Does postmenopausal hormone replacement therapy affect intraocular pressure?

PURPOSE: To assess the effects of postmenopausal hormone replacement therapy (HRT) on intraocular pressure (IOP). PATIENTS AND METHODS: This was a cross-sectional controlled study, including 107 women aged 60 to 80 years receiving HRT and 107 controls who have never received HRT. All subjects underwent IOP assessment and funduscopic photography for cup-to-disc (C/D) ratios, and completed questionnaires regarding personal and family history of glaucoma, hormone replacement therapy, lifetime estrogen and progesterone exposure, and cardiovascular risk factors. Main Outcome Measures included IOP, prevalence of increased IOP, and C/D ratios. RESULTS: The groups did not differ in mean IOP (15.3 versus 15.3 mm Hg), mean vertical (0.18 versus 0.21) and horizontal (0.17 versus 0.14) C/D ratios, and in prevalence of increased IOP (15% versus 14%), C/D ratio (7% versus 7%), or glaucoma (9% versus 11%). A personal history of ischemic heart disease was the only risk factor associated with increased IOP (O.R. = 4.63, P = 0.003). Lifetime estrogen and progesterone exposure, including pregnancies, deliveries, menstruation years, and the use of oral contraceptives did not significantly affect the risk for increased IOP. CONCLUSION: Hormone replacement therapy and lifetime estrogen and progesterone exposure do not seem to affect IOP or the risk for increased IOP. A personal history of ischemic heart disease may be associated with a higher risk for this disorder.

The effect of hormone therapy on the risk for age-related maculopathy in postmenopausal women.

OBJECTIVE: To evaluate the effect of postmenopausal hormone therapy (HT) as well as the use of oral contraceptives and lifetime endogenous hormone exposure on the risk for age-related maculopathy (ARM) in postmenopausal women. DESIGN: This was a cross-sectional, controlled study. A total of 102 women from 60 to 80 years of age who were receiving HT and 100 controls underwent a detailed clinical funduscopic evaluation and stereoscopic fundus photography for the presence and grading of ARM. All participants completed a standardized questionnaire regarding vascular risk factors, HT, and lifetime exogenous and endogenous estrogen and progesterone exposure. Statistical analysis was performed using Student's t test, chi2 test, and a multivariate logistic regression model. RESULTS: The HT and the non-HT groups did not differ in terms of early (11% v 15%), late (6% v 6%), or wet (2% v 2%) ARM prevalence rates. Women with ARM were significantly older than controls (69 v 66 years; P = 0.001, 95% CI = 0.008 - 0.027) and were more likely to have ischemic heart disease (21% v 9%; OR = 2.86, P = 0.03, 95% CI = 0.020 - 0.360). Lifetime exogenous and endogenous hormone exposures and other cardiovascular risk factors were not significantly different among women with ARM as compared with controls. CONCLUSION: Postmenopausal HT may not affect the risk for either early or late ARM in women aged 60 to 80 years. The risk for both entities is not necessarily affected by either exogenous or endogenous lifetime hormone exposure. A history of ischemic heart disease may be associated with an increased risk for ARM.
