探讨23G玻璃体切割系统在高海拔地区玻璃体切割手术中的应用。 方法:对本院需行玻璃体切割的住院患者31例32眼采用23G玻璃体切割术，包括玻璃体积血、黄斑裂孔、黄斑前膜、晶状体后脱位、视网膜脱离、Tersonz综合征、玻璃体积血合并视网膜脱离。 结果:手术过程顺利，无需扩大巩膜穿刺口，手术后并发症主要是低眼压。 结论:23G经结膜无缝合玻璃体切割系统,与25G玻璃体切割比较效率更高，可以同20G一样处理周边部玻璃体视网膜，同时具有25G免缝合、愈合快、手术时间短、术后并发症少的优点，因此可在高海拔地区玻璃体切割手术中广泛应用。

To investigate the application of 23-Gauge (23G) vitrectomy system in high altitude area. METHODS:In the applying of 23G vitrectomy system, the vitrectomy had been done for 32 cases (32 eyes), including vitreous hemorrhage, macular hole, macular pucker, posterior dislocation of lens, retinal detachment, Tersonz syndrome, vitreous hemorrhage combining with retinal detachment. RESULTS:The operations were successful, without expanding sclera puncture.The postoperative syndrome mainly was low IOP. CONCLUSION:In 2000, the clinical using of 23G vitrectomy system without conjunctival suture was first reported. It is more efficient than 25G vitrectomy system, which can process the retina around like 20G and has the advantage of healing fast ，seamless， short operation time and less postoperative syndrome as 25G vitrectomy system. So it can be widely applied in the vitrectomy in high altitude area.
