方法：选取2013-01/10在我院采用23G 玻璃体切割系统治疗特发性黄斑裂孔患者28例28眼，进行回顾性研究。对患者进行 3～12mo的术后随访观察，进行疗效评价与分析。

结果：23G微创玻璃体切割术治疗特发性黄斑裂孔28 眼，27眼黄斑裂孔愈合，1眼未愈合。术后1，3mo矫正视力较术前有显著提高(χ²=8.65，P=0.003； χ²=10.33，P=0.001)。光学相干断层扫描(optical coherence tomography，OCT)提示黄斑区裂孔封闭。术中切口缝合5例(18%)。术后眼压与术前相比差异无统计学意义。术后未发生眼内炎、视网膜脱离、玻璃体出血等并发症。

结论：23G微创玻璃体切割术是治疗特发性黄斑裂孔的一种安全有效的方法，对于简单的黄斑区手术考虑首选23G微创玻璃体切割术。

METHODS: In this retrospective study, 28 eyes of 28 consecutive patients who underwent 23-gauge transconjunctival sutureless vitrectomy for idiopathic macular hole between January 2013 and October 2013 in our hospital were evaluated. The follow-up time was 3-12mo. The operation effects were analyzed.

RESULTS: The macular hole was closed in 27 eyes of 28 eyes which underwent 23G transconjunctival sutureless vitrectomy and not closed in 1 eye after surgery. Best-corrected visual acuity at postoperative 1, 3mo was significantly improved compared to pre-operation(χ²=8.65, P=0.003; χ²=10.33, P=0.001). The macular hole was closed as shown by OCT. Intraoperative incision was sutured in 5 cases(18%). There was no statistically significant difference in intraocular pressure between pre-operation and post-operation. No post-operative complications such as endophthalmitis, retinal detachment, vitreous hemorrhage came up.

CONCLUSION: 23G transconjunctival sutureless vitrectomy is observed to be safe and effective technique in the treatment of macular hole. It is therefore our preferred system for straightforward macular surgery.
