Kim JS, Kim YK, Kim YW, et al. - Researchers intended to determine if there is an association between strabismus and primary open-angle glaucoma (POAG) in a representative Korean population. In total, 11,114 candidates aged 20 years or older in the Korea National Health and Nutrition Examination Survey database for the years 2010 through 2011 have been reviewed. According to the International Society of Geographical and Epidemiological Ophthalmology criteria, glaucoma diagnosis was based on fundus photography and frequency-doubling technology perimetry results. Esodeviation was independently linked to POAG in the Korean population. This might be the result of, at least in part, ocular-adduction-induced greater strain on the temporal optic nerve head and peripapillary tissues, which makes eyes with esodeviation more susceptible to POAG.
