Compared with 20-gauge vitrectomy, performing primary 25-gauge transconjunctival sutureless vitrectomy may reduce the risk of vitreous incarceration and other sclerotomy-related complications, a study by Hong Kong researchers suggests.

Kenneth K.W. Li, MRCS, and colleagues performed pars plana vitrectomy, including 21 sclerotomies, using a 25-gauge sutureless system on seven eyes of six patients. They found that wounds had closed after an average of 1.8 months and vitreous incarceration had been relieved after an average of 2.4 months, according to the study.

"Vitreous incarceration occurred in 27.8% of procedures, and sclerotomies with vitreous incarceration took significantly longer to heal (P = .015)," the study authors said.

Infusion sclerotomies achieved wound closure significantly earlier than superonasal sclerotomies (P = .042). But no cases experienced sclerotomy-related complications, according to the study, published in the February issue of Asian Journal of Ophthalmology.
