Central vision loss is a finding suggestive of:

Central vision loss specifically refers to a decrease in the ability to see fine details directly in front of you, which is primarily associated with issues affecting the macula, the central part of the retina responsible for sharp vision. Macular degeneration is a leading cause of central vision loss, particularly in older adults, as it gradually deteriorates the macula, leading to noticeable changes in central vision.

Cataracts, on the other hand, typically cause blurred vision more generally and can affect peripheral vision as well; the primary issue is clouding of the lens rather than specific damage to the central visual pathway. Glaucoma involves damage to the optic nerve that commonly affects peripheral vision first before later affecting central vision, but it is not characterized by immediate central vision loss.

Given these distinctions, macular degeneration is the most directly correlated with central vision loss, making it the best answer.
