ABSTRACT
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.

The purpose of our study was to investigate the diagnostic efficacy of two selected methods of in vitro allergy testing. Specifically, the PRIST/modified RAST I125 isotope systems and the Quantizyme/modified EAST alkaline phosphatase method were compared. The time, expense, convenience, and diagnostic efficacy of the two procedures are discussed. Special attention is given to the practicality of each method for the practicing physician.
