We'd love to hear more about what is visible light OCT and what unique information can it provide to us that standard structural, spectral domain, or swept source OCT cannot.

Sure, yeah, I can take that one.

So the OCT that clinicians are familiar with uses near-infrared light, and that's nominally light beyond the visible spectrum, 700 nanometers or above.

Typically, the patient can see the light, but it's very dim and reddish.

The visible light OCT uses wavelengths within the visible spectrum itself, so from 400 to 700 nanometers.

And in this particular instance, from about 500 nanometers to 650 nanometers is what we used to image for this case.

So why would we do this? So there are really two advantages here.

Is this something that may play a role in routine clinical practice? Or is it more going to be on the research side for us to understand more of the pathophysiology and how we can track patients longitudinally to really understand what happens in certain disease states? What do you see happening?
