Definition
Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the conjunctiva, which is the thin layer of tissue that covers the white part of the eye and lines the inner surface of the eyelids.
Causes
Pink eye can be caused by various factors including:
- Bacterial or viral infection
- Allergic reactions
- Chemical exposure
- Irritants like smoke or dust
- Foreign bodies in the eye
- Certain underlying health conditions
Symptoms
The common symptoms of conjunctivitis include:
- Redness in the white part of the eye or inner eyelid
- Watery or thick discharge from the eye
- Itchy or gritty sensation in the eye
- Increased sensitivity to light
- Blurred vision
Treatment
The treatment for conjunctivitis varies based on the cause:
- Bacterial conjunctivitis: Antibiotic eye drops or ointments may be prescribed.
- Viral conjunctivitis: Usually clears on its own without treatment, but antiviral medications may be prescribed in severe cases.
- Allergic conjunctivitis: Antihistamine eye drops or oral medications can help alleviate symptoms.
- Irritant-induced conjunctivitis: Flushing the eye with clean water and avoiding the irritant can provide relief.
It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
