What should the nurse inform a client about the most common initial visual changes associated with glaucoma?

• A. Central vision is lost.
• B. Progressive tunnel vision occurs.
• C. Sudden flashes of light in the eyes.
• D. Eye floaters begin to be noticed.

Answer: (B)

Glaucoma causes optic nerve damage that affects peripheral vision first. The most common initial visual change is a gradual loss of peripheral fields, producing tunnel vision while central vision remains intact early on. This happens because the nerve fibers responsible for side vision are affected earlier in glaucoma. Since the change is painless and develops slowly, many people don’t notice it until it’s fairly advanced. Central vision loss tends to occur later, sudden flashes of light can indicate other conditions like retinal detachment or migraine, and floaters are usually age-related and not specific to glaucoma. Regular eye exams are important to detect these peripheral field changes early.
