© 2017 Acta Ophthalmologica Scandinavica Foundation. Symptomatic vitreomacular adhesion (sVMA) is defined as visual loss secondary to foveal damage from vitreomacular traction (VMT) and includes isolated VMT, impending macular hole (MH), and full-thickness MH with persisting vitreous attachment. Management options include pars plana vitrectomy (PPV), intravitreal ocriplasmin, intravitreal gas injection or observation. This synthesis of the literature aimed to assess the safety and efficacy of intravitreal gas for sVMA. Articles describing patients with VMT or MH treated with intravitreal expansile gas were selected by systematic literature review using MEDLINE, EMBASE, and the Cochrane Database of Controlled Trials (CENTRAL) up to September 2016. The main outcomes at 1 month and final review were logarithm of the minimum angle of resolution (logMAR) visual acuity (VA), anatomical success (absence of both VMT and MH, without PPV) and adverse events (AEs). The intended comparator was observation. Nine of 106 identified articles were eligible, and none were randomized controlled trials. The mean VA of 91 eyes improved from 0.55 (Snellen equivalent 6/21) to 0.48 (6/18) logMAR at 1 month and to 0.35 (6/13) logMAR at final review. The mean VA at final review, prior to a vitrectomy, was 0.42 (6/16). Anatomic success was 48% at 1 month and 57% at final review. The reported AEs comprised retinal detachment in two highly myopic eyes. Intravitreal gas injection can relieve sVMA. Larger controlled studies are needed to determine safety and efficacy relative to observation, ocriplasmin, or vitrectomy.
