Abstract
The anterior segment of the eye is a metabolically active system, which includes the ocular surface of the eye and extends posteriorly to the crystalline lens. Ocular surface diseases often disrupt the complex interplay of cornea, conjunctiva, meibomian glands, eyelids, and the lacrimal system, leading to diminished visual acuity and discomfort, and occasionally to frank pain. This can negatively impact the patient’s quality of life. Other anterior segment diseases including keratoconus, glaucoma, and cataract may also affect visual acuity. Oxidative stress and inflammation have been investigated in pathogenesis of these diseases. There has been an increase in the number of studies investigating various nutritional supplements benefiting the anterior segment structures. This review discusses the role of these supplements with supported clinical evidence.
