Baseline examination of choroidal rupture. OCTA shows a hyporeflective line corresponding to retinal pigment epithelium (RPE)-choriocapillaris defects near to the foveal area. B-scan reveals a disruption of the RPE-Bruch membrane and a hyperreflective intraretinal area associated with backscattering effect was also present.

On OCT angiograms, the choroidal rupture appeared as a hypointense break in choriocapillaris plexus (Figure 1).
Optical coherence tomography angiography (OCTA): enface angiograms at 4-week visit. Angiograms of outer retina (A) and choriocapillaris (B) demonstrate the presence of a well circumscribed lesion with a clear hyperintense signal and characterized by numerous anastomotic vessels. Neovascular lesion extends along the primary RPE-Bruch membrane defect. OCT B-scan shows subretinal fluid.

Lesion was characterized by numerous and fine anastomotic vessels with a well-shaped peripheral arcade (Figure 2).
Optical coherence tomography angiography (OCTA): enface angiograms at 6-week visit. OCTA reveals shrinkage of the choriocapillaris defect; enface scan of outer retina and choriocapillaris show no hyperintense flow signal. OCT B-scan demonstrates partial healing of the RPE wound, covered by a less reflective RPE and a reduction of hyperreflective intraretinal material; no subretinal fluid is evident.

CNV (Figure 3). C-scans of the outer retina and choriocapillaris did not show any hyperintense signal.
