The incidence of retinal redetachment after Pars plana vitrectomy with 360° endolaser.

Ghislaine Peene, Jean-Fran

Purpose: To evaluate the incidence of retinal redetachment after pars plana vitrectomy (PPV) with 360° laser for the treatment of primary Rhegmatogenous retinal detachment (PRDD). Methods: A retrospective review of 1,063 eyes after primary PPV and 360° laser retinopexy for PRRD between 2004 and 2014. Different parameters were analyzed for their influence on the redetachment rate. A multivariate regression analysis was performed. Results: The mean age was 61.49 ± 11 years. The Phakic status did not influence the success rate. The most common cause of redetachment was leakage through the original retinal tear (35.53%). Mostly, retinal breaks occurred in the superior quadrant (55.22%). The location of the break had no significant influence on the reoperation rate. Multivariate analysis identified the use of an encircling band as the only factor significantly associated with a lower reoperation rate. Conclusion: Primary vitrectomy combined with 360° laser therapy is an effective treatment in patients with PRRD. The primary anatomic success rate was 91.16%. The only factor that influenced the outcome was the positive effect of an encircling band.
