Abstract

Introduction Radical anterior vitreous base dissection and lensectomy in combination with inferior 180° retinectomy will improve the anatomic success of complex proliferative diabetic vitreoretinopathies (PVR)-related retinal detachment. Our study aims to describe the anatomical and functional results of pars plana vitrectomy with retinotomies and relaxing retinectomies in patients with tractional retinal detachment in advanced PVR. Patients and methods A case series study was conducted on 28 eyes of patients with tractional retinal detachment with severe PVR. Preoperative and postoperative complications and final visual outcomes were recorded. The follow-up period was 12 months. Results Full reattachment rate was reached intraoperatively in 26 (92.9%) eyes, with final complete reattachment success rate in 22 (78.5%) eyes at least 6 months of follow-up. A total of 17 (60.7%) eyes had their best-corrected visual acuity (BCVA) improved at 6 months postoperatively, and reaching a final BCVA of more than or equal to 2/60 at 6 months. The BCVA remained stable in six (21.4%) eyes and declined in five (17.9%) eyes. The complications postoperatively included secondary glaucoma (three eyes), retinal redetachment (four eyes), and hypotony (two eyes). Conclusion Pars plana vitrectomy with relaxing retinotomies and retinectomies is an effective treatment method for complex PVR-related retinal detachment. Improved preoperative visual acuity, lower PVR extension, and silicone oil tamponade use during the early recovery period are essential factors for good anatomical and visual outcomes and a lower rate of complications.
