What this deck covers
Periorbital & Orbital Cellulitis in ten clinical teaching cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong.
Diagnoses and management options tested
Across the ten cases you are asked to choose between options such as: Unilateral eyelid erythema, Fever and elevated temperature, Sudden onset of symptoms, Frontal sinus, Ethmoid sinus, Maxillary sinus, Sphenoid sinus, Chemosis and fever, Unilateral eyelid erythema and edema, Mild conjunctival swelling alone, Staphylococcus aureus, Haemophilus influenzae type B, Streptococcus pneumoniae, Neisseria meningitidis, Routinely for all cases to confirm diagnosis, Severe periorbital cellulitis requiring hospitalization, Amoxicillin alone, Cefalexin or Cefuroxime, Penicillin V, Cavernous sinus thrombosis and intracranial extension, Subperiosteal abscess formation, Permanent vision loss or blindness, Acute angle-closure glaucoma, Outpatient oral antibiotics with close follow-up, Empiric intravenous antibiotics and hospitalization, Symptoms may persist for months despite antibiotics.
Clinical pearls from this deck
- The bedside line between the two is the orbital septum. Preseptal (periorbital) disease spares the globe, extraocular muscles, and optic nerve — so normal vision and full, painless eye movements are the reassuring hallmark. Eyelid erythema, fever, and sudden onset happen in both and don’t localize.
- The ethmoid air cells sit right against the medial orbit, separated only by the paper-thin lamina papyracea — easily breached, so ethmoid sinusitis is the classic source. The valveless orbital/facial veins also allow retrograde spread, raising the risk of posterior extension and cavernous sinus thrombosis.
The ten worked cases in this deck, with the images and the full explanation of every option, are part of Pediatric Case Review membership. See what is included.
