This study compared the efficacy and safety of crossover treatment between half-dose photodynamic therapy (PDT) and eplerenone treatment in patients with chronic central serous chorioretinopathy (cCSC). The results showed that half-dose PDT was more effective in resolving subretinal fluid (SRF) and improving foveal sensitivity compared to eplerenone treatment after the failure of primary treatment.
Purpose: To compare the efficacy and safety of crossover treatment to half-dose photodynamic therapy (PDT) and eplerenone treatment after the failure of primary treatment in patients with chronic central serous chorioretinopathy (cCSC). Design: Multicenter crossover clinical trial. Subjects: At 3 months after the baseline visit of the SPECTRA (Half-Dose Photodynamic Therapy Versus Eplerenone: Treatment Trial for Chronic Central Serous Chorioretinopathy) randomized controlled trial, either half-dose PDT or eplerenone treatment was evaluated for each patient, and patients who still demonstrated subretinal fluid (SRF) were included in the current study, the SPECS (Central Serous Chorioretinopathy Treated with Half-Dose PDT or Eplerenone Crossover Study) trial. Methods: At the baseline visits for the current SPECS trial, crossover treatment was performed for patients who still demonstrated SRF. These patients received either half-dose PDT or oral eplerenone for 12 weeks. Both anatomic and functional parameters were evaluated 3 months after crossover treatment. Main Outcome Measures: Complete resolution of SRF on OCT. Results: Forty-nine patients were included in the SPECS trial (38 received primary eplerenone treatment; 11 received half-dose PDT). At 3 months after crossover treatment, 32 of 37 (86.5%) in the crossover to half-dose PDT group and 2 of 9 (22.2%) in the crossover to eplerenone group had complete SRF resolution (P = 0.030). The mean foveal sensitivity increased significantly more in the crossover to half-dose PDT group (mean, +3.08 dB) compared with the crossover to eplerenone group (mean, -0.27 dB; P = 0.009). Conclusions: Patients with cCSC with the persistence of SRF after primary eplerenone treatment can benefit from half-dose PDT, which can induce a relatively fast and complete SRF resolution, along with an improvement in foveal sensitivity.
