Question
Chapter 10, Problem 28RA
Summary Introduction
To review:
1. The reason behind the formation of clearer image on the fovea centralis than the periphery of the retina.
2. The higher sensitivity of the corners of the eyes to light than the fovea.
Introduction:
Fovea centralis is a pit that is present in the macula lutea of the retina. It provides clarity to vision. Rod and cone cells are present throughout the retina in different concentrations. Fovea centralis is the region where only cone cells are present. It does not contain rod cells.

Compare the architecture of the fovea centralis with more peripheral regions of the retina. How does this architecture relate to visual acuity and sensitivity?
Starting with the optic nerve, trace the action potential from the right temporal visual field to the visual cortex.
What is the possible effect of lesions of the visual pathway?
If your vision is normal and you put on your hyperopic friend’s glasses, is the focal point in front of your retina or behind it? (Hint: How does a lens that corrects hyperopia affect rays of light?)
