胎儿脐带插入巩膜加固术长期疗效观察

The long-term results of scleral reinforcement by means of umbilical cord grafting

目的 研究胎儿脐带插入巩膜加固术治疗进行性近视的长期疗效。方法 手术 12 3例 ,其中 5 5例 10 7眼随访至术后 5年半作为手术组 ,随机抽取进行性近视 16例 3 2眼作为对照组 ,观察两组近视发展情况。结果 5年半后手术组矫正视力、屈光度、眼轴长度以及角膜屈折力与术前相比无差异 ;术后 5年半预期屈光度明显高于实际值 ;除了早期筋膜炎以外未发现其它并发症。结论 胎儿脐带插入巩膜加固术治疗进行性近视安全有效 ,可以阻止近视的发展。

ObjectiveTo study the long term results of scleral reinforcement by means of umbilical cord grafting to treat progressive myopia.Methods123?cases were made scleral reinforcement,55 cases(107 eyes,operating group)and 16 cases(32 eyes,control group,were randomly chosen)were followed up up to 5 6?a after operation.The diopters of operating group 5 6 a later were predicted according to the speed of myopic progress during 2～5 a before operation.ResultsThe corrected visual acuity,myopic diopter,eye axes and keratometry in the preoperative group and 5 6 a postoperative group were 4 761±0 294 and 4 794±0 288(0 20<P<0 50),(-13 093±5 021)D and(-13 395±5 445)D(P>0 50),(28 435±2 432)mm and (28 286±2 483)mm(P>0 50),(42 984±1 82)D and (42 654±1 537)D(0 20<P<0 50),respectively.The predicted diopter,(-21 865±8 214)?D was significantly higher than the actual diopter 5 6 a after operation in the operating group.The early ocular fasciitis was the only complication and disappeared in l week.ConclusionThe scleral reinforcement by means of umbilical cord grafting is safe and effective on progressive myopia.It can prevent its development.
