曲安奈德在玻璃体视网膜手术中的应用

目的观察曲安奈德（TA）注射液在玻璃体视网膜手术中协助辨别和清除残留玻璃体皮质的作用及效果。方法2003年8月至2005年 2月，对在玻璃体视网膜手术术前和手术中未发现明确玻璃体后脱离的1 046例1 056只眼，经大部分玻璃体切除后，玻璃体内注射TA混悬液约1~2 mg，对后极部视网膜表面可能残存的玻璃体皮质进行标识，将粘附TA的玻璃体皮质完全剥除。结果乳白色的TA粘附在玻璃体皮质上可清楚地显示附着于视网膜表面的残留玻璃体皮质的部位及范围，使之容易辨认并易于剥除。结论TA在玻璃体视网膜手术中的应用有助于辨别残留的玻璃体皮质，提高彻底清除玻璃体皮质的手术效率及成功率。(中华眼底病杂志,2005,21:226-228)

The application of the triamcinolone acetonide injection in vitreoretinal surgery

Objective To discuss the role and effect of the triamcinolone acetonide (TA) injection applied in the vitreoretinal surgery for assisting to distinguish and removal residual cortex. Methods One thousand and forty-six patients ((1 056) eyes) underwent a PPV at West China Eye Center from August 2003 to February 2005. These affected eyes were selected without posterior vitreous detachment pre- and intra-operatively, and underwent intravitreal injection with TA 1-2 mg to label the residual vitreous cortex on the surface of the posterior retina after removal of the majority vitreous. Results The location and coverage of the residual vitreous cortex were clearly be shown by the white appearance of TA labeled residual vitreous, and the residual vitreous cortex was conveniently to be recognized and removed. Conclusion The application of intravitreal injection with TA is helpful for identification and elimination of the residual vitreous cortex in vitreoretinal surgery.
