成人共同性外斜视术后双眼视觉的重建立及手术特点

Restoration of normal binocular vision after successful surgical correction of adult concomitant extropia

目的探讨成人共同性外斜视术后双眼视觉的重建及手术特点。方法对123例年龄≥18岁两眼视力相等或相差1～2行的共同性外斜视,术前术后检查视力、眼位、眼底,以同视机检查融合机能,以颜氏立体图检查立体视。结果术后1周113例视觉抑制或异常视网膜对应者中60例恢复正常视网膜对应,16例建立了立体视;术后6周80例视觉抑制或异常视网膜对应者中40例还恢复正常视网膜对应,并且其中14例还重建立了立体视。结论成人共同性外斜视手术不仅达到美容矫正,而且其中一部分还达到功能治愈。成人共同性外斜视在手术设计时要避免过矫。

Objective Restoration of normal binocular vision after successful surgical correction of adult concomitant extropia. Methods 123 patients of concomitant extropia with age ≥ 18 years and visual acuticy on both eyes were equal or differ blow.2 lines. Visual acuity, alignment, strabismus degree and fusion function were measured using synoptophone and stereoacuity was assessed using stereogram of Yan shaoming pre and postoperativly. Results 1 week postoperatively,60 cases restored normal retinal correspondence（NRC） in the 113 visual suppressed or abnormal retinal correspondence （ARC） patients, 16 established stereopsis in the of 60 NRC patients;6 weeks postoperativly,40 restored NRC in the 80 visual suppressed or ARC patients,14 established stereopsis in the 40 NCR patients. Conclusions Surgical correction of adult concomitant extropia could not only get hairdressing effect, part of them could get function cure.
