摘 要: | 目的;探讨放射状角膜切开(RK)术后角膜内皮细胞(CEC)形态计量学变化及其临床意义。方法:对16例患者(28眼)在RK术前、术后2周至2年期间进行了活体CEC显微镜观察和计算机图像分析。结果:与术前相比,术后早期细胞面积变异系数、长径、周长明显扩大,形状系数减小(P〈0.01),术后6个月,上述各形态计量学指标基本恢复正常(P〉0.05);在术后1年内细胞密度虽有下降,但无统计学意义。结论:RK

A quantitative analysis of the morphology of corneal endothelial cells following radial keratotomy |

Abstract: | Objective: To study the morphometric changes of the corneal endothelial cells (CEC) following radial keratotomy (RK) and to evaluate their clinical significance. Methods: The CEC of 16 patients (28 eyes) were examined by specular microscopy and the morphology of the CEC were analysed by computer assisted image analysis system before RK and 2 weeks to 1 year after the operation. Results: As compared with preoperation, at the early stage postoperatively the CEC showed an obviously higher coefficient of variation in cell size, long axis and perimeter, and a lower figure coefficient (P<0.01). At 6 months postoperatively, the morphometrical characteristics returned to normal ( |
