Photoacoustic Imaging of the Eye

Photoacoustic Imaging of the Eye

Imaging plays a critical role in the evaluation of the eye, particularly retinal and choroidal pathophysiology in health and disease. The eye is currently undergoing a clinical imaging revolution with significant improvements that have occurred both in hardware, such as lasers and optics, in addition to software image analysis and automated deep neural network interpretation or image enhancement. In this webinar hosted by the OSA Therapeutic Laser Applications Technical Group, Dr. Yannis Paulus of the University of Michigan will explore a new hybrid optical-acoustic imaging modality called photoacoustic imaging. Photoacoustics have particularly useful applications in the eye and can provide both anatomic and functional eye evaluation. Many eye diseases, including macular degeneration and diabetic retinopathy, involve vascular abnormalities, which can readily be visualized with photoacoustic imaging. Multimodality eye imaging platforms have also been successfully developed to combine photoacoustic imaging with optical coherence tomography and fluorescence microscopy. Dr. Paulus will discuss the potential of photoacoustic imaging for molecular imaging. In addition, the potential application of photoacoustic imaging of the eye in both research and clinical diagnosis are comprehensively discussed as a powerful technique to visualize eye diseases.

What You Will Learn:

  • To describe the photoacoustic effect 
  • Evaluate eye diseases where photoacoustic imaging can provide important information 
  • Describe multimodality imaging of the eye and unique advantages and disadvantages of different modalities, including photoacoustic imaging, optical coherence tomography, and fluorescence microscopy 
  • Describe unique advantages of photoacoustic molecular imaging and how it could be used to better monitor and diagnose eye diseases 

Who Should Attend:

  • Engineers, physicists, biologists, chemists, and physicians interested in biomedical imaging and laser applications.

Yannis M. Paulus, M.D., F.A.C.S, is an academic vitreoretinal surgeon and clinician scientist that applies biomedical engineering, photonics, optics, lasers, physics, and nanoparticles to develop novel retinal imaging and laser treatment systems. He is an Assistant Professor at the University of Michigan, Department of Ophthalmology and Visual Sciences, and Department of Biomedical Engineering. He completed his undergraduate in chemistry and physics at Harvard University, medical school and ophthalmology residency at Stanford University Byers Eye Institute, and surgical and medical retina fellowship at Johns Hopkins University Wilmer Eye Institute. He directs a multidisciplinary, diverse laboratory dedicated to improving the vision of patients suffering from eye diseases. He has received entrepreneurship awards and patents, published more than 85 peer-reviewed publications and 6 book chapters, and consulted for medical devices and co-founded two retinal imaging start-up companies.
