High Pressure 23G Vitrectomy to Treat Proliferative Vitreoretinopathy

Objective: To present the 23 gauge3 high pressure vitrectomy (80mmHg), to treat retinal detachment with Proliferative Vitreoretinopathy (PVR) 2. 

Material and methods: 32 patients with retinal detachment and proliferative vitreoretinopathy, treated with 23G vitrectomy, using the Dorc vitrectomy system, using high pressure air infusion (80mmHg) and release of the traction points caused by the PVR through tractional cuts or retinostomy. 

Results: In all cases we obtained the application of the retina at the end of the surgery. In 4 cases there was redetachment of the retina, and they underwent surgery again, using the same surgical technique successfully in 3 patients. There was significant improvement in visual acuity in the post-surgery compared to the pre-surgery.

Conclusion: High pressure 23G vitrectomy (80mmHg) is a good alternative for the treatment of retinal detachment with Proliferative Vitreoretinopathy (PVR) 2, with the advantage of not needing the use of liquid perfluorocarbon or another.
