Is the Nuclear layer hyper reflective or hypo reflective?

Is the Nuclear layer hyper reflective or hypo reflective?

• A. Hyper reflective
• B. Hypo reflective
• C. Iso reflective
• D. Not visible

Answer: (B)

In OCT, how bright a layer looks depends on how much light it backscatters, which is tied to the tissue’s microstructure. Layers with many organized, fibrous or densely scattering components reflect more light and appear brighter (hyperreflective). Layers made of densely packed cell bodies with less organized scattering backlight less, so they appear darker (hypo-reflective). The Nuclear layer contains the cell bodies of neurons and tends to have less organized scatter compared with the surrounding layers that have more fibrous or layered structures. Because of this reduced backscatter, it shows up as a darker, hypo-reflective band on the OCT image.
