Step 1 / 1 · Preseptal vs postseptal
Preseptal vs postseptal? (pain on eye movement/proptosis/ophthalmoplegia)
💡 Infection of postseptal soft tissue (muscle/fat) (vs preseptal = eyelid only); more common in children, 86–98% from sinusitis (ethmoid), also odontogenic/traumatic. Key distinguishing features: pain on eye movement + proptosis + ophthalmoplegia + chemosis ± reduced vision/RAPD + fever and raised WBC (eyelid swelling occurs in both and does not differentiate); bilateral → suspect cavernous sinus thrombosis. Complications: vision loss (~11%)/subperiosteal or orbital abscess/cavernous sinus thrombosis/meningitis/brain abscess.
