Case series shows pars plana vitrectomy restores optical clarity in ocular trauma, suggesting that minimally invasive vitrectomy effectively clears hemorrhage and debris.
Fifteen patients underwent a pars plana approach vitrectomy and membranectomy after acute and chronic injury. In all cases the lens fragments, hemorrhage, and secondary membranes were removed restoring clarity to the ocular media. In two cases the final visual acuity was limited by preexisting retinal injury. The advantages of pars plana approach are the small incision and minimal ocular manipulation during surgery. In the presence of retinal injury, diathermy during the procedure or photocoagulation within 24 hours is also indicated.
