Methotrexate Infusion and Intrasilicone Injection During Diabetic Vitrectomy

Summary

The goal of this interventional clinical trial is to assess anatomical and functional outcomes of methotrexate use in irrigating fluid during parsplana vitrectomy combined with intrasilicone injection at end of surgery in patients with advanced proliferative diabetic retinopathy. The main questions it aims to answer are: 1. Does methotrexate use in irrigating fluid during parsplana vitrectomy combined with intrasilicone injection at end of surgery decrease the post operative vitreoretinal proliferation after vitrectomy in patients with advanced proliferative diabetic retinopathy? 2. Does methotrexate use in irrigating fluid during parsplana vitrectomy combined with intrasilicone injection at end of surgery improve post operative functional outcome after vitrectomy in patients with advanced proliferative diabetic retinopathy? Researchers will compare the anatomical and functional outcomes after vitrectomy in patients with advanced proliferative diabetic retinopathy without using methotrexate.
