Abstract
In our clinic we used trypan blue staining routinely for removal of internal limiting membranes (ILM) and epiretinal membranes (ERM) during vitreoretinal surgery for PVR retinal detachment. We treated 27 eyes of 27 patients with severe PVR retinal detachment with vitreoretinal surgery. After complete vitrectomy and removal of epiretinal membranes we injected 0.15 % trypan blue solution and proceeded with further removal of the visualized remaining epiretinal membranes and ILM. We performed relaxing retinotomies in 14 eyes. Follow-up lasted six months. After the first surgery the retina was reattached in 24 of 27 eyes and after the second surgery in all eyes. The final visual acuity was: hand movements in 3 eyes, 1/50 or better in 24 eyes (eight of them had a visual acuity of 0.1 - 0.5). No case of macular pucker was observed during the follow-up. Trypan blue staining during vitreoretinal surgery in PVR retinal detachment therapy allows complete removal of ILM, ERM, and peripheral vitreous. It upgrades the quality of the surgery.
