"Long-Depth-Range Ophthalmic Imaging for Exploring Understudied Regions of the Human Eye"
Abstract: Advances in ophthalmic photonics have been dominated by high-resolution modalities optimized for individual ocular structures. However, many clinically relevant processes—including ocular growth, biomechanical remodeling, and tissue degeneration—span the entire optical path of the eye and remain insufficiently characterized by conventional ophthalmic modalities. Recent advances in photonics technologies have enabled long-depth-range optical imaging allowing for visualization and quantitative analysis of ocular tissues from the anterior segment to the retina within a single measurement. In this presentation, we discuss recent developments facilitating long-depth-range imaging including new tunable light sources, high-speed electronics and tunable optics. We will introduce novel application enabling imaging low-scattering tissues such as vitreous humor. We will also demonstrate how extended axial coverage and advances signal processing can be leveraged to probe intrinsic optical properties of ocular tissues, including light scattering in the crystalline lens and in the vitreous body. The capabilities shown in this talk open new avenues for studying whole-eye optics, tissue biomechanics, and disease progression, while supporting future integration with multimodal photonic techniques and computational modeling.
