How does the outer nuclear layer appear on an OCT scan in terms of color?

Explanation:
OCT images map tissue reflectivity in grayscale: brighter areas are highly reflective, darker areas reflect less light. The outer nuclear layer consists of photoreceptor cell bodies and backscatters light less than the brightly reflecting layers nearby, so it appears as a hypo-reflective band. It isn’t completely black because some backscatter remains, but it isn’t bright either. That places it as a dark medium gray on the image.
