A Case of Intraorbital Abscess in the Upper-lateral Part of the Orbit Following Acute Sinusitis

Abstract

Orbital infection mainly develops as a complication of sinusitis, and often disturbs the functions of the eye by raising orbital pressure due to abscess formation. We herein report on a case of an intraorbital abscess in the upper-lateral part of the orbit following acute sinusitis. At presentation, the sinusitis itself had already been improved and the abscess did not have contact with frontal or the ethmoid sinuses. A quick and correct diagnosis of sinusitis followed by orbital infection is essential. An urgent surgical drainage along with an adequate use of antibiotics is required to preserve the eyesight.
