Question 37

Macular degeneration

Degeneration of the center of the retina that occurs as adults age is known as macular degeneration. This condition specifically affects the macula, which is responsible for sharp, central vision.

A) Total loss of vision

Total loss of vision may occur as a result of various eye diseases, but it is not a direct outcome of macular degeneration alone. While macular degeneration can lead to significant vision impairment, it does not necessarily result in complete loss of vision, as peripheral vision often remains intact.

B) Macular degeneration

Macular degeneration is the correct answer as it specifically refers to the degeneration of the macula, which is the central part of the retina. This condition is common in older adults and can lead to blurred or reduced central vision, making it difficult to read or recognize faces.

C) Formation of glaucoma

Glaucoma is a separate eye condition characterized by increased pressure in the eye, leading to damage of the optic nerve. While aging can increase the risk of glaucoma, it is not a direct result of degeneration of the retina and does not specifically relate to the central vision impairment seen in macular degeneration.

D) Formation of cataracts

Cataracts involve the clouding of the lens of the eye and are also related to aging. However, they do not directly result from degeneration of the retina nor do they specifically affect the center of vision like macular degeneration does.

Conclusion

Macular degeneration is the only option that directly addresses the degeneration of the center of the retina associated with aging. Other options, while related to vision impairment, do not specifically pertain to the degeneration of the macula, highlighting why macular degeneration is the accurate answer to the question posed.
