摘要
目的:研究高度近视眼的对比敏感度(CS)改变。方法:高度近视组为30例患者60眼,年龄12~62(平均36)岁,屈光度为-6.00^-21.00 D,平均-13.50 D,最佳矫正视力≥0.8。与高度近视组年龄匹配的对照组30例60眼为视力正常患者,对照组裸眼视力≥1.0。高度近视组及对照组均无任何影响CS的眼疾,亦无其他可能会影响CS的全身性疾病。所有患者CS均由同一医师用CSV-1000E对比敏感度测试仪进行测试。结果:高度近视眼的CS在各空间频率区均有不同程度的降低(P<0.05)。结论:CS的检查可作为评价高度近视眼视功能的一种手段和指标。
Objective.To study analyze sthe contrast sensitivity of high myopia. Methods ： The contrast sensitivity function （CSF） in 60 eyes of 30 patients with high myopia was studied with normal subjects as control. Those with other ocular disease or systemic disease were excluded to avoid any possible affection. The patients were aged from 12 to 62 years. Corrected vision were all over O. 8 in high myopia, and the control was more than 1.0 . The contrast sensitivity function was measured with CSV - 1000E Vision Testing Instrument （provided by VECTOR VISION company）. Results：The results revealed that the CSF of high myopia in each space-frequency range was decreased. The difference between high myopia group and control group was significant （P 〈 0.05 ）. Conclusion ： The CSF can be used as a criterion for the evaluation of high myopia.
