==Overview==
Common causes of orbital cellulitis are infections with either ''[[Staphylococcus aureus]]'', ''[[Streptococcus pneumoniae]]'', ''[[Haemophilus influenzae]]'', or ''beta-hemolytic streptococci''.
Orbital cellulitis occurs most commonly from typical [[bacterial infections]]. In some cases, [[Mycobacterium|mycobacteria]] or [[Mycosis|mycosis]] may also be implicated. The most common underlying condition is [[Sinusitis|ethmoid sinusitis]], which has been reported in 90-98% of orbital cellulitis cases. The most commonly reported [[Pathogen|pathogens]] are [[Staphylococcus aureus|''Staphylococcus aureus'']], [[Streptococcus|''Streptococcus spp.'']], and [[Haemophilus influenzae|''Haemophilus influenzae'']]. With the rise of [[Antibiotic resistance|microbial resistance]], [[Methicillin-resistant staphylococcus aureus|methicillian-resistant ''Staphylococcus aureus'' (MRSA)]] must be considered as a potential cause and correlated with geographic [[prevalence]]. Though some causes may be uncommon, orbital cellulitis is a medical emergency and all [[etiologies]] must be considered.<ref name="pmid15318671">{{cite journal| author=Hasanee K, Sharma S| title=Ophthaproblem.

Blood cultures are typically positive in 4% of patients with orbital cellulitis with the highest reported rate of positive result of 31%. Mucosal swabs of nasal and preseptal mucosa show a slightly higher positive culture result of 51%; however, their accuracy is a topic of debate considering the normal flora in these tissues. The most likely source of a positive culture in confirmed orbital cellulitis patients is a surgical specimen from an abscess or nasal sinus aspirate.

===Cause by Pathogen===
The most commonly reported pathogens, regardless of culturing method were "Staphylococcus aureus", "Streptococcus spp.", and "Haemophilus influenza". With the rise of microbial resistance in more recent years, Methicillian-Resistant Staphylococcus Aureus (MRSA) must be considered as a potential cause and correlated with geographic prevalence. MRSA has been cultured in as high as 73% of cases in a retrospective study of orbital cellulitis patients. Alternatively, with the dissemination of *Haemophilus influenza type b (Hib)* vaccine, the incidence of *Haemophilus spp.* caused orbital cellulitis has decreased significantly.<ref name="pmid2214559">{{cite journal| author=Kamilov KhKh, Artemova EP| title=[Activation of immunity in patients with recurrent goiter]. | journal=Khirurgiia (Mosk) | year= 1990 | volume= | issue= 6 | pages= 112-5 | pmid=2214559 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=2214559 }} </ref><ref name="pmid22224014">{{cite journal| author=Lam Choi VB, Yuen HK, Biswas J, Yanoff M| title=Update in pathological diagnosis of orbital infections and inflammations. | journal=Middle East Afr J Ophthalmol | year= 2011 | volume= 18 | issue= 4 | pages= 268-76 | pmid=22224014 | doi=10.4103/0974-9233.90127 | pmc=3249811 | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=22224014  }} </ref><br>

It is important to note that, although rare, in immunocompromised patients we begin to see an increase in incidence of fungal and mycobacterial sources of infections.

Other ways in which orbital cellulitis may occur is from infection in the blood stream and from an eyelid skin infection. Upper respiratory infection, sinusitis, trauma to the eye, ocular or periocular infection and systemic infection all increase one’s risk of orbital cellulitis. [[Staphylococcus aureus]], [[Streptococcus pneumoniae]] and beta-hemolytic streptococci are three bacteria that can be responsible for orbital cellulitis.

Overview

Orbital cellulitis occurs most commonly from typical bacterial infections. In some cases, mycobacteria or mycosis may also be implicated. The most common underlying condition is ethmoid sinusitis, which has been reported in 90-98% of orbital cellulitis cases. The most commonly reported pathogens are Staphylococcus aureus, Streptococcus spp., and Haemophilus influenzae. With the rise of microbial resistance, methicillian-resistant Staphylococcus aureus (MRSA) must be considered as a potential cause and correlated with geographic prevalence. Though some causes may be uncommon, orbital cellulitis is a medical emergency and all etiologies must be considered.[1][2][3][4][5][6]

Causes

Orbital cellulitis occurs most commonly from bacterial infection. In some cases, mycobacterial or fungal infections are observed.[1][2][3][4] Difficulty arises in identifying a specific organism due to challenges in culturing the retroseptal orbital region.[7]

Cause by Pathogen

Common bacterial causes of orbital cellulitis include:[1][2][3]

In immunocompromised patients, additional causes may include:[2]

Cause by Etiology

Based on etiology, the most common underlying condition causing orbital cellulitis is ethmoid sinusitis, which occurs in 90-98% of cases.[1][5][6] Additional causes based on etiology include:[2][7]
