Bacterial conjunctivitis and viral conjunctivitis

Bacterial conjunctivitis and viral conjunctivitis are mainly distinguished by infectious microorganisms, clinical manifestations, course, and prognosis.

1. Bacterial

conjunctivitis is caused by bacterial infection, while viral conjunctivitis is caused by viral infection.

2. Clinical manifestations

Bacterial conjunctivitis secretions are usually mucopurulent, while viral conjunctivitis is characterized by light phobia, tears, and secretions similar to water and serous fluid.

3.

The course of bacterial conjunctivitis is relatively short and can be rapidly improved after appropriate antibiotic treatment. In contrast, viral conjunctivitis has a longer course and a longer duration, and drug treatment may not be effective.

4. Prognosis

Bacterial conjunctivitis is usually eliminated faster after timely treatment, with less damage to the eye. Viral conjunctivitis may sometimes lead to serious complications due to its long course, severe inflammation, and poor prognosis.
