Primary open-angle glaucoma, intraocular pressure, and diabetes mellitus in the general elderly population. The Rotterdam Study.
OBJECTIVE
To investigate the association of primary open-angle glaucoma and intraocular pressure (IOP) with newly diagnosed diabetes mellitus.


METHODS
Subjects participating in the Rotterdam Study (n = 4178; ages, 55 years and older) were examined according to standard protocols, including a medical history interview, perimetry, applanation tonometry, funduscopy, and a nonfasting glucose tolerance test. Glaucoma was defined by the presence of a glaucomatous visual field defect. A distinction was made between high-tension glaucoma and normal-tension glaucoma. The relation of glaucoma and IOP with newly diagnosed diabetes mellitus and blood glucose was analyzed using regression analysis.


RESULTS
The presence of diabetes mellitus was associated with an overall rise in mean IOP of both eyes of 0.31 mmHg (95% confidence interval, 0.12-0.50), and with a threefold increased presence of high-tension glaucoma (odds ratio, 3.11; 95% confidence interval, 1.12-8.66). A 10-mmol/l higher random serum glucose level was borderline significantly associated with a mean IOP that was, on average, 0.41 mmHg (95% confidence interval, -0.02-0.84) higher and with an odds ratio of 2.82 (95% confidence interval, 0.92-8.58) for high-tension glaucoma. A 10-mmol/l rise in serum glucose on a glucose tolerance test was associated with an overall rise of mean IOP of 0.59 mmHg (95% confidence interval, 0.26-0.92) and with an odds ratio of 1.88 (95% confidence interval, 0.81-4.32) for high-tension glaucoma.


CONCLUSIONS
Newly diagnosed diabetes mellitus and high levels of blood glucose are associated with elevated IOP and high-tension glaucoma.
