Spanish study finds POAG prevalence similar to other studies in whites

The prevalence of primary open-angle glaucoma in a southern Spanish population was similar to estimates found in other studies of predominantly white populations, according to a study.

Alfonso Anton, MD, and colleagues conducted a cross-sectional, population-based epidemiologic study of residents of Segovia, Spain, to determine the prevalence of primary open-angle glaucoma (POAG). The researchers randomly selected 569 subjects between the ages of 40 and 79. The diagnosis of POAG was established when any eye had an open angle and a glaucomatous optic nerve and glaucomatous visual field verified by two independent observers.

The prevalence of POAG was 2.1% and of ocular hypertension 1.7%. The prevalence of POAG increased with age and tended to be greater in men than women, the researchers found.

The study is published in the October issue of Journal of Glaucoma.
