根据夏德昭的视力性质分析,视神经萎缩存在着中心与中心外两种固视状态,以及测量偏心固视患者视野暗点时,必须先将视线矫正到暗点计注视目标,而后按常规测量方可保证正确的测量结果等报导,用Goldmann-Weekers 暗适应计并改装了该仪器的注视灯,开展对中心与中心外固视的视神经萎缩眼暗适应曲线的测定。分别比较中心与中心外固视眼矫正前后黄斑区域与全域视网膜的暗适应功能,以此和临床检查结 According to Xia Dezhao’s visual acuity analysis, there are optic nerve atrophy center and outside the two fixation state, as well as measuring the dark field of vision of patients with eccentric fixation, you must first line of sight to the dim point meter fixation target, and then by conventional measurement To ensure the correct measurement results reported, using Goldmann-Weekers dark adaptation meter and retrofit the instrument’s fixation lamp, to carry out the center and center fixation of optic nerve atrophy eye dark adaptation curve determination. Respectively, to compare the macular area of ​​central and exocentric fixation before and after correction of dark adaptation of the global retina, and clinical examination of the junction
