Micronutrients and diabetic retinopathy a systematic review.

We have evaluated the evidence for the association between intake and blood levels of micronutrients and diabetic retinopathy. Treatment for diabetic retinopathy requires significant clinical input and specialist ophthalmologic care. Micronutrients, including vitamin C, vitamin E, and magnesium, may interfere with pathologic mechanisms of diabetic retinopathy and potentially alter its risk.
