Abstract

Purpose : To evaluate the phenotype and genotype correlation of central serous chorioretinopathy (CSC) patients with or without irregular pigment epithelial detachment (PED) on SD-OCT.

Methods : This study is a retrospective observational study including a total of 618 patients with CSC, typical choroidal neovascularization (CNV), and polypoidal choroidal vasculopathy (PCV). For CSC patients, a flat, irregular non-dome-shaped protrusion of RPE with sub-RPE fluid on OCT was defined as an irregular PED. Only irregular PED with at least partially hyper-reflective sub-RPE fluid was defined as a ’definite irregular PED’. CSC without definite irregular PED included cases with regular PED, irregular PED with hypo-reflective sub-RPE fluid, or with indeterminate optical density, RPE bump, and only SRF. Participants were classified into 5 subgroups; 1) total CSC (n=280) 2) CSC with definite irregular PED (n=126) 3) CSC without definite irregular PED (n=154) 4) typical CNV (n=203) and 5) PCV (n=203). Ten known major AMD-associated SNPs were analyzed. Logistic regression analysis was performed to reveal the age, sex adjusted association between each pair of subgroups. Individual tests for 10 SNPs were considered significant at P<0.005 (Bonferroni correction).

Results : Association analysis between CSC without definite irregular PED and CNV revealed that significant difference for rs10490924 in ARMS2 (P=1.45*10-3), rs10737680 in CFH (P=3.65*10-3), and marginally significant difference for rs800292 in CFH. Between CSC without definite irregular PED and PCV, rs10490924, rs10737680, and rs800292 were significantly different (P=8.35*10-6, P=3.16*10-3, and P=4.91*10-3, respectively). In contrast, association analysis between CSC with definite irregular PED and CNV revealed no SNP showing significant difference. Between CSC with definite irregular PED and PCV, only 1 SNP (rs10490924) was significantly different (P=4.17*10-3). Association analysis between CSC with definite irregular PED and CSC without definite irregular PED revealed that significant difference for rs800292 (P=2.00*10-3), and marginally significant difference for rs10737680.

Conclusions : These findings suggest patients with definite irregular PED are genetically different from those without definite irregular PED and may have genetic and pathophysiologic overlap with AMD patients.
