Metformin can reduce risk of open-angle glaucoma in people with diabetes

In continuation of my update on metformin

Taking the medication metformin hydrochloride was associated with reduced risk of developing the sight-threatening disease open-angle glaucoma in people with diabetes, according to a study published online by JAMA Ophthalmology.

Medications that mimic caloric restriction such as metformin can reduce the risk of some late age-onset disease. It is unknown whether these caloric mimetic drugs affect the risk of age-associated eye diseases such as macular degeneration, diabetic retinopathy, cataract or glaucoma.

Researcher Julia E. Richards, Ph.D., of the University of Michigan, Ann Arbor, and co-authors examined metformin use and the risk of open-angle glaucoma (OAG) using data from a large U.S. managed care network from 2001 through 2010.

Of 150,016 patients with diabetes, 5,893 (3.9 percent) developed OAG. Throughout the study period, 60,214 patients (40.1 percent) filled at least one metformin prescription; 46,505 (31 percent) filled at least one sulfonylurea prescription; 35,707 (23.8 percent) filled at least one thiazolidinedione prescription; 3,663 (2.4 percent) filled at least one meglitinide prescription; and 33,948 (22.6 percent) filled at least one insulin prescription. Some patients filled prescriptions for multiple medications.
