Trabectome-only surgery more successful in patients with pseudoexfoliation, few medications

WASHINGTON — A study associated pseudoexfoliation glaucoma and patients on a low number of glaucoma medications with successful outcomes in Trabectome-only surgery, according to a presentation here.
In a poster presentation at the American Glaucoma Society meeting, Nils Loewen, MD, PhD, and colleagues studied 594 glaucoma patients undergoing Trabectome-only surgery (NeoMedix). A multivariate analysis found pseudoexfoliation glaucoma patients had a 60% lower risk of failure than primary open-angle glaucoma patients. Similarly, patients on one more glaucoma medication had a 40% higher risk of failure than those with one less medication, according to the authors.
“In our study, Trabectome-only populations were selected to identify risk factors since Trabectome with cataract surgery had very low failures to allow identification of risk factors,” the authors said.
Failure in the study was identified as an IOP higher than 21 mm Hg, IOP reduction of less than 20% on two consecutive follow-up visits after 3 months and the need for a second surgery.
