RESUMO
BACKGROUND: The most common complication after vitrectomy is the rebleeding in vitreous cavity. It is important to detect the different factors that can increase the vitreous rebleeding rate in these patients. OBJECTIVE: To carry out a retrospective review of the rate of vitreous rebleeding after vitrectomy or phacovitrectomy. METHOD: Retrospective, descriptive and comparative study of patients with a diagnosis of proliferative diabetic retinopathy with phacovitrectomy or vitrectomy procedure. Personal background data, type of surgical intervention and grade of the surgeon who carried out the procedure were obtained. RESULTS: 1227 files of diabetic patients with vitrectomy or phacovitrectomy were reviewed. 65% presented systemic arterial hypertension. The average glomerular filtration rate was 63.50 (±32.36)â¯ml/min/1.73â¯m2 and glycosylated hemoglobin (HBA1C) of 8% (4.6 to 15%). In the comparison of variables, a significant difference in the rate of vitreous rebleeding was obtained comparing phacovitrectomy with vitrectomy. (pâ¯=â¯0.003), in the relationship between vitrectomy with vitreous rebleeding, an odds ratio of 1.44 was obtained. CONCLUSION: The results obtained show a lower rate of rebleeding in patients undergoing phacovitrectomy in patients with proliferative diabetic retinopathy.
