Published on: January 17, 2018
Background:
Although vision-threatening sinusitis complications are not uncommon, an unusual case of asymptomatic posterior orbital cellulitis resulting from maxillary and ethmoidal sinus infection is presented.
Methods, Results:
An 11-year-old girl was brought to us for a routine optometric examination, reporting only blurred distance vision. A mild afferent pupillary defect was the key to detection and diagnosis of a vision-threatening posterior orbital cellulitis.
Conclusions:
A literature review of relevant anatomic and pathologic mechanisms, as well as radiologic recommendations, follows. This case appears to be a new clinical entity, an asymptomatic variant of posterior orbital cellulitis.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
