Lancet - RAS Inhibitors to Prevent Diabetic Retinopathy

"Effects of RAS inhibitors on diabetic retinopathy: a systematic review and meta-analysis"

"Interpretation

In patients with diabetes, RAS inhibitors reduce the risk of diabetic retinopathy, and increase the possibility of diabetic retinopathy regression. ACE inhibitors might be better than ARBs for treating diabetic retinopathy, and might exert the most beneficial effect on diabetic retinopathy of all widely used antihypertensive drug classes.
