视神经萎缩眼视力的预测和客观判定,在眼科临床上具有重要意义,并对法医学鉴别诈盲等有较大帮助。本文选取1990年2月～1991年2月于中国医科大学一院眼科门诊确诊为偏心固视的视神经萎缩患者50眼,调查和测定其年龄、患病时间、偏心度、固视动摇范围和视力。从中随机取30眼进行因子普查和建立回归模型。具体方法为:采用电子计算机找出因子的最优非线性表达式,再用这些非线性表达式进行逐步
Vision prediction and objective judgment of optic atrophy are important in clinical ophthalmology, and it is helpful for forensic medicine to identify fraud and blindness. This study selected 50 patients with optic nerve atrophy diagnosed as eccentric fixation at the Department of Ophthalmology, First Affiliated Hospital of China Medical University from February 1990 to February 1991 to investigate and determine their age, time of illness, eccentricity, fixation range, and visual acuity. . Thirty eyes were randomly selected for factor screening and a regression model was established. The specific method is: using computer to find the optimal nonlinear expression of factors, and then use these nonlinear expressions to gradually
