Abstract:
AIMS: To identify single-nucleotide polymorphisms (SNPs) associated with central serous chorioretinopathy (CSCR) by a systematic review and meta-analysis, and to compare the association profiles between CSCR, neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV). METHODS: We searched the EMBASE, PubMed and Web of Science for genetic studies of CSCR from the starting dates of the databases to 12 September 2020. We then performed meta-analyses on all SNPs reported by more than two studies and calculated the pooled OR and 95% CIs. We also conducted sensitivity analysis and adopted the funnel plot to assess potential publication bias. RESULTS: Totally 415 publications were reviewed, among them 10 were eligible for meta-analysis. We found 10 SNPs that have been reported at least twice. Meta-analysis and sensitivity analysis confirmed significant associations between CSCR and six SNPs in three genes, namely age-related maculopathy susceptibility 2 (
ARMS2) (rs10490924, OR=1.37; p=0.00064), complement factor H (
CFH) (rs800292, OR=1.44; p=7.80×10-5; rs1061170, OR=1.34; p=0.0028; rs1329428, OR=1.40; p=0.012; and rs2284664, OR=1.36; p=0.0089) and tumour necrosis factor receptor superfamily, member 10a (
TNFRSF10A) (rs13278062, OR=1.34; p=1.44×10-15). Among them, only
TNFRSF10A rs13278062 showed the same trend of effect on CSCR, nAMD and PCV, while the SNPs in
ARMS2 and
CFH showed opposite trends in the SNP associations. CONCLUSIONS: This study confirmed the associations of
ARMS2,
CFH and
TNFRSF10A with CSCR, and revealed that
ARMS2,
CFH and
TNFRSF10A may affect different phenotypic expressions of CSCR, nAMD and PCV.
