The nurse is performing an eye assessment on an 80-year-old patient. Which of these findings is considered abnormal?

A. Loss of the outer hair on the eyebrows attributable to a decrease in hair follicles: It is normal for older adults to experience changes in hair growth, including loss of eyebrow hair due to a decrease in hair follicles. This finding is considered a typical age-related change and not abnormal. B. Unequal pupillary constriction in response to light: This finding is considered abnormal and may indicate a potential neurological issue or damage to the optic or oculomotor nerves. Normal pupillary response should be equal and reactive to light, so any discrepancy in pupillary constriction warrants further evaluation. C. Decrease in tear production: A decrease in tear production is common in older adults due to age-related changes in lacrimal gland function. This condition, known as dry eye syndrome, is not considered abnormal for this age group. D. Presence of arcus senilis observed around the cornea: Arcus senilis is characterized by a gray or white ring around the cornea due to lipid deposits and is commonly seen in older adults. While it may indicate elevated cholesterol levels in younger individuals, its presence in elderly patients is usually not abnormal.
