A retrospective case-control study compared 100 ocular hypertensive patients with 100 ocular normotensive patients matched for sex and age. Interviews were conducted and charts were reviewed to explore demographic, personal, and environmental factors, as well as medical history and refractive error. Multiple logistic regression analyses assessed which factors were independently related to the presence or absence of ocular hypertension. The variables significantly associated with the presence of ocular hypertension were family history of glaucoma, myopic refractive error, absence of liquor intake, history of nonocular surgery, high income, and history of high BP.
