Diabetic retinopathy, which can lead to progressively blurred vision, is a real concern for diabetes patients. In truth, only 6% of those with diabetes will lose their vision entirely because blindness in diabetics is largely treatable. Changes in diet and lifestyle can help control both diabetes and diabetic retinopathy.
Those with diabetic retinopathy are much more susceptible to dry eye symptoms. Diabetics have decreased tear break-up time, which indicates poor tear film stability. A review of a number of studies on diabetic retinopathy and its effects published in the Expert Review of Ophthalmology states that “patients whose dry eye symptoms worsened tended to be those whose serum glucose was poorly controlled.” Get more information on how to treat dry eye syndrome naturally.
