ABSTRACT

Background. Although risk factors for worsening of diabetic retinopathy are known, it is necessary for the physician who treats diabetes to know which factors require special care whenever photocoagulation is needed. Risk factors with higher than recommended values were identified, in order to estimate the need of additional therapy. Methods. We identified retrospectively in patients undergoing photocoagulation: glycemia (fasting and postprandial), glycated hemoglobin, blood pressure (systolic, mean, diastolic) arterial hypertension history. The rate of patients with glycemia or arterial hypertension above recommendations was determined, and the variables were compared in patients who developed visual loss and severe visual loss (SVL, visual capacity › 20/200) and those who did not by χ². Results. 81 eyes of 50 patients (mean age 60.5), 29 females (58%). Diabetes duration mean was 17 years; 37 patients had arterial hypertension history. 54% of patients had systolic hypertension, 64% diastolic hypertension, 60% fasting hyperglycemia, 64% postprandial hyperglycemia and 69% glycated hemoglobin › 7%. 63 eyes did not have SVL before photocoagulation, 4 developed it (6.3%). There was no difference among variables of patients who developed SVL and those who did not. Discussion. Most patients treated with photocoagulation required additional control of glycemia and arterial hypertension. There were no statistical differences among patients with and without SVL because the prevalence of the latter was low. It is suggested to increase postprandial glycemia and arterial hypertension control in patients undergoing photocoagulation.
