曲安奈德辅助玻璃体后皮质可视化在玻璃体切割术中的应用

Application of triamcinolone acetonide assisted visualization of posterior cortex of vitreous body in vitrectomy

目的探讨曲安奈德(triamcinolone acetonide,TA)注射液在玻璃体手术中辅助剥除玻璃体皮质的作用。方法对108例(126眼)患者行玻璃体切割术,术中切除中央部玻璃体后,向玻璃体内注入0.5mL TA混悬液,对后极部视网膜表面可能残存的玻璃体进行标识,将黏附TA颗粒的视网膜皮质切除。结果 TA辅助玻璃体切割术中残余玻璃体清晰可见,TA乳白色颗粒黏附于视网膜表面的残留玻璃体皮质的部位及范围,更易于辨认及剥除。治疗后平均视力0.2931±0.1231,高于术前0.1423±0.0485。结论 TA在玻璃体切割术中的应用有助于辨别残留的玻璃体皮质,提高了手术的安全性,缩短了手术时间。

Objective To investigate the effect of triamcinolone acetonide（TA） injection on assisting to remove cortex of vitreous body during vitrectomy. Methods About 108 patients（126 eyes） were taken vitrectomy.After removing vitreous body at the central part,0.5 mL TA suspension was injected into vitreous space.The remaining vitreous body at rear retinal surface was marked.The retinal cortex with TA particles was removed. Results The section and scope of remaining cortex of vitreous body at retinal surface were clearly visible and recognized in vitrectomy with auxiliary TA injection,so it was easy to be removed.The mean visual acuity was 0.293 1±0.123 1 before treatment,which was higher than 0.142 3±0.048 5 before treatment. Conclusion The application of TA injection in vitrectomy helps to identify residues,improves safety of operation,and shortens operating time.
