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

Choice A rationaleWithout treatment, glaucoma can lead to blindness due to the progressive damage it causes to the optic nerve. Elevated intraocular pressure damages the optic nerve fibers, leading to peripheral vision loss and eventually total blindness if untreated.Choice B rationaleDouble vision is not a common symptom of glaucoma. Instead, glaucoma typically presents with symptoms like gradual peripheral vision loss, eye pain, and halos around lights.Choice C rationaleGlaucoma is primarily caused by increased intraocular pressure, either due to overproduction of aqueous humor or improper drainage, not inadequate fluid production.Choice D rationaleUse of eye drops helps to control intraocular pressure but does not improve vision; it helps to prevent further damage to the optic nerve.
