To examine the cross-sectional relationship between blood pressure, perfusion pressure, and prevalence of open angle glaucoma (OAG) in an adult Latino population.
Participants aged 40 years and older (N = 6130) from the Los Angeles Latino Eye Study (LALES), a large, population-based study of self-identified adult Latinos, underwent an interviewer-administered questionnaire and a complete ocular and clinical examination. Logistic regression was used to evaluate the covariate-adjusted association of OAG with systolic, diastolic, and mean blood pressures and perfusion pressures. Covariates included age, intraocular pressure, history of glaucoma treatment including medications and surgery, and history of blood pressure and treatment of blood pressure including use of medications.
Low systolic (odds ratio [OR] = 2.5), diastolic (OR = 1.9), and mean (OR = 3.6) perfusion pressures and low diastolic blood pressure (OR = 1.9) were associated with a higher prevalence of OAG in LALES participants. Higher systolic blood pressure and mean arterial blood pressure were associated with a higher prevalence of OAG. There was no relationship between the prevalence of OAG and the presence of a history of cardiovascular disease.
Low diastolic, systolic and mean perfusion pressures, low diastolic blood pressure, and high systolic and mean arterial blood pressures are associated with a higher prevalence of OAG in adult Latinos.
