Endoscopic decompression of the optic canal for traumatic optic neuropathy
PURPOSE Traumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%-5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries. METHODS In this study, 11 patients treated in our hospital from January 2009 to January 2015 with the visual loss resulting from TON were ...
متن کاملOptic nerve injury in fracture of the canal.
A case of unilateral blindness following blunt injury to the skull is presented. The patient died 4 days after the initial injury, presenting the rare opportunity of a detailed histopathological study of the acute features of the condition. The findings are discussed in the context of current theories of the pathogenesis of optic nerve injury in fractures of the optic canal.
متن کاملIncidence of optic canal fracture in the traumatic optic neuropathy and its effect on the visual outcome.
OBJECTIVE To correlate the intraoperative endoscopic findings with high-resolution CT (HRCT) for the diagnosis of optic canal fractures (OCF). To compare the visual outcome of patients with different types of OCF and without. DESIGN A retrospective, comparative case series. PARTICIPANTS 1275 consecutive patients (1275 eyes) with indirect traumatic optic neuropathy (TON). METHODS Altogethe...
متن کاملCT demonstration of optic canal fractures.
Traumatic blindness is a well recognized entity with a guarded prognosis. Previous studies have variously reported the incidence of concomitant optic canal fractures and response to surgical therapy. With the advent of CT scanning, a new technique for study of these severely injured patients has become available. Over a period of 20 months, optic foramen fractures were demonstrated in 10 such p...
متن کاملIntracranial penetrating injuries via the optic canal.
Two cases of intracranial penetration of a plastic or wooden chopstick via the optic canal are described. CT scans showed the chopsticks as linear hypodense structures in the suprasellar cistern contiguous with the optic canal. In one case, MR imaging was performed, which clearly depicted the foreign body and adjacent brain structures. Although they are extremely rare, transorbital intracranial...
