Abstract
BACKGROUND: The present study compared clinical features and outcomes of central serous chorioretinopathy (CSC) with and without pachychoroid. METHODS: It was a retrospective, longitudinal, record-based study which included eyes with CSC. Patients underwent spectral domain optical coherence tomography and differentiated between pachychoroid and non-pachychoroid groups. Eyes were divided into pachychoroid and non-pachychoroid groups based on the subfoveal choroidal thickness of 300 microns and the presence of pachyvessels. RESULTS: A total of 250 eyes of 250 patients were divided into pachychoroid and non-pachychoroid with 125 eyes in each group. Mean ages of patients in pachychoroid and non-pachychoroid groups were 45.7 ± 9.4 years and 47.4 ± 10.2 years, respectively. Mean initial best-corrected visual acuity (BCVA) was 0.40 ± 0.42 in pachychoroid and 0.39 ± 0.38 in non-pachychoroid group (p = 0.9). Mean final BCVA was 0.37 ± 0.9 in pachychoroid and 0.21 ± 0.33 in non-pachychoroid group (p = 0.04). 36 (28.8%) eyes in pachychoroid and 60 (48%) eyes in non-pachychoroid group had spontaneous resolution of CSC (p = 0.007). A total of 39 (31.2%) eyes in pachychoroid and 13 (10.4%) in non-pachychoroid group had recurrent CSC at the end of follow-up. CONCLUSION: CSC eyes with pachychoroid had more recurrent episodes and less spontaneous resolution compared to CSC eyes in non-pachychoroid group. Final visual acuity was worse in eyes with CSC and pachychoroid. These findings need to be validated in a larger sample size with a prospective study design.
