A 69-year-old woman developed acute angle-closure glaucoma 2 weeks after successful transvenous coil embolization of a traumatic carotid-cavernous sinus fistula. The angle-closure glaucoma was precipitated by oculomotor palsy caused by transvenous coil packing of the cavernous sinus. Emergency iridotomy resulted in normalization of the intraocular pressure and restoration of vision. ...

Sinus barotrauma, secondary to mucosal disturbances, is a common finding within the aviation community. Multiple etiologies have all led to mucosal inflammation and thickening with potential obstruction of the sinus osteomeatal complex, especially during the barometric changes of flight. Obstruction can, therefore, lead to problems with sinus pressure equilibration with ...
