Abstract:
Recently, endoscopic sinus surgery (ESS) has been acknowledged as a standard surgical procedure for the treatment of chronic rhinosinusitis. Orbital complications of varying degrees that may occur during ESS have been widely reported. Blindness, one of the major complications that can occur during or immediately after ESS, is mainly attributed to orbital hematoma or direct injury to the optic nerve. In contrast to such direct mechanical trauma caused during ESS, we report a case of acute loss of vision that followed ESS without a definite cause. A postulated mechanism for idiopathic optic neuropathy is that it is ischema resulted from vasospasm in the branches of ophthalmic artery due to topical use of vasoconstrictive agents. Otorhinolaryngologists should be aware that this condition may occur following an uncomplicated ESS procedure. When loss of sight is diagnosed postoperatively, patients should be given prompt ophthalmological consultation and possible causes should be considered.
