Optical Coherence Tomography (OCT) C Fundamentals Practice Test

RNFL segments are commonly referred to as what?

Bundles Fibers Strands Layers

Correct Answer:

Bundles

Explanation:

The retinal nerve fiber layer is made up of axons from retinal ganglion cells that travel together in organized groups. These groups are called nerve fiber bundles, so when we refer to RNFL segments, the standard term is bundles because it reflects the way the fibers are bundled together rather than describing individual fibers or simply labeling it as a separate layer. Using bundles emphasizes the collective arrangement of the axons, which is how the RNFL is structurally organized in both histology and OCT terminology.
