Periorbital cellulitis is a very common disease in pediatric population, it describes an infection involving the adjacent soft tissues anterior to the orbital septum. Pathogens involved are generally Gram-positive cocci after introduction of Haemophilus influenzae vaccine. We report a case of Neisseria gonorrhoeae periorbital cellulitis associated with bacterial conjunctivitis in a child. There are few cases reported in the literature with this microorganism as the causal agent. With this case, we would like to emphasize the importance to do a culture of the ocular secretion if it exists because this allowed us to determine an infrequent agent of this disease. Existen pocos casos descritos en la literatura en los que este microorganismo aparece como agente causal de celulitis periorbitaria.

It comprises of three main clinical entities with the most important distinction between that of orbital and periorbital cellulitis:. Orbital infections represent more than half of primary orbital disease processes 2. These infections typically present in children and young adults but can affect any age group. Periorbital cellulitis often results from contiguous spread of an infection of the face, teeth, or ocular adnexa.
CT is the imaging investigation of choice as it is:. Diffuse soft-tissue thickening and areas of enhancement anterior to the orbital septum are seen in periorbital cellulitis. It is very difficult to differentiate between preseptal edema and periorbital cellulitis on CT 4. Rarely performed, as not usually necessary. Like CT, it will identify a subperiosteal abscess as:. MRI may occasionally have a role in diagnosing endophthalmitis since the presentation can often be non-specific. Key findings include :.
Periorbital cellulitis is treated with oral antibiotics. Orbital cellulitis is treated with intravenous antibiotics. However, if a subperiosteal abscess is present, surgical drainage may be necessary 1.

Preseptal and Orbital Cellulitis
[Neisseria Gonorrhoeae: An Infrequent Causal Agent of Periorbital Cellulitis in a Child]
Preseptal cellulitis periorbital cellulitis is infection of the eyelid and surrounding skin anterior to the orbital septum. Orbital cellulitis is infection of the orbital tissues posterior to the orbital septum. Either can be caused by an external focus of infection eg, a wound , infection that extends from the nasal sinuses or teeth, or metastatic spread from infection elsewhere. Symptoms include eyelid pain, discoloration, and swelling; orbital cellulitis also causes fever, malaise, proptosis, impaired ocular movement, and impaired vision. Treatment is with antibiotics and sometimes surgical drainage. Preseptal cellulitis and orbital cellulitis are distinct diseases that share a few clinical symptoms and signs.
