Abstract
PURPOSE: To assess the rate of choroidal neovascularization (CNV) detected by optical coherence tomography angiography (OCTA) in flat irregular pigment epithelium detachment (PED) in chronic central serous chorioretinopathy. METHODS: Data on all consecutive patients with chronic central serous chorioretinopathy who underwent OCTA over a 1-year period were reviewed. The presence of flat irregular PED, which was defined as an irregular elevation of the retinal pigment epithelium allowing the visualization of a distinct Bruch's membrane was assessed on high-resolution OCT B-scan. Clinical, multimodal imaging, and OCTA data were reviewed by two graders for the detection of CNV. RESULTS: Eighty-eight eyes of 61 patients with chronic central serous chorioretinopathy were included. Patient mean age (±SD) was 54.5 ± 12.2 years, and 78.7% were males. Mean subfoveal choroidal thickness (±SD) was 452.6 ± 145.6 μm. Flat irregular PEDs were detected in 59 eyes of 51 patients. OCTA detected the presence of CNV in flat irregular PEDs in 35.6% of cases. Conversely, using the combination of spectral domain optical coherence tomography angiography, fluorescein and indocyanine green angiography, CNV was detected in only 25% of flat irregular PEDs. All hyporeflective flat irregular PEDs on OCT were avascular on OCTA while they were at least partially hyperreflective when associated with CNV. CONCLUSION: One-third of flat irregular PEDs in chronic central serous chorioretinopathy contained CNV. OCTA detected CNV more frequently than the other imaging modalities. Further longitudinal studies are needed to assess the indication of antivascular endothelial growth factor treatments in such cases.
