Purpose: To identify characteristics of Caucasian chronic central serous chorioretinopathy (cCSC) patients without a complete resolution of subretinal fluid (SRF) after reduced-settings photodynamic therapy (PDT), or with a recurrence of SRF after PDT.
Methods: Chronic CSC patients treated with reduced-settings PDT were divided into a successful PDT group and unsuccessful PDT group. Patients in the successful PDT group did not have any subretinal fluid (SRF) during follow-up after PDT, whereas the unsuccessful PDT group was categorized based on either persistence or recurrence of SRF after PDT treatment. Data on age, sex, best-corrected visual acuity (BCVA), PDT spot size, characteristics on fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT) were obtained.
Results: Twenty-six patients in the successful PDT group (20 males, 6 females) had a mean age of 51 years (range, 25-78). In the unsuccessful PDT group, 20 males with a mean age of 60 years (range, 34-78) were included. At last visit before PDT, age, percentage of males, and percentage of patients with diffuse leakage > 1 optic disc diameter on FA were higher in the unsuccessful PDT group (p = 0.010, p = 0.029, and p = 0.008, respectively). At last visit before PDT, BCVA and the percentage of patients with intense hyperfluorescence on ICGA were lower in the unsuccessful group (p = 0.017 and p = 0.004, respectively). Patients with intense hyperfluorescence on ICGA were more likely (95% CI 1.3-333 times) to have a successful outcome (p = 0.045). A decrease in SFCT at final visit was observed in both groups (- 111 μm and p = 0.013, and - 141 μm and p = 0.007, respectively). BCVA only improved at final visit in the successful PDT group (5 Early Treatment of Diabetic Retinopathy Study letters, p < 0.001).
Conclusions: Chronic CSC patients with recurrent or persistent SRF after PDT are characterized by a higher percentage of males, more patients with diffuse leakage on FA, more patients without intense hyperfluorescence on ICGA, higher age, and lower pre-PDT and long-term BCVA than in the successful PDT group. A reduction in SFCT after PDT does not necessarily lead to complete resolution of SRF, while a resolution of SRF appears to be required to lead to a significant BCVA improvement in cCSC.
