Triamcinolone Acetonide-assisted Vitrectomy:31 Cases Report

Objective: To determine the effect of triamcinolone acetonide-assisted pars plana vitrectomy.Methods: Triamcinolone acetonide(TA) solution was injected into the vitreous cavity of 31 patients(31 eyes,included 8 idiopathic macular hole patients) during pars plana vitrectomy.The vehicles were replaced by 5 ml balance salt solution(BSS) through 5 μm pore filter combined with three-way cock device.During the surgery,0.5-1.0 ml TA was used to stain the vitreous,hyaloid and internal limiting membrane.After these procedures endolaser photocoagulation,gas-fluid exchange,C_(3)F_(8) gas or silicone tamponade was performed when needed.The follow-up time was at least 4 months.Results: All 31 eyes'(100%) vitreous and hyaloid could be stained by TA clearly and be removed easily.A total of 26 patients'(26/31,83.8%) visual acuity remained stable or increased at least two lines.After surgery,two cases had high intraocular pressure and one case had cataract.No other complications were found.Conclusion: Triamcinolone acetonide could improve the visibility of the hyaloid of the vitreous and the safety of the pars plana vitrectomy.
