Choroidal Thickness Change in Central Serous Chorioretinopathy after Photodynamic Therapy Using Optical Coherence Tomography

Objective: This study aimed to evaluate the change in choroidal thickness and subanalyze Haller’s and Sattler’ layer in patientswith central serous chorioretinopathy (CSC) following low-fluence photodynamic therapy (PDT) using enhanced depth imagingoptical coherence tomography (EDI-OCT).Methods: In this retrospective study, medical records of the patients with CSC were reviewed. Patients with a diagnosis of CSC anda history of decreased visual acuity for more than six months and treated with half-dose PDT with verteporfin were included in thestudy. Patients who received previous PDT for chronic CSC or had evidence of choroidal neovascular membrane were excluded.Main outcome measures were the change in choroidal thickness and subanalysis of Haller and Sattler layer after treatment.Results: A total of 13 eyes of 13 patients were included in the study. The mean age of the patients was 49±11 years (range 40–68).The mean subfoveal choroidal thickness decreased significantly from 310.60±89.16 μm at baseline to 308.41±90.03 μm after PDT(p
