Background/objectives: To compare the efficacy of intraoperative localized and 360° laser retinopexy in cases of rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy and air tamponade.
Subjects/methods: In this interventional, prospective, randomized, comparative study, 93 consecutive cases of RRD were enroled. After randomization 48 eyes received circumferential, while 45 underwent localized intraoperative laser retinopexy. Number and position of the retinal breaks, presence of proliferative vitreoretinopathy and/or lattice degeneration were recorded. Anatomical and visual outcome of the two groups were compared at 6 months postoperatively.
Results: Baseline characteristics did not significantly differ between groups. The single-operation reattachment rate was 86.66% in localized group and 89.58% in 360° group. The difference was not significant. (P = 0.46, χ2 test). At 6 months postoperatively, visual acuity (logMAR) was 0.06 ± 0.05 in localized group and 0.05 ± 0.03 in 360° group. The difference was not statistically significant (P = 0.673, t-test).
Conclusions: Localized laser resulted to be as effective as 360° laser application; this may lead some advantages in term of lower invasiveness, reduction risk of complications and time saving.
