In preseptal cellulitis testing, which examination is included?

• A. Lid eversion
• B. Audiometry
• C. Slit-lamp corneal staining
• D. Visual field testing

Answer: (A)

Evaluating suspected preseptal cellulitis hinges on a careful eyelid exam to identify the source and extent of infection. Lid eversion is essential because it lets you turn the eyelid inside out and directly inspect the palpebral conjunctiva and lid margin. This reveals signs of conjunctival involvement, discharge, foreign bodies, or a localized lid abscess that might accompany the eyelid infection, and it helps determine whether the infection is truly limited to preseptal tissues or if there’s a hidden complication. Other tests listed aren’t targeted to the eyelid infection: audiometry checks hearing, slit-lamp corneal staining focuses on the cornea rather than the lid, and visual field testing assesses the optic pathways. So lid eversion is the appropriate examination to include.
