Background:
To evaluate choriocapillary vascular density (CVD) in eyes with central serous chorioretinopathy (CSC) complicated by choroidal neovascularization (CNV), at baseline and after intravitreal injections (IVR) of Ranibizumab, using optical coherence tomography angiography (OCTA).
Methods:
Twelve eyes of 12 patients were enrolled as group 1 and 12 unaffected fellow eyes formed group 2. Twelve eyes of 12 healthy controls were the control group.
Results:
CVD in Group 1 did not differ before and after treatment. CVD of Group 1 was significantly lower compared with controls at baseline (whole, parafovea and fovea p < 0.05). CVD of controls resulted significantly higher than Group 2 at baseline (whole, parafovea and fovea p < 0.05). There were not significant differences in CVD between Groups 1 and 2 at baseline (p > 0.05).
Conclusions:
OCTA revealed a choriocapillary hypoperfusion that may be responsable for the beginning of this disease and the late development of CNV.
