Pneumatic vitreolysis for relief of vitreomacular traction

Purpose: To evaluate the outcome of perfluoropropane (C3F8) gas injection for symptomatic vitreomacular traction (VMT) with or without Stage 2 macular hole (MH).
Methods: A retrospective review of eyes with VMT treated with 0.3 mL of C3F8 gas was performed. Patients avoided the supine position until gas resolution. Patients with small MH maintained partial face-down positioning.
Results: Forty-nine consecutive patients (50 eyes) with symptomatic VMT underwent pneumatic vitreolysis between 2010 and 2016. A posterior vitreous detachment developed in 43 eyes (86.0%) after a single gas injection, at a median of 3.0 weeks. Twenty-eight of 35 eyes (80.0%) with VMT only and all 15 eyes (100%) with a small Stage 2 MH developed a posterior vitreous detachment, with MH closure in 10 of 15 eyes (66.7%). Median baseline and last best spectacle–corrected visual acuities were 20/50 and 20/40, respectively (P
