==Physical Examination==
Patients with orbital cellulitis usually appear ill. Physical examination of patients with orbital cellulitis is usually remarkable for [[fever]], [[proptosis]], [[ophthalmoplegia]], and impaired [[visual acuity]].The physical examination should assess:<ref name=Eyewikiorbitalcellulitis>American Academy of Ophthalmology EyeWiki (2015)http://eyewiki.aao.org/Orbital_Cellulitis</ref>
*[[Vital signs]]
*[[visual acuity|Best-corrected visual acuity]](BCVA)
*Color vision assessment
*[[Proptosis]] measurements using Hertel exophthalmometry
*[[Visual field]] assessment
*Assessment of [[pupillary]] function with particular attention paid to the presence of a relative afferent [[pupillary]] defect (rAPD)
*[[Eye movement|Ocular motility]] and presence of pain with eye movements; additionally, there may be involvement of the [[Oculomotor nerve|III]], [[Trochlear nerve|IV]], and [[Abducent nerve|VI]] [[cranial nerves]] in cases of [[cavernous sinus]] involvement.
*[[Orbit]] exam should include documentation of direction of displacement of the globe
*Measurement of [[intraocular pressure]] (IOP)
*[[Slit lamp]] test in cases of severe [[proptosis]]
*[[Dilated fundus exam]] to exclude optic [[neuropathy]] or retinal vascular occlusion
*Nasal [[sinus]] examination
*[[Otoscopy]] for presence of [[otitis media]]
*Oral examination for [[oropharyngeal]] [[infection]] and [[dentition]]
