SLT yields similar outcomes in first and second eyes

FORT LAUDERDALE, Fla. — The outcome of selective laser trabeculoplasty in the first eye may predict the outcome in the second eye, according to a poster presented at the Association for Research in Vision and Ophthalmology meeting here.

Seung Youn Jea, MD, and colleagues aimed to assess the correlation between SLT outcomes in the first eye and those in the second eye.

"If there is a poor response to SLT in one eye, greater baseline anti-glaucoma medications, higher baseline IOP and higher laser power were associated with a greater chance of success," Dr. Jea and colleagues said. "Higher treatment energy may be helpful to obtain better outcomes when applying SLT to the contralateral eye."

The retrospective study included 178 eyes of 89 patients who underwent SLT between 2002 and 2008. Success was defined as a decrease in IOP of at least 3 mm Hg sustained through final follow-up without additional medications or further surgical intervention.

Study results showed that 67 patients (75.3%) had the same result in the first eye and contralateral eye and that 22 patients had different results in the two eyes.

Data showed that pre-treatment number of medications and SLT energy correlated with a higher likelihood of success, the authors said.
