Causes
Conjunctivitis can occur in people of all ages. However, infectious conjunctivitis is more common in children than in adults, as bacteria and viruses are easily spread from child to child once they play. Conjunctivitis also can accompany ear infections or sinusitis, thanks to a standard underlying cause.
Eye anatomy
Neonatal conjunctivitis (occurring during the primary three weeks of a baby’s life) are often caused by infection contracted during birth.
Non-infectious conjunctivitis is caused by allergens, chemical factors or environmental factors. the foremost frequent causes of allergic conjunctivitis are seasonal pollens, animal dander, and dust. Conjunctivitis occurring during pollen season is probably going to be a sort of pollinosis .
Environmental or chemical sorts of conjunctivitis are caused by irritating substances entering the eyes. Common irritants are household cleaners, sprays of any kind, smoke, foreign objects, smog, and industrial pollutants.
Persistent conjunctivitis are often related to an underlying disease like atrophic arthritis and systemic LE .
Symptoms and diagnosis
Diagnosis of conjunctivitis is formed by a doctor supported the signs and symptoms and an individual's recent health history. Laboratory tests are rarely necessary. Symptoms of conjunctivitis vary counting on the cause but typically include.
Infectious conjunctivitis
The symptoms of viral conjunctivitis are variable but usually feature an intensely red eye and excessive watery discharge that's not green or yellow. Viral cold-like symptoms, like nasal congestion and runny nose, can also be present. The eyelids could also be swollen and therefore the eyes sensitive to bright light.
Characteristic symptoms of bacterial conjunctivitis are thick purulent (mucus-like) discharge from the eyes, eyelids stuck together within the morning, and swelling of the eyelids . The discharge is typically thick and yellow or green in colour. The lymph nodes located ahead of the ears could also be enlarged.
Bacterial conjunctivitis usually occurs in both eyes while viral conjunctivitis is more likely to occur in only one eye.
Non-infectious conjunctivitis
The symptoms of allergic conjunctivitis are usually seasonal and include intense itching (made worse by rubbing the eyes) and tearing. Soreness is minimal or absent. These symptoms could also be amid other typical allergic symptoms, like sneezing, itchy nose, and/or a scratchy throat.
Pain, sensitivity to bright lights, watering, and blurred vision are typical symptoms of chemical or environmental conjunctivitis.
Conjunctivitis could also be confused with blepharitis, which is inflammation of the sides of the eyelids. Blepharitis may be a common eye disorder that affects people of all ages; the standard symptoms are red, itchy, irritated eyelids and dandruff-like scales on the eyelashes.

If you wear contact lenses and develop symptoms of conjunctivitis you ought to stop wearing your lenses and visit your doctor as soon as possible. Conjunctivitis requires prompt treatment if you're a contact wearer because it carries a better risk of keratitis (inflammation of the cornea)which can cause permanent damage to the eyes.

Infectious conjunctivitis
Viral conjunctivitis will usually disappear on its own (within two to four weeks) without use of anti-viral medication. Symptoms could also be relieved by the appliance of cold compresses and eye drop lubricants, like artificial tears. However, because viral conjunctivitis is very contagious for 2 weeks after symptoms first appear, as long because the eyes are red, it's important to require steps to stop its spread to people .
In cases of bacterial conjunctivitis, frequent use of a clean, warm washcloth to get rid of the discharge could also be required. Antibiotic eye-drops or ointment prescribed by a doctor are going to be needed to assist clear up the infection. Oral antibiotics could also be required for treatment of some infections. With treatment, bacterial conjunctivitis usually resolves within one to 2 weeks.
Non-infectious conjunctivitis
For treatment of allergic conjunctivitis, the allergen causing the conjunctivitis should be avoided. Use of eye make-up should even be avoided.
Allergic conjunctivitis are often treated by the appliance of cold, moist washcloths to the eyes and use of lubricating eye drops. Decongestant eye drops and topical antihistamines obtained from a pharmacy also will help to alleviate symptoms. Stronger medication, like topical corticosteroids, requires a prescription from your doctor.
Treatment of environmental or chemical conjunctivitis requires prompt and thorough flushing of the eyes with large amounts of water. A healthcare professional should be contacted if a chemical of any type splashes into the eyes. Many common household cleaning products are damaging to delicate eye tissue.
