A nurse is providing education for a client who has glaucoma. Which of the following statements should the nurse include in the teaching?

A. "Without treatment, glaucoma can cause blindness.": Glaucoma leads to progressive optic nerve damage from increased intraocular pressure. If untreated, it causes irreversible vision loss and eventual blindness. B. "Double vision is a common symptom of glaucoma.": Diplopia is not typical of glaucoma. Instead, glaucoma often presents with peripheral vision loss, eye pain, halos around lights, or gradual vision changes. C. "Use of eye drops will improve vision over time.": Glaucoma medications, such as prostaglandin analogs or beta blockers, do not restore lost vision. They lower intraocular pressure to slow disease progression and preserve remaining vision. D. "Glaucoma is caused by inadequate production of fluid within the eye.": Glaucoma usually results from impaired drainage of aqueous humor, not decreased production. Blocked outflow raises intraocular pressure, damaging the optic nerve.
