keratoconjunctivitis sicca
Quick Summary
Keratoconjunctivitis sicca, also known as dry eye, is a condition characterized by dryness and inflammation of the cornea and conjunctiva. This dryness occurs due to insufficient tear production, which can be linked to autoimmune disorders or diseases affecting the tear glands. When dry eye is associated with other systemic disorders, it is referred to as Sjögren's syndrome.12
In some cases, the cornea can become dry and inflamed if a person is unable to fully close their eyelids, leading to exposure keratitis. Treatment typically involves aggressive eye lubrication, but more invasive measures like punctal closure or surgery may be necessary if lubrication fails. Keratitis, which is inflammation of the cornea, can lead to vision loss by clouding the cornea.1
