研究分4步:(1)通过检测4例正常眼,确定VEP判断正常眼Snellen视力表的精确度、理想刺激参数和数据处理,获得两种视力之间的最佳联系。(2)测试34例未矫正视力的近视,确定仅由视物模糊对检测造成的影响。(3)检查18例(21眼)眼病引起视力减退者,确定VEP视力和Snellen视力之间的关系。(4)检查17例(28眼)不能解释的视力丧失患者,确定主观视力与VEP视力之间的关系。结果发现:对经临床检查证明无任何发现的视
The study was divided into four steps: (1) Through the detection of 4 cases of normal eyes, the best relationship between the two visual acuities was determined by VEP to judge the accuracy, ideal stimulation parameters and data processing of Snellen eyesight in normal eyes. (2) 34 cases of uncorrected vision test myopia, to determine only by the blurred vision on the impact of the test. (3) 18 cases (21 eyes) eye vision loss caused by examination to determine the relationship between VEP vision and Snellen vision. (4) To examine the relationship between subjective vision and VEP vision in 17 cases (28 eyes) of patients with vision loss who could not be explained. The results showed that: no clinical findings showed any findings
