In OCT imaging, how is hypo-reflectivity indicated?

• A. As a bright white area
• B. As a dark or black area on the scan
• C. As a red color
• D. As a blue tint

Answer: (B)

Hypo-reflectivity shows up as a region that backscatters less light than its surroundings, so it appears darker on the OCT scan. OCT images are displayed in grayscale where brighter areas indicate higher reflectivity and darker areas indicate lower reflectivity. Therefore a dark or black area represents hypo-reflective tissue. This contrasts with hyper-reflective regions, which appear bright. In practice, fluids or edema often look hypo-reflective on OCT due to their lower scattering compared with surrounding tissue.
