白内障患者的眼轴及角膜曲率测量值统计分析

目的:通过国人白内障患者的眼轴及角膜曲率测量反映一寂静人群的眼解剖参数的正常值。方法:对1010例(1575眼)白内障患者术前的生物测定值进行统计分析。其中年龄相关性白内障891例(1437眼),外伤性白内障30例(38眼),先天性白内障53例(100眼)。结果:男性60岁以上组眼轴平均值为(24.15±1.51)mm,50~60岁组眼轴平均值为(25.08±3.10)mm;女性60岁以上组眼轴平均值为(23.56±1.73)mm,50~60岁组眼轴平均值为(24.50±2.85)mm;男性患者50岁以上角膜曲率平均值为(43.70±1.76)D,女性60岁以上组角膜曲率平均值为(44.62±1.54)D。17~30岁的外伤性白内障患者的眼轴平均值(24.07±1.75)mm,与正常眼轴(24mm)的差异无显著性(t=0.250,P=0.804)。先天性白内障患者的眼轴最大值为27.15mm,最小值为19.2mm,双眼相差最大值为3mm。结论:年龄相关性白内障患者的生物测量值在一定程度上可以反映一定人群的正常值。外伤性白内障患者的眼轴与正常眼轴的差异无显著性。先天性白内障患者的眼轴变异程度大。

Statistical analysis on axis oculi and keratometry of cataract patients

AIM: To evaluate the normal anatomical parameters of a silent crowd through measuring axis oculi and keratometry of Chinese cataract patients. ·METHODS: Anatomical parameters of 1 010 cataract patients (1 575 eyes) were analyzed statistically, in which 927 cases (1 437 eyes) were age-related cataract, 30 cases (38 eyes) were traumatic cataract and 53 cases (100 eyes) were congenital cataract. ·RESULTS: The axis oculi mean value of male >60 years and 50-60 years old were 24.15±1.51mm and 25.08±3.10mm. In contrast, that of female >60 years and 50-60 years old were 23.56±1.73mm and 24.50±2.85mm. The keratometry mean value of male (>50 years) was 43.70±1.76D, and that of female (>60 years) was 44.62±1.54D. The axis oculi mean value of traumatic cataract patients (17-30 years) was 24.07±1.75mm, which showed no significant difference with normal axis oculi (t=0.250,P=0.804). The axis oculi maximum and minimum value of congenital patients were 27.15mm and 19.2mm, res-pectively.·CONCLUSION: The anatomical parameters of age-related cataract patients can reflex the normal value in some degree, and there is no significant difference between the axis oculi of traumatic cataract patients and the normal. The axis oculi of the congenital cataract patients may vary a great deal.
