Question: 1 / 400

What does the physiologic blind spot correlate with in the anatomy of the eye?

Cornea

Optic nerve

The physiologic blind spot corresponds to the area of the retina where the optic nerve exits the eye, known as the optic disc. In this specific region, there are no photoreceptors (rods or cones) to detect light, which results in a lack of visual perception in that small part of the visual field. When light falls on this area, it cannot be seen, leading to the phenomenon we refer to as the blind spot. This is a normal anatomical feature of the eye and important for understanding various visual field tests and the overall function of the visual system. The other options, such as the cornea, lens, and retina, do not create a blind spot as they contain photoreceptors or are designed for light transmission and focusing in the eye.
