Effect of scuba-diving on optic nerve and sheath diameters
Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated. Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
متن کاملMorphometric characteristics of central retinal artery and vein endothelium in the normal human optic nerve head.
PURPOSE This study documents the morphometric features of arterial and venous endothelia in the different laminar regions of the normal human optic nerve head and speculates on the hemodynamic characteristics of the central retinal artery (CRA) and central retinal vein (CRV). METHODS Twenty normal human eyes were used. Microcannulation techniques were used to label the cytoskeleton and nuclei...
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 کاملA histopathologic and morphometric differentiation of nerves in optic nerve hypoplasia and Leber hereditary optic neuropathy.
OBJECTIVES To characterize and quantitate optic nerve histopathologic and morphometric differences between optic nerve hypoplasia (ONH) as an early and congenital form of intrinsic axonal loss and Leber hereditary optic neuropathy (LHON) as a late and acquired form of intrinsic axonal loss. MATERIALS AND METHODS Optic nerves from 3 sources were examined: a 42-year-old healthy woman (control),...
متن کاملEndoscopic 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 ...
