Oct 18, 2024 · What Can Cause a Blind Spot in Your Eye? Not all blind spots are normal. A noticeable blind spot that interferes with everyday activities like reading or driving may be a scotoma. Typically the optic nerve passes electrical signals into your brain to create a visual image.

6.1.1 Describe the region of the electromagnetic spectrum that is perceived by our visual system, and the relative energy of photons at long and short wavelengths. 6.1.2 Describe the major parts of the eye and their role in focusing light to create a clear image. In this section, we will meet the range of the electromagnetic energy spectrum ...
This creates a “blind spot” in the retina, and a corresponding blind spot in our visual field. Note that the photoreceptors in the retina (rods and cones) are located behind the axons, RGCs, bipolar cells, and retinal blood vessels. A significant amount of light is absorbed by these structures before the light reaches the photoreceptor cells.
Jul 27, 2023 · The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. It begins at the retina and terminates at the primary visual cortex (with several intercortical tracts).

Jan 18, 2023 · A scotoma may be a spot on the retina where the nerves don’t work and don’t send signals to your brain. There’s an abnormality in your field of vision: you temporarily or permanently can’t see as well or can’t see at all in a certain location. A scotoma can happen with conditions that affect your optic nerve or certain areas in the brain.

What causes a blind spot in the eye?
Because these axons pass through the retina, there are no photoreceptors at the very back of the eye, where the optic nerve begins. This creates a “blind spot” in the retina, and a corresponding blind spot in our visual field.
