A common pink or red eye refers specifically to a viral infection of the outermost layer of the eye, the conjunctiva. Infection or inflammation of the conjunctiva is known as a “conjunctivitis.” Conjunctivitis can cause watering of the eyes and mild discomfort, but will generally clear up without incident. Pink eye can also occur with other eye diseases that may require more active management to effectively resolve. We encourage all of our patients to visit our office as soon as possible when they, or their child, have a pink or red eye. Using special dyes and our biomicroscopes, our eye doctors can inspect the surface of the eyes and lids to accurately determine the cause of the disease. There is no eye drop that will treat every type of red eye, and knowing the cause of the patient’s disease will direct our treatment. Besides the common viral pink eye, bacterial infection, fungal infection, amoebic infection, ocular allergies, dry eye, ocular foreign bodies, meibomitis, blepharitis, and misdirected eyelashes can all cause red or pink-colored eyes.
