Abstract

Purpose
To compare long-term clinical outcomes of pars plana vitrectomy (PPV) combined with intraoperative 360° laserpexy and pars plana vitrectomy combined with scleral encircling for the treatment of primary rhegmatogenous retinal detachment (RRD).
Methods
This retrospective, comparative case study included 70 patients who had at least 1 year of follow-up after vitrectomy for primary uncomplicated RRD from 2015 to 2019. The patients were divided into two groups. Group I included 34 patients who underwent PPV + 360° laserpexy (LP), while group II included 36 patients who underwent PPV + scleral encircling (SE). Main outcome measures were the anatomical success rate, the functional success rate, final best-corrected visual acuity (BCVA), and the incidence of post-operative complications. We also examined the long-term changes in axial length, corneal curvature, and refractive error before and after surgery.
Results
LP and SE groups showed no significant differences with respect to the primary anatomical success rate (97.05% and 94.44%, respectively; p = 0.592) or the functional success rate (BCVA ≥ 20/40 at final follow-up; 82.35% and 77.78%, respectively; p = 0.635). Detachment reoccurred in three cases (one in the LP group and two in the SE group) because of proliferative vitreoretinopathy; both cases in the SE group had successful anatomical re-attachment after repeating the PPV procedure. Complications included post-operative epiretinal membrane and cystic macular edema, as well as increased intraocular pressure.
Conclusions
Primary vitrectomy combined with 360° laserpexy has effectiveness similar to vitrectomy combined with scleral encircling in patients with RRD in long-term clinical outcomes.
