Acute visual loss in association with sinusitis

Abstract

Acute visual loss may occur m association with sinusitis either as a comphcation of orbital cellulitis or, less frequently, as a part of the orbital apex syndrome. We describe two Casey of temporary monocular wsual loss caused by sinusitis. In one case the visual loss was due to orbital cellulitis; while in the other patient It u as due to incompletely developed orbital apex syndrome. This later mode of presentation is called ‘pamal orbltal apex syndrome’ by some authors and ‘posterior orbital cellulitis’ by others.
