Keratoconjunctivitis sicca (dry eye)

Abstract

Keratoconjuctivitis sicca, more commonly known as dry eye, or dry eye disease, is common. It results from improper functioning of the lacrimal functional unit. First-line treatment with tear substitutes, such as eye drops, gels and ointments, have an essential role. However, a newer understanding of the inflammatory aetiology of the disease has resulted in a shift in treatment strategies.
