What should you know about flu conjunctivitis treatment?

A viral illness can inflame the thin surface covering the eye, causing redness, watering, irritation, discharge or sensitivity to light. Viral conjunctivitis can spread through contaminated hands, towels and shared cosmetics. Eye discharge that is thick or repeatedly returns may have another cause, so its appearance alone cannot identify the infection.

Treatment depends on the examination and the wider symptoms. Antibiotics do not treat viruses, but a clinician may prescribe antibiotic treatment when findings suggest a bacterial infection or another condition needs cover. Avoid using leftover eye drops, especially drops containing steroids, unless prescribed.

Wash hands before and after touching the eyes, avoid rubbing them, and use a clean warm or cool compress for comfort. Do not share towels, pillows, eye makeup or contact lenses. Stop wearing contact lenses until symptoms have settled and a clinician advises that they are safe to restart. Clean discharge gently with fresh cotton or a clean damp cloth each time.

A GP consultation can help distinguish conjunctivitis from corneal or eyelid problems. Take note of whether one or both eyes are affected, how symptoms began, and whether vision has changed.

Arrange prompt medical assessment for significant eye pain, reduced or blurred vision, marked light sensitivity, injury, swelling around the eye, or symptoms in a contact-lens wearer. Seek urgent help if the eye becomes very painful, vision suddenly changes, or you cannot open the eye. These features can indicate a problem deeper than simple conjunctivitis.

Could this be viral, bacterial, allergic or another eye problem? Do I need antibiotic treatment? When can I return to contact lenses, work or school? Which symptoms should prompt urgent review?
