视野面积的数字化,对于精确定量分析视野范围变化,早期发现青光眼视野损害是很有意义的。国外研究者对视野面积数字化方法的研究表现了浓厚的兴趣。过去,一直用手工面积求积仪测算视野面积,精确度不够高,影响因素较多,误差范围较大。最近,国外设计制造出的电脑控制视野面积测算系统和我校引进的IBM电子计算机数字图像 The digitization of the visual field area is of great significance for the precise quantitative analysis of visual field changes and early detection of glaucomatous visual field damage. Foreign researchers showed a keen interest in the study of digitization of field of view. In the past, manual area plotter has been used to measure the visual area, the accuracy is not high enough, more factors, larger error range. Recently, the design and manufacture of computer control field of view area measurement system and our school introduced IBM digital computer image
