What is conjunctivitis (red eye)? Conjunctivitis, commonly known as red eye, is the inflammation of the conjunctiva, the clear tissue covering the white part of the eye and lining the inner surface of the eyelids. It can cause redness, itching, discharge, and discomfort.
What causes conjunctivitis? Conjunctivitis can be caused by various factors, including viral infections (e.g., adenoviruses), bacterial infections (e.g., Staphylococcus or Streptococcus), allergies, irritants (e.g., smoke, chemicals), and contact lens-related issues.
Is conjunctivitis contagious? Yes, conjunctivitis can be contagious, especially if it is caused by a virus or bacteria. It is important to practice good hygiene, avoid touching the eyes, and wash hands frequently to prevent spreading the infection.
What are the symptoms of conjunctivitis? Symptoms may include redness, itching, watering or discharge from the eye, sensitivity to light (photophobia), a gritty feeling in the eye, and blurred vision.
How is conjunctivitis diagnosed? A healthcare provider can diagnose conjunctivitis through a physical examination of the eye and a discussion of symptoms. In some cases, they may take a sample of eye discharge for laboratory testing.
How is conjunctivitis treated? Treatment depends on the cause of conjunctivitis. Bacterial conjunctivitis may be treated with antibiotic eye drops or ointments. Viral conjunctivitis usually resolves on its own and may be managed with supportive care (e.g., warm compresses, artificial tears). Allergic conjunctivitis can be managed with antihistamine eye drops or oral medications.
Can I wear contact lenses if I have conjunctivitis? It's generally recommended to avoid wearing contact lenses while you have conjunctivitis, as they can exacerbate the irritation and may increase the risk of spreading the infection. Consult your eye doctor for specific guidance.
When should I see a doctor for conjunctivitis? You should see a doctor if you experience severe eye pain, vision changes, or if your symptoms worsen despite home care. Additionally, if you suspect a bacterial or viral infection, seeking medical attention is important.
How can I prevent conjunctivitis? To prevent conjunctivitis, practice good hygiene, avoid touching your eyes with dirty hands, wash your hands frequently, and avoid sharing personal items like towels and eye makeup.
Can conjunctivitis lead to serious complications? While conjunctivitis is typically a mild and self-limiting condition, complications can rarely occur. These may include corneal inflammation (keratitis), more severe eye infections, or the spread of infection to other parts of the body.
Remember, this information is for general guidance only. If you have specific concerns or symptoms related to conjunctivitis, it's best to consult a healthcare professional or eye specialist for accurate diagnosis and appropriate treatment.
