LAS VEGAS — Frequency doubling technology is an “excellent screening tool for a glaucoma suspect,” according to one speaker here at the OSN Las Vegas meeting.

“This matrix perimetry is a step forward in screening patients for ocular hypertension,” Steven T. Simmons, MD, said. He said that frequency doubling technology, or FDT, is a valuable tool for following patients with early glaucoma and helps in tracking the progression of the disease.

FDT has shown an “improved ability to detect the progression” of glaucoma, he said. It can also help ophthalmologists identify patients “who are more likely to develop significant defects,” he said.
