RNFL stands for which retinal layer?

• A. Retinal Nerve Lamina
• B. Retinal Nerve Fiber Layer
• C. Retinal Nerve Fiber Layering
• D. Retinal Nerve Fiber Lamina

Answer: (B)

This question tests recognition of the standard name for the retinal layer that contains the axons of the retinal ganglion cells. The correct expansion is Retinal Nerve Fiber Layer. This layer sits just beneath the inner limiting membrane and above the ganglion cell layer, and it carries the unmyelinated axons that converge to form the optic nerve. In OCT, measuring its thickness around the optic nerve head is a primary way to detect nerve damage, since thinning signals loss of nerve fibers, such as in glaucoma. The other options use terms not used to name this layer (lamina or layering), so they don’t match the conventional anatomical designation.
