Conjunctivitis
Overview:
Conjunctivitis is the inflammation of the delicate skin which covers the white of the eye underneath the eyelids (the medical term for this is the conjunctiva or the conjunctival membrane).
Signs and Symptoms:
Some or all of the following symptoms may be present:
* A gritty feeling in the eyes, just under the eyelids
* Burning, itchy eyes that discharge heavy, sticky pus - eyelids may stick together upon waking in the morning as mucus has dried on the eyelashes and lids overnight
* Excess tear production
* Swollen lymph nodes
* Redness
Causes and Organs Affected:
The most common cause of conjunctivitis is irritation to the eye from allergens such as dust mites, moulds, animal fur and chemicals such as pool chlorine. The eyes become irritated, causing the sufferer to rub the eyes, making them even more irritated!
Young children or babies may suffer from conjunctivitis following a cold or sore throat. Additionally, conjunctivitis commonly occurs in babies if the tear ducts are not fully developed or if the baby's eyes are exposed to bacteria during the birthing process.
Risk Factor:
Risk factors for pink eye include:
* Exposure to an allergen for allergic conjunctivitis
* Exposure to someone infected with the viral or bacterial form of conjunctivitis
Both viral and bacterial conjunctivitis are common among children and are very contagious. Someone with conjunctivitis may be contagious for seven to 14 days after signs and symptoms first appear.
People who wear contact lenses, especially extended-wear lenses, may be more prone to conjunctivitis.
Treatment:
Bacterial and viral conjunctivitis are highly contagious. Unless you take preventive measures, the condition may spread to your other eye or to other people.
Practice good hygiene by washing your hands often and well, and keeping them away from the infected eye.
Avoid sharing bedding, towels, face washers or handkerchiefs with other family members.
Children with infectious conjunctivitis should be kept home from school.
Always use eye protection when cycling, swimming, or using industrial materials such as chemicals or powdered cement.
Keep your home clean and well-ventilated to reduce the build-up of dust mites and mould.
Other Information:
An eyewash using chamomile, or fennel tea bag may be effective in relieving conjunctivitis symptoms - pour boiling water over the herbs and allow to steep for 20 minutes before removing tea bag; dip cotton balls in the cooled liquid and use them to soothe and wash the eyes. Use the eyewash 2-3 times per day, making a fresh batch each time to avoid contamination.
If dust or irritants have caused the problem, flushing the eyes with fresh cool water to remove them will help.
