Pink eye, also known as conjunctivitis, is an inflammation of the conjunctiva, the thin, clear tissue that lines the inside of your eyelid and covers the white part of your eyeball. It is caused by an infection, allergies, or a foreign object in the eye. If left untreated, pink eye can cause serious complications, such as scarring of the cornea, vision loss, and even blindness. Fortunately, pink eye can be treated easily and effectively with the right medication and home remedies.
Causes of Pink Eye
Pink eye can be caused by a variety of factors, including: bacterial infections, such as staph or strep; viral infections, such as herpes simplex or adenovirus; allergies, such as dust or pollen; and foreign objects, such as dirt or dust. Other causes can include chlorine exposure, contact lenses, and extended use of eye makeup.
Signs and Symptoms of Pink Eye
The most common signs and symptoms of pink eye include: redness in the white of the eye or inner eyelid; increased amount of tears; discharge from the eye, which can be clear, yellowish, or greenish; itching or burning in the eye; and increased sensitivity to light. Other symptoms may include blurred vision, swelling of the eyelids, and a feeling of grittiness in the eyes.
Diagnosis of Pink Eye
If you suspect you have pink eye, it is important to see a doctor right away. Your doctor will perform a physical examination of the eyes, and may take a sample of the discharge from the eye to check for bacteria or viruses. Depending on the cause, your doctor may also order additional tests, such as an allergy test or a CT scan.
Treatment of Pink Eye
Treatment for pink eye depends on the cause. For bacterial infections, antibiotics may be prescribed, while viral infections typically require supportive care, such as lubricating eye drops. Allergic conjunctivitis can be treated with antihistamines or steroid drops. Other treatments may include warm compresses, artificial tears, and avoiding contact with irritants or allergens.
Prevention of Pink Eye
The best way to prevent pink eye is to practice good hygiene. Wash your hands often with soap and water and avoid touching your eyes. If you wear contact lenses, always wash your hands before touching them. Dispose of contact lenses as directed by your optometrist and avoid sharing towels, pillows, or makeup with others.
When To See a Doctor
If you experience any of the signs and symptoms of pink eye, it is important to seek medical attention right away. Your doctor will be able to determine the cause and provide the appropriate treatment. It is also important to see a doctor if your symptoms worsen or if you experience any pain or vision changes.
