Distinguishing between Orbital and Preseptal Cellulitis

Some medical conditions have signs and symptoms that significantly overlap, making a diagnosis a little more difficult. Epididymitis, testicular torsion, and torsion of the testicular appendage are examples, but orbital and preseptal cellulitis are others that can cause significant diagnostic confusion.

Both conditions are more common in children than in adults, and preseptal or periorbital cellulitis is more common in children under 5. The preseptal and orbital spaces are separated by only a thin membranous septum that originates in the orbital periosteum and inserts into the tarsal plates. It is only this thin septum that stands as a barrier against progression of the preseptal infection…

EyeWiki

The diagnosis of orbital cellulitis is based on clinical examination. The presence of the following signs is suggestive of orbital involvement: proptosis, chemosis, pain with eye movements, ophthalmoplegia, optic nerve involvement as well as fever, leukocytosis (75% of cases), and lethargy.

American Academy of Ophthalmology

Ophthalmic signs most frequently seen with orbital cellulitis are limited ocular motility, proptosis, chemosis, and conjunctival hyperemia.

StatPearls

Orbital cellulitis is defined as a serious infection that involves the muscle and fat located within the orbit. It is also sometimes referred to as postseptal cellulitis. Orbital cellulitis does not involve the globe itself. Although orbital cellulitis can occur at any age, it is more common in the pediatric population.The causative organisms of orbital cellulitis are commonly bacterial but can also be polymicrobial, often including aerobic and anaerobic bacteria and even fungal or mycobacteria
