Dhirani NA, et al. - Researchers probed into the short- and long-term outcomes of half-dose verteporfin with photodynamic therapy (PDT) in the treatment of chronic central serous retinopathy (CSR). In a Canadian cohort, half-dose PDT was discovered to be an effective treatment option for chronic CSR. It was both safe and durable. The positive treatment effect was found rapidly. It was noted that the initial 6-week finding was highly associated with the final follow-up result.
