Color contrast sensitivity was measured in laser operators before and after laser sessions. The tritan threshold was elevated after the sessions in all laser operators who had used argon (blue-green) lasers. No change was observed when lasers with longer wave-lengths were used. Elevation of the tritan threshold to above-normal levels was observed even before laser sessions. The thresholds remained increased even when the laser operator did not use a laser for 3 weeks. Thus, it appears that the damage caused by the argon blue-green laser is cumulative. Elevated tritan thresholds were also observed in patients with peripheral retinal breaks who were treated with an argon (blue-green) laser.
在激光治疗前后对激光操作人员进行了颜色对比敏感度测量。在所有使用氩（蓝绿色）激光的激光操作人员中，治疗后蓝黄色阈值升高。使用波长较长的激光时未观察到变化。甚至在激光治疗前就观察到蓝黄色阈值升高到高于正常水平。即使激光操作人员3周未使用激光，阈值仍保持升高。因此，看来氩蓝绿色激光造成的损害是累积性的。在用氩（蓝绿色）激光治疗的周边视网膜裂孔患者中也观察到蓝黄色阈值升高。
