Glaucoma is an optic neuropathy and glaucomateus damage proceeds from retinal ganglion cells to brain. A better understanding of retrobulbar damage will enable us to develop more efficient strategies and a more accurate understanding of glaucoma. We evaluated retrobulbar glaucomatous damage with favorable techniques for 1.5T MR imaging. Optic nerve damage and cortical hypofunction were shown with diffusion tensor MR and functional MR imaging, respectively. Correlations of the apparent diffusion coefficient with mean deviation, pattern standard deviation, retinal nerve fiber layer thickness in distal optic nerve and fractional anisotropy with ganglion cell counting in proximal optic nerves and correlations of retinal nerve fiber layer thickness with axial diffusivities in both ipsilateral and contralateral corpus geniculatum laterales and with fractional anisotropy in ipsilateral corpus geniculatum laterale were statistically significant.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
