The aims of this study were 1) To evaluate retinal nerve fiber layer (fRNFL) thickness and ganglion cell layer plus inner plexiform layer (GCIPL) thickness at the fovea in eyes affected with traumatic optic neuropathy (TON) compared with contralateral normal eyes, 2) to further evaluate these thicknesses within 3 weeks following trauma (defined as "early TON"), and 3) to investigate the relatio...
OBJECTIVE To study the effects of timing of vitrectomy performed for open-globe injury patients on the thickness of retinal nerve fiber layer (RNFL). METHODS A total of 120 patients with traumatic optic neuropathy (TON) were selected and divided into a treatment group and a control group by random draw (n=60). Vitrectomy was performed within one week upon injury for treatment group and after ...
PURPOSE To compare the optical coherence tomography retinal nerve fiber layer and macular thickness measurements for detection of progressive axonal loss following acute traumatic optic neuropathy in a longitudinal study. METHODS Three patients with unilateral traumatic optic neuropathy were evaluated sequentially after trauma. Macular and retinal nerve fiber layer thickness measurements were...
BACKGROUND The purpose of this study was to determine the predictive value of flash visual-evoked potentials (VEP), relative afferent pupillary defect, and presence of orbital fractures in patients with traumatic optic neuropathy. METHODS A prospective study was conducted in 15 patients with indirect traumatic optic neuropathy. All patients underwent a thorough ophthalmic examination. Initial...
therapeutic effects of high dose intravenous prednisolone on methanol induced toxic optic neuropathy
background: the effects of high dose steroids for the treatment of methanol optic neuropathy was evaluated in this study. methods: in an interventional case series, 9 patients with a history of sudden visual loss after an ingestion of homemade alcoholic beverages were included in the study. the patients received 250 mg intravenous methyl prednisolone every 6 hours for 4 days continued with oral...
