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.
