目的 观察改良后巩膜加固术对变性近视的治疗效果。方法 对有完整资料的 2 5例 (4 2眼 )患者手术前后视力、屈光度、眼轴长度、并发症及眼底情况进行了对比观察。结果 术前矫正视力 0 0 6～ 1 0 ,术后全部患者视力均有不同程度提高 ,矫正视力为 0 0 8～ 1 2 ;术前眼轴长度 2 9 45± 1 73mm ,术后均有不同程度减少 ,术后眼轴 2 8 15± 1 85mm ,两者相比有显著性差异(P <0 0 1)。随访 3年 ,眼轴长度为 2 8 2 3± 1 98mm与术后相比无显著性差异 (P >0 0 5 )。术前屈光度 16 67± 4 3 3D) ,术后屈光度 14 3 6± 4 43D。结论 改良后巩膜加固术能阻止近视的发展 ,保护视功能 ,是目前治疗变性近视的有效方法
Objective To observe the therapeutic effect of modified scleral reinforcement on degenerative myopia. Methods Visual acuity, refraction, length of axial length, complications and fundus of 25 patients (42 eyes) with complete data were compared before and after operation. Results The preoperative corrected visual acuity was 0 0 6 ~ 1 0. The visual acuity of all the patients were improved to some extent after operation. The corrected visual acuity was 0 0 8 ~ 1 2. The axial length before operation was 29 45 ± 1 73 mm Degree of reduction, postoperative axial length of 2 8 15 ± 1 85mm, there was significant difference between the two (P <0.01). After 3 years of follow-up, axial length of 2882 ± 988mm was not significantly different from that of postoperative (P> 0.05). Preoperative refraction 16 67 ± 4 3 3D), postoperative refraction 14 3 6 ± 4 43D. Conclusion Improved scleral buckling can prevent the development of myopia, protect the visual function, is currently an effective method of treatment of degenerative myopia
