Description |
| |
Conjunctivitis is an irritation or infection of the eye caused by bacteria, viruses, chemicals or allergies. Symptoms include a scratchy feeling in one or both eyes and redness in the whites of the eyes. A discharge may be present, causing the eyelids to stick together in the morning. Sensitivity to light is another common symptom. Diagnosis of the source of infection or irritation can be made by examining a smear of the discharge from the eye under a microscope or by culturing the virus or bacteria. This is often not done and so usually the cause is unknown. Viral and bacterial conjunctivitis can be spread by direct contact with secretions from the eye. This type of infection may also be spread indirectly through towels, washcloths, handkerchiefs and other objects that have been contaminated with eye secretions. |
