Infection limited to the tissues in the anterior part of the orbital septum and to the palpebrae was defined as preseptal cellulitis, whereas infections behind the orbital septum were considered orbital cellulitis
. The study was approved by Istanbul University, Cerrahpasa Medical Faculty Local Ethics Committee (Project number: 162181).
Retrobulbar optic neuritis presents with subacute loss of vision and pain on eye movement with normal appearing optic nerves initially.11 A few cases of stye, infected chalazion, pterygium and orbital cellulitis
were also reported, which present with headache as an associated symptom.
The differential diagnosis of idiopathic OM includes the following: infections (viral infections, orbital cellulitis
, orbital abscess, Lyme disease, Herpes zoster, and syphilis), inflammatory reaction (trauma, foreign body, bisphosphonaterelated reaction, and postvaccinal reaction), Tolosa-Hunt syndrome, thyroid ophthalmopathy, vasculitis (Wegener's granulomatosis, polyarteritis nodosa, rheumatoid arteritis, giant cell arteritis, and Kawasaki disease), systemic lupus erythematosus, sarcoidosis, inflammatory bowel disease, neoplasm, arteriovenous fistulas, and malformations (3).

Considerable controversy exists over the need for prophylactic antibiotics after midface fractures to prevent orbital cellulitis
. Courtney et al conducted a survey of British oral and maxillofacial surgeons to determine their practice habits when treating patients with orbital blowout fractures; they found that 47% of the respondents reported prescribing prophylactic antibiotics at the time of injury.
or abscess may lead to thrombosis of the superior ophthalmic vein, which may lead to cavernous sinus thrombosis.
This maybe difficult to distinguish clinically from orbital cellulitis
. Enhancing depth imaging optical coherence tomography can be useful in quantifying the increase in choroidal thickness, which can improve after systemic chemotherapy .
The peripheral 7th nerve weakness with early ecchymosis and necrosis of ocular adenexae distinguish this disease from other causes of orbital Cellulitis
and orbital apex syndrome.1 Central retinal artery occlusion can cause sudden-onset of blindness in rhino-orbito-cerebral mucormycosis.1
The differential diagnoses for periorbital swelling include orbital cellulitis
or abscess from an inflammatory or infectious disease process, trauma, orbital cyst, hypovitaminosis A with squamous metaplasia that involved the infraorbital sinus, and infiltrative or primary neoplasia.
with abscess formation following surgical treatment of canaliculitis.
Patient was started empirically on vancomycin, ceftazidime and metronidazole for orbital cellulitis
. He was also started on intravenous dexamethasone for painful left eye blindness.
