Conjunctivitis is an eye condition that may also be referred to as pink eye. It is an infection of the conjunctiva, which is the clear membrane that covers the eyelid and partially covers the eyeball. Conjunctivitis is often caused by a bacterial or viral infection; however, it may also be caused by an allergic reaction to some substance. A physician can help determine the cause of the infection and prescribe proper treatment.
Viral Conjunctivitis
Viral conjunctivitis cannot be cured since viruses do not respond to antibiotics. Symptoms may be at their worst for about three to five days, after which symptoms should begin to gradually improve. Most viruses clear up completely within three weeks.
Bacterial Conjunctivitis
Bacterial conjunctivitis should be treated with antibiotic eyedrops or antibiotic ointment. The antibiotic medications should begin to alleviate symptoms within one or two days. The medication should be used completely to prevent the bacterial infection from coming back. Bacterial eye infections may treated with a medication such as sulfacetamide and prednisolone drops. Side effects associated with this medication include stinging, burning, itching, redness, irritation, blurry vision, swelling of the eyelid and light sensitivity.
Allergic Conjunctivitis
Allergic conjunctivitis needs to be treated with eyedrops as well. Typically, the eyedrops used are some type of antihistamine, steroid, decongestant and anti-inflammatory medication. The drops should be used as prescribed to clear up the problem.
Other Treatments
Applying a warn compress to the eye may help relieve some of the discomfort associated with conjunctivitis. In the case of allergic conjunctivitis, a cool compress may feel better. Also, individuals who have frequent episodes of allergic conjunctivitis may want to purchase over-the-counter antihistamine drops such as Opcon-A or Naphcon-A.
Causes
Viral and bacterial conjunctivitis can be caused with various viruses and bacterias, but are usually caused by viruses or bacteria that cause colds. Conjunctivitis may occur along with a cold or soon after a cold.
Allergic conjunctivitis is usually caused by a pollen or some other airborne allergen that can irritate the surface of the eye. When the body attempts to attack the allergen, it can result in conjunctivitis.
Conjunctivitis may also occur in response to a chemical getting into the eye. Also, babies may develop conjunctivitis if they have a blocked tear duct.
