Combined surgery may reduce hypotony risk in patients with diabetic retinopathy
Vitrectomy combined with cataract surgery may decrease the risk of early postoperative hypotony in patients with diabetic retinopathy, according to a study.
Three hundred two eyes that underwent sutureless vitrectomy for diabetic retinopathy were retrospectively reviewed; 207 eyes underwent combined vitrectomy and cataract surgery, and 95 eyes underwent vitrectomy only.
Abnormal high and low IOP changes were monitored postoperatively in all patients at days 1, 7, 14 and once a month thereafter.
Four eyes in the combination surgery group had postoperative hypotony compared with seven eyes in the vitrectomy only group (P = .048). Multivariate analysis also showed a higher association of postoperative hypotony without cataract surgery (P = .045).
“This combined surgery may have not only the known advantages of conventional combined surgery but also those such as less conjunctival fibrosis and maintenance of a stable IOP in the early postoperative period,” the study authors said.
