  • PRP = panretinal photocoagulation.

  • According to the Wisconsin grading system.

  • Classified according to the mean urinary albumin excretion rate of three separate 24 hour urine collections: no nephropathy, <20 μg/min; incipient nephropathy, 20–200 μg/min; overt nephropathy, >200 μg/min.

  • Diagnosis made on the basis of food pulse status, measurement of ankle pressure index, electrocardiogram, history of angor pectoris plus abnormal ergometry or previous myocardial infarction. Three patients with coronary heart disease (CHD) undergoing PRP and two patients with CHD not undergoing PRP also presented arterial occlusive disease.
