Abstract
Purpose
To investigate the dynamic changes and possible affecting variables of outer retinal microstructure in macular area of central serous chorioretinopathy (CSC) patients.
Methods
This was a retrospective study. The data of optical coherence tomography (OCT) and autofluoroscopy (AF) of 36 CSC patients admitted to our hospital from February 2012 to February 2013 were included. Dynamic variations and possible correlated variables of central retinal thickness (CRT), subretinal fluid diameter (SRFD), ellipsoid zone (EZ), interdigitation zone (IZ) and/or hyperautofluorescent spot (HAS) were analyzed.
Results
The outer retinal microstructure was gradually restored along with the subretinal fluid absorption during the follow-up. EZ in 94.4% (34/36) and the IZ in 100% (36/36) eyes were completely disappeared at baseline and restored (completed or incomplete) in 88.9% (8/9) and 44.4% (4/9) eyes, respectively, after 6-month follow-up. HAS was evident in 25% eyes (8/32 eyes) at baseline, and the density was initially increased and then declined during follow-up. Correlation analysis demonstrated that the restoration of EZ and IZ was correlated with the restoration period and subretinal fluid absorption.
Conclusion
The outer retinal microstructure was restored during the subretinal fluid absorption in CSC patients, with EZ restored earlier than IZ. The restoration period and the absorption of subretinal fluid were two closely correlated variables of macular microstructure restoration.
