Joel Pearlman, MD, PhD Retina 2015: What You Need to Know to Impress Your Friends, Colleagues and Patients SVOS Tahoe 2015 After a brief discussion about the past 100 years of retinal imaging, from the development of the indirect ophthalmoscope to the invention of fundus photography and fluorescein angiography, we will take a deep dive into the everevolving world of optical coherence tomography – where we have gotten diagnostically in the past 10 years and where we might expect this technology to take us in the next ten. Particular attention will be given to the types of OCT artifacts that commonly arise and how to avoid them as well as common clinical and some research applications.
