Which of the following signs is NOT typically associated with preseptal cellulitis?

Explanation:
Preseptal cellulitis involves tissue anterior to the orbital septum, so the orbit itself and its contents aren’t affected. That’s why vision is usually preserved. The typical signs are local eyelid inflammation—warmth, redness, and swelling—and ptosis can occur from eyelid edema. A decrease in visual acuity would point away from preseptal cellulitis and toward involvement of the globe or optic nerve, i.e., orbital cellulitis or another complication. So the sign not typically seen is reduced vision, while eyelid warmth, eyelid erythema, and ptosis fit with preseptal involvement.
