By Dr. Navaneeth K. Unni•Published on 2027-10-15•Patient Group: Adults
Clinical Overview & Pathophysiology
Conjunctivitis, commonly known as pink eye, is an inflammation of the clear membrane lining the eyelid and eyeball. If the conjunctivitis is infectious (viral or bacterial), it is highly contagious from the onset of symptoms for 7 to 14 days, until active tearing and discharge clear.
Key Clinical Facts & Indicators
- Infectious Conjunctival Flushing: Sclera (white of the eye) appearing bright pink or red, with swelling.
- Discoloration of Discharge: Watery discharge (viral) or thick yellow-green discharge (bacterial) that crusts eyelashes.
- Pruritus & Grit Sensation: Constant itching, burning, and feeling like sand is trapped in the eye.
- High Transmission Risk: Easy spread to family members through shared towels, sheets, or touching door handles.
Lifestyle & Nutritional Guidelines
Practice strict hand hygiene; wash hands frequently. Avoid touching or rubbing the eyes. Use separate towels and pillowcases daily. Discard old eye makeup. Wash eyes with cool water. Keep home spaces ventilated. Follow an individualized care plan.
Frequently Asked Questions
Q: How does pink eye spread?It spreads through direct contact with discharge from the infected eye, or by touching surfaces contaminated with the virus or bacteria.
Q: When is it safe to return to school or work?It is generally safe to return once the eye redness is resolving and there is no active watery or yellow discharge.
