Orbital cellulitis is a severe bacterial infection that affects the tissues surrounding the eye, resulting in inflammation and oedema. It usually affects the soft tissues of the eye socket, which include the muscles and fat behind the eye. People of all ages can suffer from this disorder, although it typically affects youngsters. It is a common complication of sinus infections, especially when the sinuses around the eye, such as the ethmoid sinuses, get infected and disseminate bacteria into the orbit (eye socket). Symptoms Symptoms of orbital cellulitis can range from moderate to severe, including eye pain. The patient is experiencing redness and swelling of the eyelids. Symptoms may include difficulty moving the eye, poor vision, fever, and exophthalmos (eye protrusion). Causes and Risk Factors Bacterial infection is the leading cause of orbital cellulitis, with common bacteria such as Streptococcus pneumoniae, Staphylococcus aureus, and Haemophilus influenzae. Untreated sinus infections, face traumas, or eye-related procedures can all cause the illness. Individuals with compromised immune systems are also at increased risk. Treatment Orbital cellulitis demands immediate medical care. We often administer antibiotics intravenously (IV) to combat the illness. In severe situations, surgery may be required to empty the abscesses. Early detection and treatment are crucial in avoiding problems such as irreversible eyesightloss or infection spreading to the brain.
