Giant retinal tears: clinical features and outcomes of vitreoretinal surgery at a university teaching hospital (2011–2017)

Abstract

Purpose

The purpose of this study was to report clinical features and outcomes in patients with giant retinal tears (GRTs) undergoing vitreoretinal surgery and to compare data from this contemporary series to a previous study from the same institution.

Materials and methods

A retrospective, interventional, consecutive case series was conducted for all patients diagnosed with GRTs who underwent vitreoretinal surgery between January 2011 and August 2017. Intraoperative data including the use of scleral buckling, perfluorocarbon liquid, and intraocular tamponade were collected and compared according to GRT size. These parameters, along with postoperative anatomic success and best-corrected visual acuity (BCVA), were compared with the previous series.

Results

The study included 80 eyes of 79 patients with a presentation of retinal detachment with a GRT. Management approach for repair of GRT-associated retinal detachments included scleral buckle (SB) alone (three eyes, 4%), pars plana vitrectomy (PPV) (16 eyes, 20%), and combined SB/PPV (61 eyes, 76%). Perfluorocarbon liquids were used in 60/77 eyes (78%) undergoing PPV, and silicone oil was used in 54/77 eyes (70%). Single surgery success rate was in 69/80 eyes (86%). Eyes managed with SB (including SB alone and SB/PPV) or PPV without SB had similar rates of recurrent retinal detachment (16% vs 6%; P=0.33). Anatomic success was achieved in 76/80 eyes (95%) with one or more surgical procedures, and 54/80 eyes (68%) achieved postoperative BCVA of ≥20/400.

Conclusions

In the current series, repairs of retinal detachment due to GRTs were most commonly managed with combined PPV/SB and perfluorocarbon liquid, resulting in reasonably generally favorable anatomic and visual outcomes.
