When conducting an assessment of an older patient's eyes, you expect to see which of the following normal age-related changes of the external eye? (Select all that apply.)

A. Ectropion, where the lower eyelid turns outward, is a common age-related change due to weakened eyelid muscles. B. While dry eyes can occur with age, this is not always considered a normal part of aging—it may indicate dry eye syndrome and warrant treatment. C. Eyelid drooping and loss of elasticity (dermatochalasis) are normal changes that occur as the skin loses collagen and tone with age. D. Incomplete eyelid closure (lagophthalmos) can occur due to muscle weakness, a normal age-related change, which may increase the risk of dry eyes and irritation. E. Loss of eyelashes is not a typical or expected age-related change; while lashes may become thinner or lighter, significant loss is not considered normal and may indicate another condition.
