What is the main function of the Henle fiber layer in the retina?

• A. Protecting the retina from external damage
• B. Regulating the amount of light entering the eye
• C. Transmitting visual signals to the brain
• D. Containing the cell nuclei of photoreceptors

Answer: (C)

The Henle fiber layer consists of the oblique axons of cone photoreceptors in the macula that radiate toward the outer plexiform layer. These fibers act as the conduits carrying signals from the photoreceptors to the next retinal neurons (bipolar and horizontal cells), which is the first major step in transmitting visual information deeper into the retina and onward to the brain. It’s not about protecting the retina, regulating light entry, or housing photoreceptor nuclei—the nuclei sit in a different layer.
