A 10-Year Study of Central Serous Chorioretinopathy: Recurrence Rate and Factors affecting Recurrence

Purpose: To determine the recurrence rate of central serous chorioretinopathy and risk factors responsible for recurrence. Methods: The study was designed as a hospital-based retrospective study. Medical records of all patients with CSCR, seen at the retina clinic from January 1999 to December 2008, were retrospectively analyzed. Univariate and multivariate analysis were done using statistical package for social sciences (SPSS). Results: The recurrence rate of CSCR in 752 patients was 19.41%. The mean attack rate was 1.29. Using the Wilcoxon signed ranks test, it was found that in patients with and without recurrence, there was a significant improvement in visual acuity after treatment. Univariate analysis done, to study the association between risk factors and recurrence of CSCR, showed that patients aged less than 40 and the male sex were significantly associated with recurrence of CSCR. Multivariate logistic regression analysis showed the same two factors to be significantly associated with recurrence of CSCR. 8.37% patients had bilateral CSCR. Conclusion: The recurrence rate of CSCR in 752 patients, with an average follow-up of 12.11 months was 19.41%. Patients aged less than 40 years had a 1.59 times increased risk of recurrence. Patients of the male sex had a 1.96 times increased risk of recurrence.
