A nurse is collecting data from a client who has macular degeneration. Which of the following findings should the nurse expect?

Macular degeneration is a progressive eye disorder that affects the macula, the central portion of the retina responsible for sharp, detailed vision. It is a leading cause of vision loss in older adults and primarily impacts the ability to see fine details needed for reading, driving, and recognizing faces. The condition typically progresses slowly and is not associated with pain. Nurses focus on identifying characteristic visual changes to support early intervention and safety planning. Rationale: A. Sharp pain is not associated with macular degeneration because the condition affects the retina, which lacks pain receptors. Patients typically do not experience discomfort; instead, they notice gradual visual changes. Pain would suggest other ocular conditions such as acute glaucoma or infection. B. Astigmatism is a refractive error caused by an irregular curvature of the cornea or lens, leading to blurred or distorted vision at all distances. It is unrelated to macular degeneration, which specifically affects central retinal function rather than corneal shape. C. Loss of central vision is the hallmark finding in macular degeneration due to degeneration of the macula. Patients often report difficulty reading, recognizing faces, or seeing fine details while peripheral vision remains intact. This central vision loss significantly impacts daily functioning. D. Nystagmus is characterized by involuntary rhythmic eye movements and is typically associated with neurological disorders, vestibular dysfunction, or congenital conditions. It is not a characteristic finding of macular degeneration, which primarily affects visual acuity rather than eye movement control.
