Hypertension as a Risk Factor for Primary Open-angle Glaucoma: A Meta-analysis.

Hypertension (HTN) is not recognised as an independent risk factor for primary open-angle glaucoma (POAG). A search of PubMed, Embase, Medline, Wanfang, and Cochrane Library databases from the time each database was established up to July 2022 was performed. All studies were pooled and assessed for heterogeneity and the quality of the literature. Five cross-sectional studies were included in the meta-analysis with 1144 individuals with POAG and 29, 373 without POAG. The combined analysis found that the incidence of HTN was higher among the individuals with POAG than among those without (OR 1.55; p <0.001). There was also a significant difference in the incidence of diabetes among individuals with POAG compared with those without (OR: 1.31; p=0.002). A meta-analysis of cross-sectional studies revealed that the incidence of HTN and diabetes was significantly greater among individuals with POAG. HTN and diabetes were found to be independent risk factors for POAG. Key Words: Primary open-angle glaucoma (POAG), Hypertension (HTN), Diabetes, Meta-analysis.
