TOKYO — The latest developments in optical coherence tomography technology have the potential to unveil features and monitor changes of the lamina cribrosa, the primary site of glaucoma-related axonal injury. “OCT imaging of the lamina cribrosa is challenging and has limitations. The posterior surface is difficult to see. The anterior is visible but in some cases obscured by prelaminar neuronal tissue,” Joel S. Schuman, MD, said at the World Ophthalmology Congress. Advancements in technology are progressively allowing better penetration of the tissue.
