Purpose: To report longitudinal changes in fellow eyes of chronic central serous chorioretinopathy (CSCR) associated choroidal neovascularization (CNV) using optical coherence tomography angiography (OCTA) and determine factors affecting neovascular conversion. Methods: Medical records of patients with chronic CSCR complicated by CNV and a minimum follow up of 6 months were reviewed. OCT and OCTA features were analyzed at baseline and final follow up. Baseline factors were assessed for predictive value against presence of CNV at follow up and conversion to exudative form. Results: Twenty-six subjects (26 CNV and 26 fellow eyes) were included in the study and followed up for a mean period of 26 ± 17 months. Nine eyes had CNV network in fellow eye at baseline, out of which three (33%) had a conversion to exudative CNV. Among the remaining 17 eyes, one eye developed a new network during a period of 44 months. An increase in the size of network was seen from 0.886 ± 0.945 mm2 at baseline to 1.326 ± 1.263 mm2 at follow up. Baseline choroidal thickness at sub-fovea was 345.4 ± 74.9 microns in eyes having network at last visit, compared to 440.1 ± 73.7 microns in eyes having no network.( p < 0.001) None of the baseline variables were found to be significantly associated with conversion to exudative form or presence of CNV on follow up in multivariate analysis. Conclusion: A conversion rate to exudative form was seen in 33% of fellow eyes with CNV. Relatively thinner choroid at baseline was associated with exudative conversion during follow up.

Abstract Background: Optical coherence tomography angiography (OCTA) is a newly developed imaging quantitative technique for analysis of choriocapillaris (CC) flow changes, thereby exploring the pathological mechanism of chronic central serous chorioretinopathy (CCSC) and the therapeutic effects of photodynamic therapy (PDT). In this study, we sought to quantify the blood flow changes in CC of CCSC patients receiving half-dose PDT using OCTA.Methods: A total of 28 affected eyes and 24 unaffected eyes of 26 CCSC patients receiving half-dose PDT, and 40 eyes of 20 healthy gender- and age-matched subjects were retrospectively enrolled in this study. The proportion of total areas of flow signal voids (FSV, %) in CC level of OCTA was assessed in both eyes of the CCSC patients at baseline and repeated in multiple sections at 1-week, 1-month, 3-month and 6-month intervals after PDT. In addition, the CC patterns in response to PDT at early stage and the subsequent morphologic changes were qualitatively documented using OCTA.Results: For affected eyes, FSV at 6-m follow-up was significantly lower than that at 1-m follow-up (p=0.036). When compared to normal control eyes, FSV in affected eyes was significantly higher at 1-m, 3-m and 6-m follow-up (p<0.05 for all), and FSV in unaffected eyes was significantly higher at baseline, 1-w, 1-m and 3-m follow-up (p<0.05 for all). Three CC patterns of early response to PDT were identified, including signs of recovery with more even flow signals, transient appearance of worse ischemia and secondary neovascularization within CC level.Conclusion: Abnormal CC flow attenuation remains in completely resolved eyes of CCSC patients treated with half-dose PDT.

AimTo evaluate the optical coherence tomography angiography (OCTA) features of fellow eyes of patients with unilateral choroidal neovascularisation (CNV) associated with chronic central serous chorioretinopathy (CSCR).MethodsMedical records of patients with chronic CSCR who had undergone OCT angiography of both the eyes were reviewed. Patients with evidence of unilateral CNV detected by conventional imaging (OCT, fluorescein angiography and/or indocyanine green angiography) were included in the study. The OCT and OCTA characteristics of fellow eyes were analysed.ResultsForty patients (80 eyes—40 fellow eyes) with chronic CSCR with evidence of CNV in one eye were included. Mean age of the patients was 54.9±9.9 years and 82.5 % were males. Twenty-five (62.5%) fellow eyes had flat irregular pigment epithelial detachment on OCT, out of which 21 had internal hyper-reflectivity. A definite vascular network was picked up by OCTA in 9 of these 40 fellow eyes (22.5%) which was not detected on conventional imaging. In addition, two eyes had an ill-defined hyper-reflectivity, which could not be classified as a definite network at that point of time. The networks detected on OCTA in fellow eyes were mostly inactive, suggesting a subclinical neovascularisation.ConclusionOne-fourth of fellow eyes showed vascular network which could not be diagnosed on conventional imaging which highlights the importance of imaging both the eyes of chronic CSCR for early detection of CNV using OCTA. Further longitudinal studies are needed to assess the clinical course of such subclinical vascular networks in CSCR.

Purpose. To assess the occurrence of choroidal neovascularization (CNV) secondary to chronic central serous chorioretinopathy (CSCR) using optical coherence tomography angiography (OCTA) and correlate these findings with choroidal thickness (CT). Materials and Methods. This retrospective study included 25 consecutive patients (43 eyes), mean age 48.12 ± 7.8 years, diagnosed with persistent CSCR. All patients underwent a complete ophthalmic examination, fluorescein angiography (FA), indocyanine green angiography (ICGA), optical coherence tomography, and OCTA. Results. CNV was confirmed in 18.6% of eyes using FA and ICGA and in 25.6% of eyes using OCTA. All cases of CNV were associated with irregular retinal pigment epithelial detachment. CT was increased in the affected eyes (mean 491.05 ± 91.98), but there were no statistically significant correlations between CT and CNV and PED occurrence (p=0.661 and p=0.614, resp.) and between CT and duration of the disease (p=0.940). Conclusions. OCTA detected CNV more frequently than other imaging modalities. CNV coexisted with irregular PED in all cases. CT was increased in eyes with chronic CSCR, but without any correlation with CNV occurrence; therefore, CT cannot be considered as a predictor of CNV occurrence. Further studies with a larger number of patients are needed to confirm these findings.

Purpose To analyze the short-term therapeutic efficacy of intravitreal injection of bevacizumab (IVB) for chronic central serous chorioretinopathy (CSC) according to the presence of choroidal neovascularization (CNV) using optical coherence tomography angiography (OCTA). Methods A retrospective chart review was perfomed on cases of CSC with CNV (Group 1: n = 31) and an age-matched cases of CSC without CNV (Group 2: n = 30). The response to IVB was evaluated by changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), choroidal thickness (CT), and pachyvessel diameter. Univariate and multivariate linear regression analyses were performed to identify factors associated with the visual outcome of chronic CSC with CNV after IVB. Results At baseline, the CT values differed significantly between Groups 1 and 2 (371.55 ± 67.09 vs. 417.33 ± 71.32 μm, p = 0.01). In Group 1, BCVA improved significantly (p < 0.001), and CMT (p < 0.001), CT (p = 0.001) and pachyvessel diameter (p = 0.045) decreased significantly, after IVB. In Group 2, only pachyvessel diameter (p = 0.001) was significantly smaller after IVB. Univariate analysis showed that the initial CT (B = 0.002, p = 0.026) and pachyvessel diameter (B = 0.002, p = 0.001) significantly affected visual outcome. In multivariate analysis, the initial pachyvessel diameter exhibited significant results (B = 0.002, p = 0.001). Conclusions IVB showed less effective short-term outcomes in chronic CSC patients without CNV than in patients with CNV. In chronic CSC with CNV, the short-term visual outcome after IVB was better in patients with a thinner choroid and smaller pachyvessels.

Proportion of total areas of flow signal voids ( FSV , %) in CC level of OCTA were mainly assessments in both eyes of the CCSC patients at baseline and repeated in multiple sections at 1-week, 1-month, 3-month and 6-month intervals after PDT. In addition , CC patterns in response to PDT at early stage and their subsequent morphologic changes were qualitatively documented using OCTA. Results: For affected eyes, significant decrease in FSV was found at 6-m follow-up than 1-m follow-up (p=0.036). Comparing to normal control eyes, FSV in affected eyes was significantly higher at 1-m, 3-m and 6-m follow-up (p<0.05 for all), while FSV in unaffected eyes was significantly higher at baseline, 1-w, 1-m and 3-m follow-up (p<0.05 for all). Three CC patterns of early response to PDT can be identified, including signs of recovery with more even flow signals, transient appearance of worsen ischemia and secondary neovascularization within CC level. Conclusion: Abnormal CC flow attenuation remained in completely resolved eyes of CCSC patients treated with half-dose PDT.
