—In the April Archives Feller and Weinreb1 reported the transient alteration of the blood-aqueous barrier after laser trabeculoplasty in 17 patients. They showed significant differences between treated eyes and control eyes in the amount of fluorescein leakage. Unfortunately, no information was provided on the preoperative conditions of the patients in the study. I am particularly interested in the number of patients who were black and the preoperative medication of the group. It has been my own clinical impression that iritis tends to develop in black patients after laser trabeculoplasty more often than in white patients, and for a more prolonged period. In addition, certain topical medications are more inflammatogenic. The results reported may help in confirming my impression and suggest further investigation into the breakdown of the blood-aqueous barrier after laser trabeculoplasty.
