BACKGROUND To investigate the efficacy and safety of continuous ab interno repairing of traumatic cyclodialysis cleft in severe ocular trauma using a 30-gauge (G) needle. METHODS Fifteen patients (15 eyes) with traumatic cyclodialysis cleft admitted to the ocular trauma department of our hospital from July 2014 to December 2018 were included in this study. After the bulbar conjunctiva corresponding to the ciliary body was incised along the corneal limbus, an incision was made along the corneal limbus on the opposite side. A 30G needle with a 10-0 suture entered the anterior chamber from the incision and passed through the ciliary body with clefts and the sclera to fixate the ciliary body on the sclera wall with continuous mattress suture. The best corrected visual acuity (BCVA) and intraocular pressure (IOP) were observed preoperatively and postoperatively. In vivo ultrasound biomicroscopy (UBM) was performed to observe closure of cyclodialysis cleft before and after surgery. RESULTS Fifteen patients successfully underwent continuous mattress suture for repair of cyclodialysis cleft. No bleeding and suture breakage were reported during surgery. After surgery, the UBM during follow-up showed satisfactory closure of the cyclodialysis cleft. The BCVA and IOP were improved to different degrees. The difference between the preoperative IOP and the postoperative IOP (1 week) was statistically significant (preoperative: 6.49 ± 0.98 mmHg, postoperative: 16.17 ± 4.65 mmHg, t = - 8.43, P < 0.05), and the difference between the preoperative IOP and the postoperative IOP (1 month) was also statistically significant (preoperative: 6.49 ± 0.98 mmHg, postoperative: 14.63 ± 3.63 mmHg, t = - 8.38, P < 0.05). Duration of outpatient follow-up was 3 to 12 months. No complications, including exposed knots, loose sutures, decompensation of corneal endothelium, sympathetic ophthalmia, endophthalmitis and choroidal detachment, were reported. CONCLUSION Continuous ab interno repairing of traumatic cyclodialysis cleft in severe ocular trauma using a 30G needle is a safe and effective procedure with simple operation, little tissue damage and few complications.

在严重眼外伤中使用30号针头连续进行腹腔内外伤性修复性环透析修复的临床观察。

背景技术为了研究使用30号（G）针在严重眼部外伤中连续进行腹部内翻修复外伤性环透析裂隙的疗效和安全性。方法纳入2014年7月至2018年12月我院眼外伤科收治的15例（15眼）创伤性血液透析裂隙患者。在沿角膜缘切开与睫状体相对应的结膜结膜后，沿对侧的角膜缘切开一个切口。用10-0缝线缝合的30G针从切口进入前房，并穿过具有裂口和巩膜的睫状体，通过连续的床垫缝线将睫状体固定在巩膜壁上。术前和术后观察到最佳矫正视力（BCVA）和眼内压（IOP）。进行体内超声生物显微镜检查（UBM）以观察术前和术后环透析裂隙的闭合。结果15例患者成功接受了连续褥式缝合以修复环透析裂隙。手术期间无出血和缝线断裂的报道。手术后，UBM在随访过程中显示出令人满意的闭合性血液透析裂隙。BCVA和IOP均有不同程度的提高。术前眼压与术后眼压（1周）之间的差异具有统计学意义（术前：6.49±0.98 mmHg，术后：16.17±4.65 mmHg，t =-8.43，P <0.05），术前眼压和术后眼压（1个月）之间的差异也具有统计学意义（术前：6.49±0.98 mmHg，术后：14.63±3.63 mmHg，t =-8.38，P <0.05）。门诊随访时间为3到12个月。没有发现并发症，包括裸露的结，松散的缝合线，角膜内皮失代偿，交感性眼炎，眼内炎和脉络膜脱离。结论使用30G针在严重眼外伤中连续进行腹部腹腔内修复是一种安全有效的方法，操作简单，组织损伤小，并发症少。据报道包括结露，缝线松动，角膜内皮失代偿，交感性眼炎，眼内炎和脉络膜脱离。结论使用30G针在严重眼外伤中连续进行腹部腹腔内修复是一种安全有效的方法，操作简单，组织损伤小，并发症少。据报道包括结露，缝线松动，角膜内皮失代偿，交感性眼炎，眼内炎和脉络膜脱离。结论使用30G针在严重眼外伤中连续进行腹部腹腔内修复是一种安全有效的方法，操作简单，组织损伤小，并发症少。
