THE FREQUENCY OF COLOUR-BLINDNESS IN XIBE NATIONALITY OF LIAONING

红绿色盲属于X连锁隐性遗传疾病。1988年5月采用俞自萍绘制的《色盲检查图》(1982年第四版,第九次印刷),对沈阳市市郊的锡伯族居民进行了调查。其中男789人,女630人,共计1419人。受检者年龄7—60岁。检查发现男性色盲(弱)40人,色盲率为5.07％。女性色盲(弱)2人,色盲率为0.32％。男性色盲率平方与女性色盲率之比为0.80。

In May 1988, using 《玊The test colour-blindness atlas》made by YU Zhi Ping (the fourth edition of 1982, the ninth print), we investigated the frequency of colour-blindness from Xibe Nationality inhabitants in Shenyang suburbs, among which 789 are males, 630 are females, totally 1419. The age of the examined people is 7-60 years old. We found male colour-blindness (weakness) in 40 persons, and the frequency of colour-blindness is 5.07 per cent; the female colour-blindness (weakness) in 2 persons, and the frequency of colour-blindness is 0.32 per cent.
