Which of the following is a potential consequence of untreated glaucoma?

1. Improved night vision

2. Loss of peripheral vision

3. Increased color perception

4. Enhanced depth perception

The correct answer is: Loss of peripheral vision

Untreated glaucoma can lead to significant visual impairment, primarily affecting peripheral vision. This occurs because glaucoma involves damage to the optic nerve, often due to increased intraocular pressure. As the condition progresses, individuals may experience a gradual loss of their side vision, which can make it increasingly difficult to detect objects or movement outside of their central line of sight. This kind of vision loss is insidious, typically going unnoticed until it reaches an advanced stage, leading to tunnel vision or even blindness if left unchecked. In contrast, the other options present outcomes that are not typically associated with glaucoma. For instance, improved night vision, increased color perception, and enhanced depth perception are not changes you would expect in someone developing or living with the effects of untreated glaucoma. These functions may actually be compromised due to the overall decline in visual capabilities associated with the disease.
