What is periorbital cellulitis?

Periorbital cellulitis is indeed characterized as a common infection that affects the eyelid and the surrounding skin. This condition usually occurs when bacteria enter the skin through a break or cut, leading to redness, swelling, and warmth in the affected area. It is important to differentiate periorbital cellulitis from more serious conditions, such as orbital cellulitis, which involves the eye socket and can lead to complications. Understanding this distinction is crucial in terms of treatment and urgency, as periorbital cellulitis can often be treated effectively with antibiotics, while orbital cellulitis may require more immediate medical attention.

The other options describe different conditions: inflammation of the retina pertains to retinal issues, a growth on the conjunctiva refers to lesions or growths on the eye's surface, and refractive errors involve problems with how the eye focuses light. Each of these conditions is unrelated to the infection of the eyelid and surrounding skin, further solidifying that option B accurately captures the essence of periorbital cellulitis.
