dc.description.abstractPurpose To analyze the correlation between structural characteristics of intraorbital optic nerve (ION) and lateral geniculate nucleus (LGN) measured by 3-Tesla magnetic resonance imaging (3T MRI), and the severity of glaucomatous damage. Methods In this cross-sectional study, 41 glaucoma patients and 12 age-and sex-matched controls underwent standard automated perimetry (SAP) and frequency doubling technology (FDT) as functional evaluationen

dc.description.abstractand 3T MRI. Structure-structure and structure-function correlation were performed using bootstrap resampling method for clustered data. Results The ION mean diameter and cross-sectional area were different between glaucoma and control groups at 5mm and 10mm (all, p <= 0.011) from the globe, but not at 15mm (both, p >= 0.067). LGN height was significantly lower in glaucoma group (p = 0.005). OCT rim area and functional parameters (SAP and FDT) correlated significantly with all ION segments, showing stronger correlations at 10 and 15 mm. ION parameters at 10 and 15 mm presented mild-to-moderate correlation with OCT peripapillary nerve fiber layer thickness, and ION at 15mm had mild association with the neuroretinal rim area on stereophotographs. Although LGN height was significantly smaller in glaucoma group (p = 0.005), LGN parameters were not associated with any ocular structural or functional parameter. Conclusion Assessment of central and peripheral nervous systems using 3T MRI confirmed that glaucoma patients had smaller ION dimensions and LGN height compared to the control group. In general, ION dimensions presented mild to moderate correlations with functional and ocular structural parameters. Although ION had significant correlations at any distance from the eye, the ION distal locations correlated better with OCT results and functional parameters. However, LGN parameters were not associated with functional or ocular structural parameters.en
