Uncontrolled Hypertension Is Common in Glaucoma Clinics

BACKGROUND: To determine the magnitude of uncontrolled hypertension and smoking among patients visiting an eye clinic, and ascertain if referral to care providers is effective. METHODS: Information on smoking status and blood pressure (BP) was collected among patients ≥18 years visiting an eye clinic. Those with high BP (systolic: ≥140 mm Hg and/or diastolic: ≥90 mm Hg) received a pamphlet on harms of hypertension on vision and were referred to a primary care physician. Smokers received a pamphlet on negative effects of smoking on vision and were offered referral to a tobacco quitline. Patients were followed up for referral outcome within 10 weeks from screening. RESULTS: Screening: A total of participants screened included 140 (29.5%) with high BP and 31 (6.6%) current smokers. In the high BP group, 92 (66%) subjects were previously diagnosed with hypertension. Follow-up: Of the 140 participants with elevated BP, 84 (60%) responded to follow-up. Among these 84 participants, 57 (67.9%) had consulted primary care, of whom 5 (8.8%) reported being newly diagnosed with hypertension, and 11 (19.3%) reported a change in their antihypertensive prescription. Among the 31 smokers, 24 (77.4%) were willing for quitline referral. Sixteen (66.7%) of these patients responded to follow-up, 8 (50%) of whom reported participation in a smoking-cessation program with 1 patient (6.3%) successfully quitting smoking. CONCLUSIONS: Nearly one-third of patients attending an eye clinic had elevated BP, and a smaller, but substantial, number of patients were current smokers. Eye clinics may serve as point for identification and referral of these patients with unmet needs.
