A client with age-related macular degeneration (AMD) is undergoing photodynamic therapy with the medication Verteporfin. What should the nurse include in the discharge teaching for this client?

A. Loss of peripheral vision is a hallmark sign of primary open-angle glaucoma. In POAG, increased intraocular pressure causes damage to the optic nerve, leading to a gradual loss of peripheral vision. This vision loss is often subtle and progresses slowly, making it difficult for individuals to notice until the condition is advanced.

B. Opacity of the lens is characteristic of cataracts, not glaucoma. Cataracts involve the clouding of the eye's natural lens, which leads to blurred vision and difficulties with seeing clearly, particularly in bright light. While cataracts and glaucoma can occur simultaneously, opacity of the lens is not indicative of POAG.
C. Decrease in color perception can be associated with various eye conditions, including age-related macular degeneration (AMD) and certain types of retinal diseases. While it can occur in glaucoma as the disease progresses, it is not the primary or most characteristic sign of POAG.
D. Pain and purulent discharge are more associated with acute conditions such as conjunctivitis (pink eye) or an eye infection, rather than primary open-angle glaucoma. POAG typically presents without pain or discharge, as it is a chronic condition with a gradual onset of symptoms.

A. Phacoemulsification is a procedure used to remove cataracts from the eye. It involves using ultrasound waves to break up the cloudy lens (cataract) into small fragments, which are then suctioned out. While this procedure is relevant for cataract treatment, it does not address the acute management of angle-closure glaucoma.
B. Extracapsular cataract extraction is a surgical procedure to remove a cataract from the eye by making an incision and extracting the lens in one piece or in large segments. Like phacoemulsification, this procedure is focused on cataract removal and does not directly treat the underlying issue of acute angle-closure glaucoma.
C. A cochlear implant is a device used to provide a sense of sound to individuals with severe hearing loss or deafness. This procedure is unrelated to the treatment of eye conditions or intraocular pressure and therefore is not appropriate for managing primary angle-closure glaucoma.
D. Surgical iridectomy is a procedure specifically aimed at treating angle-closure glaucoma. It involves creating a small hole (iridectomy) in the peripheral iris to allow aqueous humor to flow from the posterior chamber of the eye to the anterior chamber, bypassing the obstructed drainage angle.
