穿透性角膜移植治疗角膜白斑78例

目的探讨穿透性角膜移植(PK)术治疗角膜白斑的疗效、并发症及处理方法。方法对78例(78眼)角膜白斑患者行穿透性角膜移植术,并观察3～16月,对并发症即时给予药物及手术治疗。结果术后视力较术前明显提高,差异有显著性,P<0.01。随访3～16月植片透明69眼(88%),半透明9眼(12%),排斥反应13眼(17%),继发青光眼7眼(9%)。结论PK术是治疗角膜白斑提高视力的最佳方法,手术成功率取决于植床条件、植片质量、手术技巧及并发症处理。

Treatment of 78 cases of leucoma with penetrating keratoplasty

Aim To study penetrating keratoplasty (PK) in treatment of leucoma in terms of its therapeutic effects, complications as well as management of the co mplications. Methods A total of 78 cases (78 eyes) of leucoma were treated with PK and followed up for 3 to 16 months. Complications were managed with medicin es or operations. Results Visual acuity after the treatment was significantly b etter than that before (P <0.01). During the follow-up, the graft remained trans parent in 69 eyes (88%), semi-transparent in 9 eyes (12%) and was rejected in 13 eyes (16.67%); secondary glaucoma developed in 7 eyes (9%). Conclusion PK is t he optimal treatment for leucoma. Its success depends on the condition of the gr afting bed, the graft quality, the operational skills and management of complica tions.
