Acute visual loss may occur in association with sinusitis either as a complication of orbital cellulitis or, less frequently, as a part of the orbital apex syndrome. We describe two cases of temporary monocular visual loss caused by sinusitis. In one case the visual loss was due to orbital cellulitis; while in the other patient it was due to incompletely developed orbital apex syndrome. This la...

Transient monocular visual loss patterns and associated vascular abnormalities.

To determine if certain transient monocular visual loss patterns predict the associated vascular abnormalities, we prospectively evaluated 100 consecutive patients. Each patient had hematologic tests, a carotid artery study (arteriography in 74, duplex ultrasonography in the remaining 26), and an ophthalmologic examination. Patients with altitudinal or lateralized transient monocular visual los...

We measured binocular gaze using the magnetic search coil technique during attempted fixation (mo...
