The anterior segment of the eye consists of: conjunctiva, episclera, sclera, cornea and iris. It can also cause inflammation of the lacrimal pathways, eyelids and orbit.
The most common symptoms include eye pain, light sensitivity, impaired vision, tearing and redness of the eye.
Inflammation can be divided into sterile – non-infectious, with typically negative bacteriological cultures and infection caused by microorganisms – see Infection.
