Some studies have shown that significant caffeine intake over a short period of time can slightly elevate intraocular pressure (IOP). However, other studies indicate that caffeine has no meaningful impact on IOP. People with glaucoma should limit caffeine intake to moderate levels.
Medical research hasn't shown that any type of food or diet affects glaucoma. Common sense suggests that eating a balanced diet, not smoking, and staying at a healthy weight will help keep you at your best. Please talk with your doctor before introducing a multivitamin or multimineral nutritional supplement to your diet.
Oral carbonic anhydrase inhibitors are better tolerated if taken with a glass of milk about 20 minutes before meals or bedtime. Side effect of eye drops can be reduced by appropriate nasolacrimal occlusion (finger pressure over the tear duct after taking the drops).
A healthy diet coupled with a daily routine of exercise is a good prescription for everyone interested in good health. But remember, every patient is different. Before making any drastic change in your diet, it is wise to communicate that intention to your doctor and discuss the pros and cons. The same advice is true for embarking on a new exercise program. While studies show that aerobic exercise can lower intraocular pressure, other forms of exercise can increase pressure. So, if you're a glaucoma patient, it's especially important to check with your doctor before making any lifestyle changes. Such changes could have an impact on the test results your doctor relies on to evaluate the success of your treatment plan.
