Intravitreal bevacizumab preceding vitrectomy may enable good outcomes for diabetic retinopathy, potentially aiding surgical maneuvers and reducing complications, a study found.
A comprehensive literature search identified six randomized, controlled trials and one comparative study that were used to compare vitrectomy alone in 142 eyes and vitrectomy with Avastin (bevacizumab, Genentech) pretreatment in 139 eyes.
Occurrence of intraoperative bleeding and frequency of endodiathermy were significantly lower in the bevacizumab pretreatment group (P < .01). Moreover, this group required less surgical time (P = .003), and postoperative outcomes showed that blood reabsorption also took less time (P = .04), incidence of recurrent vitreous hemorrhage was insignificantly less and final best corrected visual acuity was better (P = .003).
Limitations to this analysis included potential publication bias, a large disparity in the quality of included studies and the fact that studies were heterogeneous in terms of location, population, number of patients and basal condition.
