• A new single-masked randomized controlled trial aims to assess the effectiveness of combining vitrectomy with intravitreal dexamethasone implant in treating proliferative diabetic retinopathy, involving 100 participants over 24 weeks.
• The study will evaluate whether the combination therapy improves visual outcomes and reduces postoperative complications like macular edema compared to vitrectomy alone in PDR patients requiring surgery.
• The trial, registered as ChiCTR2200059760, will measure key outcomes including corrected visual acuity, retinal reattachment rates, and central macular thickness to determine the safety and efficacy of this novel approach.
