The client with glaucoma asks the nurse is complete vision will return. The most appropriate response is:

A. Telling the client vision will never return may cause unnecessary distress; the focus should be on management. B. Vision loss in glaucoma is typically permanent, not temporary, so this is inaccurate. C. Glaucoma causes irreversible damage to the optic nerve, but treatment can prevent further vision loss, which is the most accurate and supportive response. D. Medications help prevent progression but do not restore lost vision.
