目的 探讨先天性较大范围永存瞳孔膜的手术治疗。方法 在显微镜下,作角膜缘3mm切口,用囊膜剪沿瞳孔残膜始部剪断,用囊膜镊夹住取出,晶状体前囊的瞳孔残膜用注吸针头吸出,切口不缝合。结果 手术5例9眼,瞳孔残膜全部取出。无晶状体混浊、前房出血等并发症发生,视力有不同程度增进,效果满意。结论 较大范围的先天性瞳孔残膜可应用显微手术治疗。
Objective To investigate the surgical treatment of congenital pupillary membrane in a large area. Methods Under the microscope, a 3 mm incision was made on the corneal limbus. The incision was excised along the initial part of the pupil with a capsule cut, and the capsule was removed with a capsule tweezer. The pupil of the anterior lens capsule was aspirated with a suction needle and the incision was not sutured. Results 5 cases of surgery in 9 eyes, all pupil residual membrane removed. Aphakia opacity, anterior chamber hemorrhage and other complications occurred, visual acuity improved in varying degrees, the effect is satisfactory. Conclusion A large range of congenital pupil remnants can be treated with microsurgery.
