• 3-D Visualization of the Posterior Vitreous With OCT and AI


    During Retina Subspecialty Day’s “Imaging” session (Ret05V), Kyoko Ohno-Matsui, MD, PhD, shared images obtained with a combination of ultra-widefield optical coherence tomography (OCT) and artificial intelligence (AI).

    Deep learning. OCT images of the posterior vitreous were obtained in the axial, coronal, and sagittal planes. Manual segmentation was performed every 10 frames, and AI segmentation was performed every frame. The combination provided 3-D visualization of vitreous structures that Dr. Ohno-Matsui characterized as “pockets” and “cisterns.”

    Clinical application? “Using this technology, complicated vitreous structures—and how they relate to the development of vitreoretinal diseases” will eventually be clarified, Dr. Ohno-Matsui said.

    In the chat function of the presentation, one retina specialist commented, “I wish we could do this when planning diabetic surgery; there would be no vitreous adhesion surprises.” —Jean Shaw
