NEW ORLEANS — Electroretinograms can help predict progression of diabetic retinopathy, age-related macular degeneration and glaucoma by providing objective information about visual function, according to Nate Lighthizer, OD, at Academy ’23.
“It’s something that has changed tremendously over the course of the last 10 to 15 years,” Lighthizer, associate dean and professor at NSU Oklahoma College of Optometry, told Healio.
According to Lighthizer, electroretinograms (ERGs) can be performed in roughly 30 seconds and provide objective data on visual function as opposed to visual field tests, which are subjective.
“It has really emerged as an office-based procedure, an office-based diagnostic test,” Lighthizer said. “ERGs are now handheld devices. They can be laptop versions that are much more affordable for the practice, much more doctor-friendly, staff-friendly and, most importantly, patient-friendly.”
