Family History in the Primary Open-Angle African American Glaucoma Genetics Study Cohort.

ABSTRACT: PURPOSE:To determine the relationship between positive family history (FH) and primary open-angle glaucoma (POAG) diagnosis and clinical presentation in the Primary Open-Angle African American Glaucoma Genetics (POAAGG) cohort. METHODS:FH of POAG in first-degree relatives was assessed in 2365 subjects in the POAAGG cohort. A standardized interview was used to assess FH of glaucoma, demographic characteristics, lifestyle choices, and medical and ocular comorbidities. RESULTS:Positive FH was associated with increased risk of POAG (age-adjusted odds ratio and 95% confidence interval 3.4 [2.8, 4.1]). In age-adjusted analysis among POAG cases, positive FH was associated with younger age (P < .001), female sex (P < .001), hypertension (P = .006), use of hypertension medication (P = .03), and prior glaucoma surgery (P = .02). Cases with positive FH also had thicker retinal nerve fiber layers (P = .03). CONCLUSIONS:The risk conferred by positive FH suggests strong genetic underpinnings for some patients with this disease, which will be investigated by genome-wide association studies and whole exome sequencing.
