摘要
前言我们曾经提出了一种周边视野定量测量的新方法,即用固定的背景照明条件,以同一种大小和刺激强度的试标作周边视野检查。
A new method of quantitative measurement of central visual field is introduced in this article. It is the authors who firstly suggest that in mesopic condition the central visual field of 30°is assumed to be a cylinder, the roof of the cylinder is Greve's topographical units, the height of the cylinder is visual threshold sensitivity. To devide the roof of the cylinder into 120 parts and the height of the cylinder into 5 layers according to the differance of 4 decible, which is significant statisticlly. Then the cylinder is devided into 120×5 = 600 pieces. The authors suggested this new method and manufactured TBC-1 central visual field analyzer with the cooperation of others.The authors point out that this method of quantitative measurement of central visual field is very useful in many diseases, helpful to make diagnosis and to estimate the effect of treatment and prognosis.
