OBJECTIVE
This study was performed to determine risk factors for central serous chorioretinopathy (CSC) in pregnant women.
METHODS
This retrospective observational study was performed in a cohort of all 1881 women giving birth at a single center. The hospital database was searched to abstract all women diagnosed with pre-eclampsia (PE) as well as those visiting the eye clinic during the current pregnancy. Medical chart review was performed in all women diagnosed with CSC and PE.
RESULTS
PE developed in 73 (3.9%) women, six (8.2%) of whom visited the eye clinic for problems occurring in the current pregnancy; 47 of 1808 (2.6%) women without PE visited the eye clinic (P = 0.015). Four women were identified as having developed CSC after onset of PE, and none of those without PE developed CSC (5.5% [4/73] vs 0.0% [0/1808], respectively, P < 0.0001). Stepwise regression analysis selected four risk factors for CSC: hematocrit value > 38.0% (odds ratio [OR], 22.9; 95% confidence interval [CI], 2.12-247), serum creatinine > 0.7 mg/dL (OR, 21.7; 95%CI, 1.12-422), time interval from diagnosis of PE until delivery > 14 days (OR, 20.0; 95%CI, 1.87-214), and urine protein : creatinine ratio (mg/mg) > 4.5 (OR, 15.7; 95%CI, 0.81-304). Hematocrit value > 38.0% was finally identified as the only independent risk factor (OR, 22.9; 95%CI, 2.12-1716) for CSC in PE women.
CONCLUSIONS
CSC was likely to occur in PE women, especially in those with hemoconcentration as a result of plasma leakage from the circulating blood due to increased vascular permeability.
