CHANGE OF CHOROIDAL VOLUME IN UNTREATED CENTRAL SEROUS CHORIORETINOPATHY. Issue 9 (September 2017) - Pertl, Laura
Abstract : Purpose: Choroidal hyperpermeability plays a central role in the pathophysiology of central serous chorioretinopathy (CSC). In active CSC undergoing treatment, choroidal thickness decreases if subretinal fluid (SRF) resolves. This study aimed to investigate the change in choroidal thickness and volume in eyes with untreated CSC. Methods: The authors retrospectively analyzed 27 eyes with treatment-naïve CSC (25 patients), who had a follow-up of 4 to 6 weeks. Retinal and choroidal volume and SRF were segmented manually and calculated using the Spectralis OCT built-in software (Spectralis; Heidelberg Engineering). Results: In treatment-naïve eyes with CSC, an increase in SRF was significantly associated with an increase in choroidal thickness and volume (rho = 0.93, P < 0.01). Eyes with greater baseline choroidal volume showed a significantly greater decrease in SRF during follow-up (rho = −0.47, P = 0.03). Conclusion: In this study, an increase in SRF was associated with an increase in both choroidal thickness and volume in eyes with treatment-naïve CSC. Eyes with thicker baseline choroidal volume showed a greater reduction in SRF. Abstract : Supplemental Digital Content is Available in the Text.This study is the first to show that an increase in subretinal fluid is associated with an increase in choroidal volume in treatment-naïve eyes with central serous chorioretinopathy.
