Ulceration of the cornea
In severe cases of untreated dry eye syndrome, the associated inflammation (redness and swelling) can damage the surface of the cornea (the transparent layer at the front of the eye). This is called keratitis.
Keratitis can lead to scarring (ulceration), which could result in some disruption of your vision.
Conjunctivitis
Conjunctivitis is inflammation of the conjunctiva (the transparent layer of cells that covers the white part of the eyeball and the inner surfaces of the eyelids)
Most cases of conjunctivitis that are caused by dry eye syndrome are mild and do not need specific treatment. However, if you have conjunctivitis that becomes severe and chronic (long-term), seek treatment advice from a specialist.
See the Health A-Z topics about Allergic conjunctivitis and Infective conjunctivitis for more information about these conditions and how they are treated.
