HD-OCT effective during vitreoretinal, cataract surgery

FORT LAUDERDALE, Fla. — High-definition optical coherence tomography has intrasurgical benefits in vitreoretinal and cataract surgery, according to a presenter here.
Susanne Binder, MD, and colleagues in Vienna have been using the Zeiss Cirrus SD-OCT with HD-OCT software in retinal and cataract surgeries and have found a number of positive clinical contributions with the technology, as demonstrated in a poster at the Association for Research in Vision and Ophthalmology meeting.
"It can help you see, for example, if additional membrane peeling is necessary," Dr. Binder told Ocular Surgery News. "I use it in all types of retina surgeries, but I also have been using it in cataract surgeries. It's also helpful for having an estimation of surgically induced trauma to the retina and to learn about the fovea in the supine position."
The poster showed the HD-OCT has been used in eight pars plana vitrectomies, four macular hole surgeries, three proliferative diabetic retinopathy cases, silicone oil removal in two eyes and one primary retinal detachment.
The authors present an exciting study demonstrating intraoperative macular optical coherence tomography. Several brief series have been reported using hand-held spectral-domain OCT devices; this is one of the first reports of the use of an intraoperative OCT device mounted directly to the operating microscope. Intraoperative OCT imaging can give us insight into microstructural changes that occur immediately as a result of our surgical maneuvers, and intraoperative imaging of macular microanatomy may be able to aid surgical decision-making in select cases of macular holes, epiretinal membranes and vitreomacular traction. As the authors discuss, ultimately for this technology to be clinically useful, motion tracking technology, as well as methods for improvement in OCT signal intraoperatively, will likely be necessary.
