"The problem with narrow-angle glaucoma is that it's sometimes difficult to diagnose," said Dr. Robert Cykiert, an associate professor of ophthalmology at New York University Langone Medical Center in New York City. "You have to apply a special lens to diagnose narrow-angle glaucoma, [but] when we apply this lens, we're changing the anatomy of the eye. Sometimes we change the appearance of the angle. You can't be sure of the diagnosis because part of the examination is actually changing what you're looking at."
Currently, doctors use lasers to cut an opening in the iris to reduce the risk for a sudden attack.
FDOCT, by contrast "shines a light in a special infrared frequency onto the eye," Cykiert explained. "That's connected to a computer which does a very highly sophisticated analysis of how the light penetrates the eye."
"It's an imaging device that allows us to image the eye without cutting," Iwach added. "The nice thing is it doesn't touch the eye."
Beyond that, the technology will enable physicians to standardize or quantify changes in the eye and also visualize other structures in the eye that may have problems.
