Adaptive Optics for Optical Coherence Tomography in Retinal Imaging: A Reflection on Past and Future Developments

摘要

OCT is a non-invasive technique for three-dimensional imaging at high axial resolution. Due to aberrations in the eye, OCT systems for retinal imaging have a limited lateral resolution. The lateral resolution can be increased by using adaptive optics (AO) to correct for static and dynamic wavefront aberrations. The combination of these two technologies results in high quality AO-OCT images to image photoreceptors, capillaries and nerve fiber bundles, which can help retinal specialists to better understand and diagnose retinal diseases. Here we review the basic principles of AO-OCT and discuss future opportunities for the technology.
