A nurse is caring for a client who reports a decrease in central vision. The nurse should identify that this is a manifestation of which of the following visual impairments?

A. Macular degeneration: This is a leading cause of vision loss in older adults and typically results in the loss of central vision, making it difficult to read or recognize faces. B. Diabetic retinopathy: This condition affects the retina but typically causes changes in peripheral vision or blurry vision, not a specific loss of central vision. C. Glaucoma: Glaucoma often leads to peripheral vision loss, not central vision loss. D. Cataracts: Cataracts cause cloudy or blurry vision, but not a specific decrease in central vision.
