Ray-tracing combined with 3D-OCT provide new levels of retinal imaging clarity

PARIS — The integrated use of two imaging technologies creates astonishingly clear and detailed images of subtle structures of the vitreoretinal interface, according to a presenter here.
The Carl Zeiss Meditec Cirrus 3D-OCT has been integrated for use with the Maxon computer rendering and ray-tracing program Cinema 4D XL 10.5 Studio Bundle.
"This highly sophisticated system can be used to decide whether surgery is necessary or not, and to see morphological changes following surgery," Carl Glittenberg, MD, said here at the Euretina meeting preceding the European Society of Cataract and Refractive Surgeons meeting.
Dr. Glittenberg showed an example of how vitreoretinal traction lines, their exact location and their effect on the macula could be seen in one eye. In another case of successful pars plana vitrectomy and membrane peeling to remove traction on the retinal surface, a flat retina was visible and all traction forces had disappeared; however, three spots of residual membrane were visible, and could be a source of recurrence of the pathology, he said.
"None of these details could be visualized with other systems," Dr. Glittenberg said.
"At this stage, the rendering time of ray-traced reconstruction is too slow to be applicable on an everyday basis, but we are working at system that will be able to achieve this clarity in real time," he said.
