目的:观察50～79岁汉族和维吾尔族患者中央区角膜内皮细胞密度。方法:选择50～79岁年龄段维吾尔族患者180例,50～59岁年龄段60例,60～69岁年龄段60例,70～79岁年龄段60例;及汉族患者180例,50～59岁年龄段60例,60～69岁年龄段60例,70～79岁年龄段60例,均取右眼,应用非接触型角膜内皮显微镜观察角膜内皮细胞密度。结果:50～59岁年龄段维吾尔族角膜内皮细胞密度为2 608.4±327.6个/mm2,汉族角膜内皮细胞密度为2 728.6±284.6个/mm2,两者对比P<0.05;60～69岁年龄段维吾尔族角膜内皮细胞密度为2 547.0±292.5个/mm2,汉族角膜内皮细胞密度为2 672.9±312.5个/mm2;70～79岁年龄段维吾尔族角膜内皮细胞密度为2 452.8±434.5个/mm2,汉族角膜内皮细胞密度为2 660.2±374.9个/mm2,两者对比P<0.05。50～79岁年龄段维吾尔族角膜内皮细胞密度为2 536.1±360.4/mm2,汉族角膜内皮细胞密度为2 688.6±324.9个/mm2,两者对比P<0.05;结论:在50～59岁,60～69岁,70～79岁各年龄段,及50～79岁年龄段比较,汉族患者角膜内皮细胞密度较维吾尔族角膜内皮细胞密度高。
Objective: To observe the central corneal endothelial cell density in Han and Uygur nationality from 50 to 79 years old. Methods: A total of 180 Uighur patients aged 50-79 years, 60 patients aged 50-59 years, 60 patients aged 60-69 years, 60 patients aged 70-79 years and 180 patients with Han- 60 cases of 59-year-old age range, 60-year-old age range of 60 cases, 70 to 79-year-old age group of 60 cases, both right eye, the use of non-contact corneal endothelial microscopy corneal endothelial cell density. Results: The density of corneal endothelial cells in Uyghur ethnic groups was 2 608.4 ± 327.6 / mm2 from 50 to 59 years old, and the density of corneal endothelial cells in Han was 2 728.6 ± 284.6 / mm2, P <0.05. The age range 60-69 The density of corneal endothelial cells in Uighur was 2 547.0 ± 292.5 / mm2, the density of corneal endothelial cells in Han was 2 672.9 ± 312.5 / mm2; the density of Uygur corneal endothelial cells in 70-79 years old was 2 452.8 ± 434.5 / mm2, The density of corneal endothelial cells in Han population was 2 660.2 ± 374.9 / mm2, P <0.05. The density of Uygur corneal endothelial cells was 2536.1 ± 360.4 / mm2 from 50 to 79 years old, and the density of corneal endothelial cells was 2 688.6 ± 324.9 / mm2, P <0.05; P <0.05) .Conclusion: The corneal endothelial cell density of Han nationality patients is higher than that of Uyghur in 50 ~ 59 years old, 60 ~ 69 years old, 70 ~ 79 years old age group and 50 ~ 79 years old age group High density of corneal endothelial cells.
