New aspects in the laser treatment of glaucoma

Over 50 papers, appearing between October 1989 and September 1990, were reviewed. Among these, 17 were found to be of interest and 2 of outstanding interest. Structural and molecular effects and prevention of postcoagulative pressure rises are discussed under the category of argon laser trabeculoplasty. Papers concerning the size of laser iridotomies and the assessment of their success are also reviewed. A size of at least 150 to 200 mum is recommended. The majority of recommended papers concern parameters for cyclophotocoagulation, clinically and experimentally. Papers on the topic of sclerostomy include one presenting clinical results of treatment with a neodymium:yttrium-aluminum-garnet laser ab interno and another presenting experimental investigation of a partial external trabeculectomy using the excimer laser.
