RESUMEN
OBJECTIVE: The aim of this study was to determine the prevalence of open angle glaucoma in first-degree relatives accompanying POAG patients during routine examination in a reference hospital. METHOD: First-degree relatives of primary open angle glaucoma patients who accompanied their relatives to the glaucoma service of a reference hospital were screened for glaucoma. RESULTS: One-hundred and one first-degree relatives were examined, of which 56.4 percent had never had their intraocular pressure measured. 10.9 percent had previously been diagnosed with glaucoma, and 5.9 percent were newly diagnosed during this study. CONCLUSIONS: The eye examination of first-degree relatives identified a significant percentage of individuals with glaucoma. Despite being first-degree relatives of glaucoma patients, 56.4 percent of the companions had never had their eye pressure measured, demonstrating a lack of awareness about this disease.
