On OCT scans, serous fluid appears as which color?

Explanation:
On OCT scans, image contrast comes from how much light is backscattered by different tissues. Dense or highly reflective structures return more signal and look bright (toward white), while areas with little backscatter appear dark. Serous fluid is a clear, low-scattering medium with minimal internal structure, so it sends back very little light to the detector. That makes it show up as a dark, or black, region on the OCT image.
