In OCT imaging, a hyper reflective layer would usually appear as which relative brightness compared with surrounding tissue?

• A. Brighter than surrounding tissue
• B. Darker than surrounding tissue
• C. Same brightness
• D. Not visible

Answer: (A)

In OCT images, brightness reflects how much light is backscattered from a tissue region. A hyperreflective layer has higher optical scattering, so it sends more light back to the detector than the surrounding tissue. That makes it stand out as a brighter region on the image. So the correct interpretation is that a hyperreflective layer appears brighter than surrounding tissue. If it were darker, it would be hyporeflective; if it had the same brightness, there would be no contrast; and if it were not visible, its signal would be too weak to detect.
