摘　　要：目的　测定青年人眩光失能（ｇｌａｒｅ ｄｉｓａｂｉｌｉｔｙ ，ＧＤ） 值，并探讨其临床意义。方法　采用ＭＧＴ－ １ 多功能视觉眩光测试仪，测定３６ 名正常年青人７２ 眼的ＧＤ 值，单眼，双眼分别测定，目标亮度与眩光亮度设置为中－ 中及弱－ 中２ 档。结果　ＧＤ 值在中－ 中状态下，单眼为９１ ％ ，全距为０ ～３４０ ％ ，双眼为９３ ％ ，全距为０ ～３６ ％ ．弱－ 中状态下，单眼为２５０２ ％ ，全距为０ ～７１０ ％ ，双眼为２２９ ％ ，全距为４０ ％ ～４７０ ％ ．ＧＤ 值在同一状态下，单眼与双眼相比无显著差异，而在不同状态下，单眼与双眼差异显著。结论　正常年青人有一定的ＧＤ 值，不同状态下的ＧＤObjective To measure the glare disability(GD)values of youth and investigate the significance.Methods MGT-1 Multi-function visual glare tester was used.The GD values of 72eyes of 36 normal young people were measured The monocular and binocular GD values were measured respectively.The brightness of the target and glare were set middle-middle and weak-middle respectively.Results In middle-middle condition,monocular GD value was 9.13%(range 0-34%),binocular GD value was 22.94%(range 0～36%).In weak-middle condition,the monocular GD value was 25.02%(range 0～71%).binocular GD value was 22.94%(range 4～47%).IN the same condition,there was not significant difference between monocular and binocular GD values,but in different condition,the difference was significant.Conclusions There was some GD value for normal youth,but the GD value was different in different conditions.
