Which condition experiences vision loss that begins in peripheral vision and may lead to total blindness?

• A. Macular degeneration
• B. Cataracts
• C. Glaucoma
• D. Presbyopia

Answer: (C)

The condition that experiences vision loss that begins in peripheral vision and may lead to total blindness is glaucoma. This eye disease is characterized by increased intraocular pressure, which can damage the optic nerve. As the disease progresses, individuals typically first experience loss of peripheral vision—a condition known as tunnel vision. If left untreated, this can eventually lead to complete vision loss, making it a serious condition requiring timely diagnosis and management.

In contrast, macular degeneration primarily affects central vision, impacting the ability to see fine details and causing difficulties with tasks such as reading. Cataracts cause clouding of the lens, resulting in blurry vision, but they do not specifically lead to peripheral vision loss. Presbyopia is an age-related condition that affects the ability to focus on close objects, but it does not cause peripheral vision loss or lead to blindness.
