Two DRCR.net studies investigating pneumatic vitreolysis in vitreomacular traction and macular hole showed relatively good efficacy but were terminated before completion due to safety concerns.
“Pneumatic vitreolysis (PVL) is an in-office procedure for vitreomacular traction (VMT) and macular hole involving injection of an expansile gas such as C3F8,” Clement Chan, MD, said at the virtual Association for Research in Vision and Ophthalmology meeting. “If found to be safe and effective, PVL would be a less invasive, lower-cost alternative to vitrectomy.”
