Answer :
Final answer:
The eye disorder in question is glaucoma, which can lead to peripheral vision loss and eventually tunnel vision due to optic nerve damage.
Explanation:
The eye disorder that would likely be observed on the chart of an elderly person experiencing a gradual loss of peripheral vision resulting in tunnel vision is glaucoma. Glaucoma is a group of eye conditions that damage the optic nerve, which is essential for good vision and often caused by abnormally high pressure in the eye. This damage can lead to loss of vision if not treated. The process of this loss usually starts with the peripheral vision, potentially progressing to tunnel vision as the condition worsens.
