The Association Between Circulating Sex Hormones and Central Serous Chorioretinopathy: A Case-Control Study
Abstract
Background: Central serous chorioretinopathy (CSC) is preferential cocurated in males, however the associations between sex hormones and CSC incidence or progression remains unclear. The sex hormone concentration assessments in CSC cases and healthy controls will update the knowledge in CSC management.
Methods: This case-control study included 59 CSC cases and 30 healthy controls, from January 2019 to December 2020. The CSC cases would be defined as spontaneous resolved if the subretinal fluid were absorbed within three months. The concentrations of total testosterone (TT), free testosterone (FT), estradiol (E2), sex hormone-binding globulin (SHBG), progesterone, leuteinizing hormone (LH) and dehydroepiandrosterone sulfate (DHEA-S) were detected in all the participants. The relationships between sex hormone concentrations and CSC-related characteristics were analyzed with Pearson correlation analyses.
Results: Significantly increased TT, FT, FT/E2 ratio, SHBG concentrations as well as decreased DHEA-S level were detected in non-resolved CSC group compared with the control group. Comparing with the resolved ones, it was found that TT, FT and SHBG concentrations were increased in the non-resolved CSC. A significant positive correlation between TT concentrations and CMT (R2=0.168, P=0.031) as well as SRF height (R2=0.146, P=0.045) were detected in the non-solved CSC group.
Conclusion: Different concentrations of TT, FT, FT/E2 ratio, DHEA-S and SHBG were detected in resolved and…
How strong is the evidence?
Evidence Hub reads this as a case-control. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
