What is the result of decreased lacrimal function?

Decreased lacrimal function leads to insufficient tear production, which is crucial for maintaining tear film stability and eye surface health. When the lacrimal glands do not produce enough tears, the eye becomes dry, leading to conditions such as keratoconjunctivitis. This condition, often referred to as dry eye syndrome, is characterized by inflammation of both the cornea and the conjunctiva due to inadequate lubrication.

Inadequate tears result in symptoms such as discomfort, a gritty sensation in the eyes, redness, and in severe cases, can lead to damage to the corneal epithelium. Proper tear production is essential for protecting the eye from injury and infection, as well as providing clarity of vision. The other choices do not follow the physiological consequences of decreased lacrimal function; hence they do not relate to the effects of reduced tear production.
