The daughter of an elderly client diagnosed with macular degeneration asks the nurse to explain this disorder.In formulating a response, the nurse would include information that this condition is characterized by which of the following?

Choice A rationaleSeparation of the retina from the choroid, also known as retinal detachment, is a different condition altogether. Retinal detachment can cause vision loss but is not related to macular degeneration. This condition often requires immediate medical attention to prevent permanent vision loss and is typically characterized by the sudden appearance of floaters, flashes of light, and a shadow or curtain over a portion of the visual field.Choice B rationalePeripheral vision loss and seeing halos around light are more commonly associated with conditions like glaucoma. Glaucoma involves increased intraocular pressure, which can damage the optic nerve and lead to peripheral vision loss and seeing halos around lights. This condition can be managed with medications or surgery to lower intraocular pressure and prevent further vision loss.Choice C rationaleComplaints of severe pain and pressure in the eye are indicative of acute angle-closure glaucoma. This is a medical emergency and requires prompt treatment to reduce intraocular pressure and prevent optic nerve damage. The symptoms of acute angle-closure glaucoma are sudden and severe and can include headache, nausea, and vomiting, along with the eye pain and pressure.Choice D rationaleCentral vision loss with intact peripheral vision is characteristic of macular degeneration, particularly age-related macular degeneration (AMD). AMD affects the macula, the part of the retina responsible for sharp, central vision. As the macula deteriorates, central vision becomes blurry or wavy, making it difficult to read, drive, or recognize faces, while peripheral vision remains largely unaffected.
