方法：将用酒精脱水固定处理后的胎儿脐带复水后，采用单条带后巩膜加固法，对100例136眼病理性近视患者，行手术治疗，观察其术后视力、屈光度、眼轴及并发症，随访1.5a。

结果：术后近视度数稳定或减少者占91.2%； 矫正视力术后0.5，1，1.5a时稳定及提高的分别为125眼(91.9%)，127眼(93.4%)和124眼(91.2%)； 患者术前眼轴为29.81±1.87mm，术后0.5，1，1.5a眼轴分别为29.82±1.90，29.83±1.79，29.79±2.06mm，与术前比较，差异均无显著性(P>0.05)； 3例术后出现短暂复视，无视网膜脱离、玻璃体出血、排斥反应等严重并发症发生。

结论：使用胎儿脐带行后巩膜加固术是一种安全有效的治疗方法，可以阻止近视发展，其远期疗效有待进一步观察。

METHODS: Totally 100 cases(136 eyes)with pathologic myopia were performed surgery after the posterior scleral reinforcement method with single band of rewatered fetal umbilical cord which had dehydration of alcohol fixation treatment. Postoperative visual acuity, diopter, eye axis and complications were observed. And the follow-up time lasted for 1.5 years.

RESULTS: After surgery, visual acuity of myopia stable or decreased accounted for 91.2%; corrected visual acuity was stable or improved after 0.5,1,1.5 years, third year respectively in 125 eyes(91.9%), 127 eyes(93.4%)and 124 eyes(91.2%); preoperative axial length of patients was 29.81±1.87mm while postoperative axial length after the 0.5,1,1.5 years respectively were 29.82±1.90mm, 29.83±1.79mm, 29.79±2.06mm. Compared with the preoperative axial length, there was no significant difference(P>0.05). 3 cases had postoperative transient diplopia. No retinal detachment, vitrectomy hemorrhage, rejection and other serious complications occurred.

CONCLUSION: Posterior scleral reinforcement surgery with fetal umbilical cord is a safe and effective treatment method which can prevent the development of myopia while the long-term effects need further observation.
