To evaluate the optical coherence tomography angiography (OCT-A) features of a peripapillary intrachoroidal cavitation (ICC) in a patient with high myopia.
A 67-year-old woman with ICC underwent visual acuity testing, refraction, slit-lamp biomicroscopy, dilated fundus examination, and OCT-A. The main findings are described in this case report.
Best-corrected visual acuity was 20/20 in both eyes. Fundus examination revealed in the right eye a macular scar, a tilted disc along with a peripapillary staphyloma, and an orange-yellowish lesion on the inferior border of the disc. Structural OCT B-scan showed ICC as an intrachoroidal hyporeflective space located below the normal plane of the retinal pigment epithelium adjacent to the optic nerve head. Optical coherence tomography angiography showed the cavitation as a hyporeflective area, devoid of detectable flow from the choriocapillaris and large choroidal vessels layers, suggesting the choroid, including the residual hyperreflective tissue in the outer aspect of the retinal pigment epithelium/Bruch membrane, to be avascular in ICC.
Optical coherence tomography angiography demonstrated the absence of choroidal and choriocapillary network.
