To describe the laboratory findings of diabetic patients without diabetic retinopathy and with proliferative diabetic retinopathy and compare the results between each other.
It is a retrospective, observational, transversal, and comparative study. We analyzed the results of preoperative tests of 200 patients; 124 of who were diagnosed with cataract and had no diabetic retinopathy (NDR), and who underwent cataract surgery; the other 76 had proliferative diabetic retinopathy (PDR) and underwent vitrectomy.
A statistical significant diference was determined for the following variables: age of diagnosis, years of diagnosis, protrombin time, hemoglobin, hematocrit, platelets, urea, creatinine, cholesterol, urinary proteins and potassium. The most significant variables for predicting PDR were years of diagnosis, creatinine and urinary proteins. Using all significant variables PDR can be predicted in 85.4% of cases.
Mexican diabetic patients show a poor glycemic control done in primary care institutions. Patients with proliferative diabetic retinopathy are an economically active population and probably have some degree of renal failure. Primary care physicians will be able to refer the patients for an earlier detection of they can determine the probability of the disease.
