Triamcionlone acetonide(TA) and high-speed vitrectomy used for proliferative diabetic retinopathy

Objective To detect the value of using Tfiamcionlone acetonide (TA) to chromovitrectomy and high-speed vitrectomy in proliferative diabetic retinopathy (PDR).Methods After cut the axial vitreous of 31 cases (31eyes) of PDR,TA was used to dye the vitreous,and then high-speed vitrectomy technique was used to remove the residual vitreous and epiretinal membrane.During the time of fellow-up,visual acuity, intraocular pressure, whether or not had residual vitreous and the rate of retina reattaclament were recorded.Resuits The residual vitreous and epiretinal membrane can be easily identified and cut with TA and high-speed vitrectomy technique.The visual acuity of 25 cases was increased and 11 eyes (91.7%) retina reattachment after follow-up period for 3 to 10 months.Conclusions Residual vitreous and epiretinal membrane can be easily identified and cut with TA and high-speed vitrectomy technique.The procedures were performed easily,surely and safely.
