Smokers and diabetic maculopathy

Of 200 examined diabetic patients with diabetic maculopathy there were 27 smokers, 23 of them diabetics of type II. In comparison with the control group of 23 diabetics with diabetic maculopathy-nonsmokers, the smokers showed a significantly higher incidence of the ischemic type of diabetic maculopathy which, however, did not manifest itself more markedly in their visual acuity.
