Conjunctivitis is an inflammation of the conjunctiva – the membrane that lines the inner surface of the eyelids. It may be caused by a virus, bacteria, irritating substances, allergens, or sexually transmitted infections. Symptoms of conjunctivitis include redness in the white of the eye or inner eyelid, increased tearing, a thick yellow discharge or other discharge, itching eyes, burning eyes, blurred vision, and sensitivity to light. Treatment options include antibiotics or other medication, eye baths, warm/cool compresses (depending on cause), removing allergens from the environment, homoeopathy, boric acid eyewash, and herbal therapies.
