A select population of patients received repeat laser trabeculoplasties of 40 to 100 burns over 180 to 360 degrees. These eyes had shown an excellent prolonged response to initial laser trabeculoplasty. Eight of 11 eyes with greater than one year follow-up showed a sustained hypotensive response to repeat laser trabeculoplasty. No significant posttreatment intraocular pressure increases were observed. Repeat argon laser trabeculoplasty was effective for these patients who had shown a prolonged response to their initial treatment.
