Comparison of choroidal thickness between central serous choroidopathy and polypoidal choroidal vasculopathy

Abstract

AbstractPURPOSE: To compare choroidal thicknesses among eyes with polypoidal choroidal vasculopathy (PCV), and central serous chorioretinopathy (CSC). METHODS: Patients with PCV and CSC underwent enhanced depth imaging optical coherence tomography (EDI OCT). A horizontal linear section comprising 100 averaged scans was obtained of each macula. The choroidal thickness was measured from the outer border of the retinal pigment epithelium to the inner scleral border. Seventeen healthy subjects (17 eyes) also underwent EDI OCT. RESULTS: A total of 17 eyes of 17 consecutive patients with CSC (17 male, mean age 50 years range 37‐66 years) and 15 eyes of 15 patients with PCV were included in the analysis (8 male, mean age 69 years range 57‐73 years). Mean choroidal thickness was 437 µm ± 97 µm in patients with CSC and mean choroidal thickness was 335 µm ± 53 µm in patients with PCV. The choroid was thicker in PCV and CSC patients than in controls(mean age 62 years range 55‐72, 219 ± 35 µm p<0.005). However, there was significant difference in mean subfoveal choroidal thickness between CSC and PCV (p<0.005) . CONCLUSION: The choroid was thicker in eyes with PCV or CSC than in control
