Orbital Cellulitis
Nowhere is there a greater discrepancy... than in differentiating between periorbital and orbital cellulitis in children. The former tends to be overdiagnosed while the latter is often undertreated - William N Clarke MD

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…

The Hot Orbit: Orbital Cellulitis
Orbital cellulitis is an uncommon condition previously associated with severe complications. If untreated, orbital cellulitis can be potentially sight and life threatening. It can affect both adults and children but has a greater tendency to occur in the pediatric age group.
An eye for trouble: orbital cellulitis
Patients tend to present with a rapid development of symptoms. Periorbital cellulitis tends to present with swelling of eyelids and skin erythema or discoloration. Fever, conjunctival injection and associated discharge may be present; however, visual acuity, movements and pupillary response will be normal. Orbital cellulitis has similar, but more severe symptoms, often including proptosis, ocular pain, raised intraocular pressure, painful and restricted movements, and reduced or complete loss of trigeminal nerve sensation.
Emergency management: orbital cellulitis
The single most important imaging investigation in orbital cellulitis with suspected orbital abscess is a CT scan, as this would aid in the detection and demarcation of the abscess and assessment of the sinuses. However, this may not be possible in resource-poor environments. Ocular ultrasonography is also useful in cases of orbital abscess, and plain sinus X-rays may show air-fluid level in the sinuses.

If the infection moves past the septum, into the orbital fat or the extraocular muscles that move the eye, it becomes a medical emergency, an orbital cellulitis, also called a septal cellulitis.
Non-medial infectious orbital cellulitis: etiology, causative organisms, radiologic findings, management and complications
Orbital cellulitis is an ophthalmic emergency, which is associated with vision-threatening adverse effects. The purpose of this study is investigating etiology, radiologic findings, management and complications of patients with non-medial orbital cellulitis.
Paediatric periorbital cellulitis: A 10‐year retrospective case series review
Periorbital cellulitis is the umbrella term used to describe a group of conditions ranging from pre‐septal cellulitis to cavernous sinus thrombosis using the modified Chandler's classification. Pre‐septal cellulitis is the most common manifestation of periorbital cellulitis.
Periorbital and Orbital Cellulitis
Periorbital cellulitis often occurs from a scratch or insect bite around the eye that leads to infection of the skin. Symptoms can include swelling, redness, pain, and tenderness to touch occurring around one eye only. The affected person is able to move the eye in all directions without pain, but there can be difficulty opening the eyelid, often due to swelling. Vision is normal.
Periorbital and orbital cellulitis in children
Nowhere is there a greater discrepancy between paediatricians and ophthalmologists than in differentiating between periorbital and orbital cellulitis in children. The former tends to be overdiagnosed while the latter is often undertreated.
Preseptal vs Orbital Cellulitis
Differentiating orbital from preseptal cellulitis is extraordinarily important given that orbital cellulitis has the potential to cause a compartment syndrome within the eye socket resulting in irreversible vision loss to the affected eye.

Epididymitis, testicular torsion, and torsion of the testicular appendage are examples, but orbital and preseptal cellulitis are others that can cause significant diagnostic confusion.

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
