Abstract
OBJECTIVES: We describe the real-world outcomes of photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSCR) in a single centre over nine years. METHODS: We carried out a retrospective analysis of patients with chronic CSCR who received half dose PDT in a single centre between 2011 and 2019. Visual acuity (VA) and retinal thickness (RT) was recorded between baseline visit and first recorded review visit. RESULTS: We included 125 eyes of 113 patients in this study. Mean age at treatment was 55.0 ± 12.1 years, with a higher male predominance (83 men, 30 women). Mean baseline VA was 0.40 ± 0.31 logMAR with a mean visual outcome gain post-PDT of 0.05 logMAR (p = 0.005). Mean baseline RT was 390 ± 82 microns with a mean reduction of RT post-PDT of 66 microns (p < 0.001). 17.6% of eyes were treated for recurrent CSCR. CONCLUSION: We found overall a mean improvement in VA and structural outcomes after PDT. In the absence of randomised clinical trials this study supports the use of half dose PDT for treatment of chronic CSCR.
