目的：观察巩膜全层切开、原位穿刺放液术在微创玻璃体切除术治疗脉络膜脱离型视网膜脱离中的安全性和临床疗效。

方法：临床病例回顾性分析。纳入2015-04/2017-04江苏省人民医院眼科住院治疗的脉络膜脱离型视网膜脱离患者20例20眼，所有患者均接受改良巩膜穿刺放液联合23G微创玻璃体切割术治疗。观察术中穿刺放液的成功率，手术前后视力、眼压变化情况，以及手术后视网膜复位率等情况。

结果：所有手术均一次顺利放出脉络膜上腔液体。患者术后视力较术前视力提高，差异有统计学意义(P<0.01)。术前眼压7.00±2.05mmHg，术后3mo时平均眼压为15.38±2.66mmHg，两者比较差异有统计学意义(P<0.01)。初次手术视网膜复位率为90%(18/20)，最终视网膜复位率为95%(19/20)。

结论：改良巩膜穿刺放液在微创玻璃体切割术治疗脉络膜脱离型孔源性视网膜脱离中可简化手术操作，降低手术难度，减少术中并发症的发生。

METHODS: From April 2015 to April 2017, 20 patients(20 eyes)with coexisting rhegmatogenous retinal detachment and choroidal detachment who were treated in Department of Ophthalmology, Jiangsu Province Hospital were enrolled in this retrospective analysis. All patients received modified scleral puncture drainage combined with 23G minimally invasive vitrectomy. This study analyzed and compared intraoperative paracentesis success rate, the incidence of intraoperative, postoperative visual acuity, intraocular pressure, and postoperative retinal reattachment rate.

RESULTS: Suprachoroidal fluid from all patients were drainaged successfully. Compared with preoperative conditions, the postoperative visual acuity was significantly improved(P<0.01). There was a significant difference in average intraocular pressure(IOP)between preoperative one and postoperative one(7.00±2.05mmHg and 15.38±2.66mmHg respectively, P<0.01). The origin retinal reattachment rate was 90%(18/20), and the final retinal reattachment rate was 95%(19/20).

CONCLUSION: The modified scleral puncture surgery in the treatment of patients with coexisting rhegmatogenous retinal detachment and choroidal detachment in 23G vitrectomy has great clinical effects. It not only simplifies the procedure of operation, but also reduces the difficulty and complication of operation.
