC.

Fundus examination in the right eye showed myopic chorioretinal degeneration with a concomitant PEVAC (Figure 1(a)). Fluorescein angiography (FA) and indocyanine green angiography showed a well-defined hyperfluorescent retinal lesion, with slight leakage in the late frame of FA examination (Figure 1(b) and (c)). Structural optical coherence tomography (OCT) showed a round lesion with a hyperreflective wall associated with intraretinal cystic spaces (Figure 1(d)). OCT-angiography nicely disclosed an isolated large aneurysmal retinal dilation featuring the PEVAC with detectable flow in superficial capillary plexus, deep capillary plexus (DCP) and avascular slab (Figure 1(e)).
Multimodal imaging evaluation of the myopic patient in the left eye. (a) Multicolor  imaging showing an oblique insertion of the optic disc (i.e. tilted disc) with an atrophic peripapillary halo and concomitant myopic chorioretinal degeneration. (b and c) Late frame of fluorescein angiography (b) and indocyanine green angiography (c) showing an irregular and spread hyper and hyporeflective alteration involving the foveal area. (d) Combined infrared reflectance and structural optical coherence tomography passing through the fovea showing a well-defined subretinal hyperreflective lesion (white arrows) without evidence of exudation.

Fundus examination in the left eye showed myopic chorioretinal degeneration complicated by a subfoveal fibrovascular lesion (Figure 2).
