Glaucoma lasers: a review of the newer techniques

Purpose of review This paper serves to review the safety and efficacy of new laser techniques for the treatment of glaucoma with emphasis on those studies published within the past year. Recent findings Recently published studies have reinforced the strong safety profile, and efficacy of selective laser trabeculoplasty (SLT). Endoscopic photocoagulation, while more technically challenging and more invasive, offers several advantages over transcleral cyclophotocoagulation including direct observation of treatment and therefore, fewer complications. Laser goniopuncture is a fledgling technology with, thus far, a good safety profile, and benefits that include conjunctival sparing and good treatment response. Many unanswered questions remain including long-term success rates and ideal treatment parameters. Summary The benefits of laser in the treatment of glaucoma have been well established, and while some techniques will add to the ophthalmologists' armamentarium, others will fall into disuse as the efficacy and safety profiles of these procedures become recognized. Novel laser modalities, as well as the more traditional ones, require continued evaluation to further refine treatment parameters and to determine their long-term benefits.
