Absence of an encircling scleral buckle associated with retinal redetachment in giant retinal tear cases
Performing pars plana vitrectomy combined with an encircling scleral buckle appears to be more effective for preventing retinal redetachment in patients treated for complex retinal detachments associated with giant retinal tears, according to a study by researchers in The Netherlands.
Fleur Goezinne, MD, and colleagues at University Hospital Maastricht investigated the long-term outcomes and possible risk factors for retinal redetachment among 30 eyes treated with pars plana vitrectomy for retinal detachments due to giant retinal tears. They published their results in the April issue of Retina.
After undergoing only one vitrectomy procedure, nine of the 30 eyes (30%) experienced a redetachment. However, 29 eyes (96.7%) ultimately achieved attached retinas, according to the study.
"After multivariate analysis, the absence of an encircling scleral buckle (P = .008) was significantly associated with redetachment," the authors said.
