    In this surgical video, Dr. Alexandre Assi describes the use of mitomycin C (MMC) to prevent proliferative vitreoretinopathy (PVR) in patients with chorioretinal lacerations. The application of MMC to the injury site prevents fibrocellular proliferation that typically occurs after trauma, often leading to PVR. This patient was a 13-year-old boy who sustained gunshot pellet wounds with intraorbital and intraocular foreign bodies. Dr. Assi performs a 20-gauge pars plana vitrectomy and removes the foreign bodies. He applies MMC-soaked sponges to the deep choroidal impact and exit sites, and then injects silicone oil. After 1 year, the patient’s BCVA was 20/20; he had a flat retina and inactive chorioretinal scars with no evidence of fibrosis, traction or retinal folding. The findings were published in the March 2019 issue of Eye.
