Final answer:
The nurse should expect a client with a detached retina to report symptoms like flashes of light, a 'curtain' over part of their vision, or sudden decrease in vision, particularly loss of peripheral vision, rather than problems seeing different colors.
Step-by-step explanation:
When assessing a client who has a detached retina, a nurse should expect the client to report experiencing symptoms such as flashes of light, a "curtain" over part of their field of vision, or a sudden decrease in vision. A person with a detached retina may describe a shadow or blackness on one side of their vision (peripheral vision) that is persistent and does not resolve. It is caused by the retina at the back of the eye pulling away from the layer of blood vessels that provide it with oxygen and nutrients. Loss of peripheral vision, rather than issues with color vision, is the hallmark symptom of retinal detachment.
A detached retina can significantly impair vision and is considered a medical emergency. It requires prompt medical attention to prevent permanent vision loss. Color perception is less likely to be affected immediately, unless there are associated macular changes or damage. Laser surgery can sometimes be used to repair a detached retina by creating scar tissue that holds the retina in place, as shown in various medical illustrations and discussed in medical texts. The laser used in this surgery is focused through the lens of the eye to a specific point on the retina (Figure 30.40), while the patient's vision must be relaxed in order for the retinal laser treatment to be accurate and effective.
