    Improving Access—but Not Outcomes—With Iris Optical Coherence Tomography Angiography

    Throughout the past 2 decades, the exquisite, real-time ocular imaging attainable with optical coherence tomography (OCT) has transformed the practice of ophthalmology. Further increases in processing speed have led to the introduction of OCT angiography (OCT-A). 1 Preliminary work has shown that it is possible to use OCT-A to characterize the vasculature of the iris. 1 The current standard for assessing anterior segment circulation is iris angiography, but this approach has substantial drawbacks, most notably the need to administer an intravenous contrast agent, such as fluorescein or indocyanine green.
