Which finding is associated with both orbital and preseptal cellulitis?

• A. Optic nerve compression
• B. Proptosis
• C. Fever
• D. Eyelid edema

Answer: (D)

Eyelid edema is the finding that can appear in both conditions because both involve infection and inflammation of the eyelid tissues, leading to swelling. In preseptal (periorbital) cellulitis, the infection is anterior to the orbital septum, so swelling is confined to the eyelids but still present. In orbital cellulitis, there’s deeper orbital involvement, but swollen eyelids are still common due to the overall inflammatory process affecting surrounding tissues. By contrast, proptosis reflects forward displacement of the globe from orbital contents swelling and is more specific to orbital involvement; optic nerve compression implies deeper, posterior involvement with potential vision changes; fever is a general sign of infection that isn’t as specific to where the infection sits. So eyelid edema best fits as the finding associated with both conditions.
