静态视野定量检查法,就是让病人在一定背景亮度的明适应条件下,用静止不动的光视标在视野某一根或几根子午线上进行检查。用不同亮度的固定视标测出的各点的灵敏度阈值,从而画出一条曲线,构成立体视野剖面图,对视野的深度作出定量分析,并准确地表达视网膜功能的程度。因此,它较一般动态视野检查法有较大的优越性。一、检查前病人的准备1.先查视力、眼底及裂隙灯检查,除外不能作静态视野检查之病例,视力要求在0.1以上,屈光不正者须矫正视力。2.检查前了解病人的病情及配合程
Static visual field quantitative examination, is to allow patients to a certain background brightness under the conditions of adaptation, with a stationary optometric standard in the field of vision of a root or a few radial on the check. With different brightness of the fixed target as the measured sensitivity threshold of each point to draw a curve to form a three-dimensional cross-sectional view of the field of view to make a quantitative analysis of the depth and accurate expression of the degree of retinal function. Therefore, it has more advantages than the general dynamic field of vision. First, check the preparation before the patient 1. First check the visual acuity, fundus and slit lamp examination, except for cases of static visual field examination, visual acuity requirements of 0.1 or more, refractive errors to be corrected visual acuity. 2 check before understanding the patient’s condition and with the process
