Break Down the Problem

1. Identify the options related to the optic disc.
2. Determine which term is synonymous with the optic disc.

Relevant Concepts

• The optic disc is a part of the eye where the optic nerve meets the retina. It is known for being devoid of photoreceptors, which results in a blind spot in the visual field.

Analysis and Detail

1. Option A - Cornea: This is the transparent front part of the eye that covers the iris and pupil; it is not synonymous with the optic disc.
2. Option B - Blind spot: This directly refers to the absence of photoreceptors in the optic disc area, making this a valid synonym.
3. Option C - Fovea: This is a small depression in the retina where visual acuity is highest; it is not synonymous with the optic disc.
4. Option D - Macula: This is an area on the retina responsible for central vision; it is also not the same as the optic disc.

Verify and Summarize

The optic disc is scientifically recognized as the origin of the optic nerve and is often referred to as the blind spot, as it lacks photoreceptive cells and hence cannot detect light, leading to a blind spot in our visual field.

Final Answer

b. Blind spot
