Eye infections in children


Severe bacterial infections of the eye causing swelling and redness of the eyelid, the skin around the eyes (periorbital cellulitis) and areas within the eye socket (orbital cellulitis). The area around the eyes can be infected through wounds, insect bites, or sinus infections (sinusitis). Infection can also reach the eye from other parts of the body's blood supply. Simple eye infections, such as conjunctivitis, or are caused by bacteria or viruses. Reddened eyes can also be a sign of allergies. Simple eye infections and allergic problems are far more common than severe infections type of orbital and periorbital cellulitis.



Symptoms The first symptom of severe eye infections are usually swollen, red eyelids. In more than 90% of children who have an eye infection affected only one eye. Most children have a fever, about 20% have a runny nose and about 20% had conjunctivitis. When it comes to orbital cellulitis, around the bulging which paralyzes the muscles of the eye and the eye can not move. Eye pain and vision is damaged. Especially with periorbital cellulitis, but with orbital cellulitis, eyelid can be so bloated that the ophthalmologist should open about a special instrument. Orbital cellulitis can lead to the formation of a clot in an artery or vein that supply the retina. This blockage of blood flow damages the retina and can cause blindness. Sometimes the infection spreads from the eye socket to the brain, causing an abscess, or the lining of the brain, causing bacterial meningitis. Clots can clog veins that drain blood from the brain, causing headaches, loss of consciousness and even death. Periorbital cellulitis may be associated with infection, blood flow, but generally does not spread to the eye socket (orbit) and the brain. Diagnosis and Treatment Doctor examines an eye on the signs of the infection and whether there has been around a swivel, is bulging and whether the vision deteriorated. The blood sample can help identify the causative bacteria. CT helps to locate the infection and determine how far it has spread. Children with severe eye infections are hospitalized immediately and treated with intravenous antibiotics. Periorbital celuhtis be treated with antibiotics for 10-14 days (first intravenously and later possibly the mouth). Orbital cellulitis requiring surgical drainage, as well as 2-3 weeks of IV antibiotics (usually intravenously). Some cases are mild periorbital cellulitis can favorably respond to antibiotics taken by mouth. milder but more common eye infections (conjunctivitis) can be treated with any antibiotic drops or ointments or antibiotics by mouth in 7-10 days, assuming a cause of bacteria, not viruses .
