    Optical coherence tomography angiography findings in pigmented paravenous chorioretinal atrophy

    Purpose: To analyze the retino-choroidal vascular characteristics of patients affected by pigmented paravenous chorio-retinal atrophy (PPCRA) by means of optical coherence tomography angiography (OCTA). Methods: The study was designed as an observational, cross-sectional case series. Multimodal imaging included fundus autofluorescence (FAF), structural optical coherence tomography (OCT) and OCT angiography (OCTA). The quantitative OCTA analyses included the calculation of the vessel density (VD) and choriocapillaris porosity. Results: Overall, 12 patients (24 eyes) affected by PPCRA were recruited. Structural OCT of the areas involved by PPCRA as visualized on FAF showed a complete EZ and ELM absence, with thinning of ganglion cell ...
