The presence of retinopathy in patients with secondary diabetes following pancreatectomy or chronic pancreatitis.
The incidence of diabetic retinopathy was evaluated by means of fluorescein angiography in 54 patients with diabetes secondary to chronic pancreatitis or to pancreatectomy. Thirty-one percent of the patients had background retinopathy; none had proliferative retinopathy. The percentage of patients with retinopathy was the same in groups with or without a family history of diabetes. There was no correlation between the degree of metabolic control, the levels of C-peptide, glucagon, growth hormone, and the presence of retinopathy. Retinopathy was correlated with the duration of diabetes. In conclusion, diabetes caused by pancreatitis or pancreatectomy has a significant prevalence of retinopathy, which has more benign characteristics and slower evolution than the retinopathy in patients with primary diabetes.
