PURPOSE: To investigate whether patients who developed chronic central serous chorioretinopathy (cCSC) in association with corticosteroid treatment respond differently to photodynamic therapy (PDT) as compared to patients who have not used corticosteroids. METHODS: Clinical evaluation included visual acuity (VA), fundoscopy, optical coherence tomography (OCT), fluorescein and indocyanine green angiography. The main outcome measure was a complete resolution of subretinal fluid (SRF) on OCT after PDT. RESULTS: One hundred and twenty-three eyes (117 patients), including 35 steroid-associated cases (29%), who received PDT treatment with reduced settings for active cCSC were included. Complete resolution of SRF on OCT was seen in 69% of the steroid-associated cases and in 50% of the controls after PDT treatment (p = 0.062). At the final follow-up moment, 74% of the cases had a complete resolution of SRF compared to 60% in the control group (p = 0.142). The VA at the first visit after therapy showed an increase in both groups (mean VA before treatment; cases: 69 +/- 14 Early Treatment Diabetic Retinopathy Study (ETDRS) letters, controls: 74 +/- 13 ETDRS letters, mean VA first visit after treatment; cases: 76 +/- 13 ETDRS letters, controls: 75 +/- 13 ETDRS letters). No significant differences were seen in response to PDT between the patients who continued corticosteroid treatment and those who ceased the use of corticosteroids. CONCLUSIONS: Photodynamic therapy appears to be equally effective in patients suffering from steroid-associated cCSC as compared to patients with cCSC who do not use corticosteroids. Continuation of corticosteroids at the time of PDT treatment does not seem to adversely affect PDT response.
