Anterior segment OCT may help predict which patients are steroid responders
CHICAGO — Anterior segment optical coherence tomography may help predict which patients are at risk for being steroid responders following an intravitreal implant of dexamethasone, a physician said here.
“Non-steroid responders had a strong correlation” between fellow eye measurements in treated vs. untreated eyes, Michael A. Singer, MD, said at Retina Subspecialty Day preceding the joint meeting of the American Academy of Ophthalmology and Asia Pacific Academy of Ophthalmology. “The steroid responders were a little different. There was a strong significant correlation between the angle recess ... [and] intraocular pressure.”

In a retrospective study of 34 patients, 20 patients had glaucoma and 21 patients were pseudophakic.
Study results showed that pseudophakia was correlated to a larger angle recess in non-steroid responders (P = .0064).
In steroid responders, a higher IOP was correlated to a wider angle recess (P = .0085).
According to Singer, selective laser trabeculoplasty may be a way to help treat this condition.
“A three-dimensional view of the recess angle on a 3-D OCT before and after SLT shows that angle recess increases,” he said.
The development of specialized measurement software to properly measure angle recess space would also help to predict at-risk patients, Singer said.
