Objective To observe the effect of internal limiting membrane peeling combined with intraocular injec-tion of triamcinolone(TA)in the treatment of PDR silicone oil eye with macular edema.Methods Patients were treated in our hospital for minimally invasive vitrectomy due to PDR,for postoperative macular edema,oil extraction should be combined with internal limiting membrane peeling and intrabulbar injection of TA.BCVA and macular edema were ob-served before and after surgery.Results BCVA improved and macular edema reduced after the operation,with the differ-ence being statistically significant.Conclusion The patients with PDR silicone oil eyes complicated with macular edema,surgical treatment using oil extraction combined with inner boundary membrane peeling and intraocular injection of TA can effectively reduce macular edema,improve the best corrected visual acuity.
