Using 25gauge transconjunctival sutureless vitrectomy system through surface anesthesia for retinal arterial macroanuerysm with vitreous hemorrahge

Objective To discuss the effect of using TSV25G (25G transconjanctival sutureless vitrectomy system) in the treatment of retinal arterial macroanuerysm with vitreous hemorrhage.Methods The data of twelve cases (12 eyes) with vitreous hemorrhage without certain causes were analyzed retrospectively from 2011 July to 2012 July,diagnosed as retinal arterial macroanuerysm according to findings of operative fundus photography,Ophthalmology B-ultrasound,that found during operation and results of fundus photography and FFA postoperatively.All cases underwent three ports vitrectomy using 25gauge Transconjunctival Sutureless Vitrectomy System through surface anesthiasm.The operation time,postoperative BCVA,fundus photograghy and FFA were observed.Follow-up time was 1 month to 12 months.Results The operation lasted for 12-18minutes,meanly 15 minutes.Among them,the BCVA promoted in all eyes,0.1-0.3 in four eyes,0.4-0.6 in six eyes,＞0.6 in two eyes.The tumors of all eyes degenerated postoperatively,no one reoccurred in vitreous hemorrhage.Conclusions Using 25gauge transconjunctival sutureless vitrectomy system through surface anesthesia is effective and safe in treatment for for retinal arterial macroanuerysm with vitreous hemorrhage,it can promote visual acuity,shorten operation time,decrease complication.
