Transconjunctival 23-gauge vitrectomy for rhegmatogenous retinal detachment

Objective To observe clinical efficacy of 23-gauge (23G) transconjunctival vitrectomy for rhegmatogenous retinal detachment.Methods 23 eyes of 23 patients with rhegmatogenous retinal detachment had undergone 23G transconjunctival vitrectomy with perfluoropropane gas (C3F8) or silicone oil tamponade.Scleral bulking was done for inferior retinal hole.And phacoemulsification was done for patients with cataract at the same time.The follow-up ranged from 3 to 10 months.The postoperative retinal reposition and visual acuity were observed.Results The surgery was sucessfully completed in 23 eyes.The retinal reattached in 21 eyes (91.30％) 3 months after surgery,The 2 eyes (8.70％) recurrred retinal detachment were accepted silicone oil tamponade for retinal reattachment.The other complications were not found.3 months postoperative vision:(1) In the eyes without macular detachment:the preoperative best corrected visual acuity (BCVA) was 0.1 ～ 0.5,LogMAR visual acuity 1.0 ～ 0.3,the average 0.42 ± 0.29,postoperative BCVA was 0.2 ～ 0.5,LogMAR visual acuity 0.7 ～ 0.3,the average 0.38 ± 0.19,(t =1.83,P ＞0.05),there was no statistically significant difference compared with the preoperative one.(2) In the eyes with macular detachment:The preoperative BCVA was 0.08 ～ 0.2,LogMAR visual acuity 1.1 ～ 0.7,the average 0.81 ± 0.13,the postoperative BCVA was 0.15 ～ 0.5,LogMAR visual acuity 0.8 ～ 0.3,the average 0.47 ± 0.26,the difference was statistically significant compared with the preoperative one (t =5.78,P＜ 0.05).Conclusion 23G transconjunctival vitrectomy is an effective surgery for the management of retinal detachment.
