Non-homogenous hyperreflectivity in choriocapillaris layer on OCTA implies early treatment with anti-VEGF for central serous chorioretinopathy

Introduction: Optical coherence tomography angiography (OCTA) facilitates the detection of the choroidal neovascularization (CNV). This study explored the role of non-homogenous hyperreflectivity implying putative CNV in choriocapillaris layer on OCTA in central serous chorioretinopathy (CSCR). Methods: Thirteen eyes out of 12 patients with CSCR were examined with OCTA. The non-homogenous hyperreflectivity was compared with the histological morphology of experimental CNV. The effect of intravitreal anti-vascular endothelial growth factor (VEGF) was evaluated by analyzing the changes of central macular thickness (CMT) and the height of subretinal fluid (SRF). Results: Comparison of the non-homogenous hyperreflectivity on OCTA with the established CNV in two animal models strongly indicated these signals are putative CNV. During following-up, these non-homogenous hyperreflectivity in CSCR developed into visible CNV on OCTA. Moreover, anti-VEGF treatment was effective to reduce both the SRF and CMT in CSCR with non-homogeneous hyperreflectivity or secondary CNV within 2 months. Conclusion: This study suggested that the non-homogenous hyperreflectivity on OCTA could be served as a diagnostic biomarker for putative CNV in CSCR, implying early treatment with anti-VEGF.
