New OCT-A device allows imaging of nonsedated infants
FORT LAUDERDALE, Fla. — The development of a no-contact, handheld OCT-A probe has allowed the first images to be captured of nonsedated infants, according to a speaker here.
“It’s a real challenge to examine infants in clinic, let alone really image them. We came up with a unit that will allow us to image infants undergoing anesthesia. This particular unit is a portable, flex module that uses a modified tabletop system and is mounted on its armature. It can easily be pulled into the OR and image there. It allows us not only to obtain OCT, but OCTA, fluorescein angiography and ICG images which previously had not been used,” Lejla Vajzovic, MD, said at Retina World Congress.
Developed by Vajzovic and colleagues, the device successfully imagined 297 eyes of 178 pediatric patients, ranging from 3 weeks to 17 years of age. The researchers found 135 eyes of 89 patients without intraocular disease, but successfully captured images of diseased eyes that ranged from uveitis to familial exudative vitreoretinopathy, a hereditary disorder that results in the abnormal development of retinal blood vessels with an avascular retinal periphery, she said.
Pediatric OCT-A imaging can help screen patients for these hereditary diseases, reveal vascular abnormalities, and screen for vascular development, she noted.
Vajzovic and colleagues are currently developing a handheld device to successfully image pediatric patients in clinic. The handheld, noncontact OCT-A probe can be used in the operating room, in clinic, and the NICU to capture images, she said.
“We have a first handheld prototype for OCT-A probe. We are able to take this pretty much anywhere in the hospital to image some of the youngest patients we previously have not been able to image,” she said.
