目的:探讨年龄对视跟踪试验的影响,旨在为临床诊断提供可靠的依据。方法:180名20-79岁正常成人,其中男88名,女92名,按年龄分成6组,每10年1个年龄组,每组30名,在两种不同的试验条件下进行视跟踪试验的测试。结果:两种试验条件下视跟踪试验的主要参数增益值及失真度,各年龄组有明显的不同(P<0.05)。随着年龄的增加,增益值逐渐减小(r=-0.37,-0.39)失真度逐渐加大(r=0.41,0.44)。结论:年龄对视跟踪试验的主要参数有影响,针对不同年龄组患者,应选择相应的诊断标准。
Objective: To explore the influence of age on visual tracking test, and to provide a reliable basis for clinical diagnosis. Methods: 180 normal adults aged 20-79 years old, including 88 males and 92 females, were divided into 6 groups according to their age. One group every 10 years, 30 in each group, were inspected under two different experimental conditions Test the test. Results: The gain and distortion of the main parameters of the visual tracking test under the two experimental conditions were significantly different among all age groups (P <0.05). As the age increases, the gain gradually decreases (r = -0.37, -0.39) and the degree of distortion gradually increases (r = 0.41,0.44). Conclusion: Age has an impact on the main parameters of visual tracking test. Corresponding diagnostic criteria should be selected for patients of different age groups.
