摘要

Purpose

To evaluate the correlation between spectral-domain optical coherence tomography (SD-OCT), fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) findings and recurrence following photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC).

Methods

We retrospectively reviewed medical records of 68 eyes from 68 patients diagnosed with cCSC and treated with PDT. Demographic data, duration of symptoms before treatment, baseline best-corrected visual acuity (BCVA), and multimodal imaging features (SD-OCT, FFA, ICGA) were analyzed. Patients were followed up to 24 months post-PDT for recurrence.

Results

The mean age was 48.1 ± 10.4 years; 76.5% were male. Recurrence was observed in 19 patients (27.9%). Longer symptom duration before PDT (20.9 vs 13.3 months, p = 0.001), presence of non-shallow PED on SD-OCT (68.4% vs 38.8%, p = 0.02), and RPE changes on fundoscopy (94.7% vs 71.4%, p = 0.03) were significantly associated with recurrence. No significant correlation was found with FFA or ICGA findings.

Conclusion

Longer symptom duration and certain SD-OCT and fundus features may predict recurrence after PDT in cCSC. Recognizing these predictors could help guide earlier treatment decisions.
