以计算机监视器作刺激屏，附加屈光系统，开发出计算机中心视野分析功能，测定：Ａ组５１例８１只正常眼３０°视野，Ｂ组４４例６７只正常眼生理盲点（ＰＢＳ），Ｃ组９０例１３６只患眼３０°视野。发现：Ａ组中３２眼无病理性暗点，４９眼平均出现２．２４个孤立暗点，ＰＢＳ水平径５．５６±１．１３°，垂直径６．６７±１．４１°。３组，ＰＢＳ水平径６．０４±１．１５°，垂直径７．３７±１．０２°。Ｃ组，阳性率为９３．３％。作者认为，该功能敏感性和特异性较高，具有临床实用价值。
A computer monitor was used as a stimulation screen and an additional refractive system to develop a computer center visual field analysis function. 51 eyes of 81 eyes of group A with 30 eyes of 81 eyes, 44 eyes of 67 eyes of group B with physiological blind spots (PBS), C Group 90 patients 136 eyes with 30 ° field of vision. It was found that there were no pathological dark spots in 32 eyes of group A, and 2.24 isolated dark spots appeared on average in 49 eyes. The horizontal diameter of PBS was 5.56 ± 1.13 ° and the vertical diameter was 6.67 ± 1.41 °. 3 groups, PBS level 6.04 ± 1.15 °, vertical diameter 7.37 ± 1.02 °. In group C, the positive rate was 93.3%. The authors believe that this feature is sensitive and specific, with clinical practical value.
