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.
May 15, 2022 · At the point on the retina where the approximately 1 million axons converge on the optic nerve, there are no rods or cones. This spot, called the blind spot, is thus insensitive to light. Figure 15.9.3.2 Blind spot. You can demonstrate the presence of the blind spot.
Learning Objectives. 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 ...
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.
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. Figure 15.5.3 – Structure of the Eye: The sphere of the eye can be divided into anterior and posterior chambers ...

Oct 18, 2024 · 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. A scotoma may be a spot on the retina where your nerves don’t work or send signals to your brain.

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.
