What is the nasal retina?

What is the nasal retina?

• A. The outer side of the retina, toward the temple.
• B. The inner side of the retina, toward the nose.
• C. The central area at the optic disc.
• D. The vascular layer of the retina.

Answer: (B)

The idea being tested is how we describe retinal regions by their orientation inside the eye. The retina can be divided into nasal (toward the nose, the medial side) and temporal (toward the temple) parts. The nasal retina is the portion closest to the nose—the medial or inner side of the retina. This helps distinguish it from the temporal retina and from other structures like the optic disc (the nerve head) and the vascular layer (the choroid). So the nasal retina is simply the part of the retina toward the nose.
