Q1 · Orbital Cellulitis
NEET PGHardWhich feature distinguishes orbital (post-septal) cellulitis from preseptal cellulitis and marks it as a sight- and life-threatening emergency?
Explanation
Orbital cellulitis involves structures behind the orbital septum, causing proptosis, painful and restricted eye movements, and reduced vision — features absent in preseptal cellulitis. It is an emergency requiring IV antibiotics and imaging, as it can spread intracranially.
