1.1. Preseptal cellulitisPreseptal cellulitis ::– inflammation – inflammation involves structures anterior to the involves structures anterior to the orbital septum.orbital septum.
2. 2. Orbital cellulitis:Orbital cellulitis: the inflammation the inflammation is behind the orbital septum which is behind the orbital septum which may or may not spill over the lidsmay or may not spill over the lids
Preseptal cellulitisPreseptal cellulitisSymptoms & signs:Symptoms & signs: Swelling, erythema, Swelling, erythema,
chemosis of lids chemosis of lids Conjuntival discharge Conjuntival discharge No proptosis, ocular No proptosis, ocular
movements movements Vision not affected Vision not affected
Treatment:Treatment: Antibiotics, NSAIDAntibiotics, NSAID
Orbital cellulitisOrbital cellulitisDef: Purulent inflammation of the cellular tissue
of the orbit.
Cause:
-Spread of inflammation from neighboring parts – nasal sinuses, Dacryocystitis, dental infection, deep injuries, retained foreign body,
-septic operations, DCR, RD, SQUINT
-posterior extension of suppurative infection of eye lid, panophthalmitis, facial erysipelas,
- Metastases in pyaemia
