WHAT CAUSESING CONJUNCTIVITIS
Conjunctivitis, commonly known as pink eye, is the inflammation of the conjunctiva, which is the thin, transparent layer that covers the white part of the eye and lines the inner surface of the eyelids. There are several potential causes of conjunctivitis, including:
Viral Infections
Viruses, such as adenoviruses and herpes simplex virus, are a common cause of viral conjunctivitis. It is highly contagious and often spreads through coughing, sneezing, or touching infected surfaces and then touching the eyes.
Bacterial Infections
Bacterial conjunctivitis is caused by bacteria like Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. It can result from contaminated hands or objects coming into contact with the eyes.
Allergic Reactions
Allergic conjunctivitis is triggered by allergens like pollen, dust mites, pet dander, and certain medications. It typically affects both eyes and is more common in individuals with a history of allergies or asthma.
Irritants
Exposure to irritants such as smoke, fumes, chlorine in swimming pools, and certain chemicals can lead to irritant conjunctivitis.
Contact Lenses
Incorrect or improper use of contact lenses, such as wearing them for too long or not cleaning them properly, can cause conjunctivitis.
Foreign Bodies
When a foreign object, like dust, dirt, or an eyelash, gets trapped in the eye, it can cause irritation and inflammation.
Newborns
Newborn babies can develop conjunctivitis due to an infection during delivery, known as neonatal conjunctivitis.
Sexually Transmitted Infections (STIs)
Certain STIs, like chlamydia and gonorrhea, can cause conjunctivitis when the infection spreads to the eyes.
The symptoms of conjunctivitis may include redness, itching, burning sensation, excessive tearing, discharge (clear, white, yellow, or green), and sensitivity to light. The treatment of conjunctivitis depends on the underlying cause. While viral conjunctivitis often resolves on its own, bacterial conjunctivitis may require antibiotic eye drops or ointments. Allergic conjunctivitis can be managed by avoiding allergens and using antihistamine eye drops. If you suspect you have conjunctivitis, it’s essential to consult an eye care professional for proper diagnosis and treatment.
