Background: In glaucoma the optic radiation may be affected by ascending degeneration and/or ageing. This study classified groups of patients who are distinguishable related to their age, retinal nerve fiber layer thickness (RNFL), axonal integrity (measured by fractional anisotropy and mean diffusivity) and demyelination (measured by radial diffusivity) of the optic radiations. The goal was to separate glaucoma-induced damage of the optic radiations from impairment caused by the ageing effect.Design: Prospective comparative observational study. Participants: Fourty-five patients diagnosed with glaucoma of different entities and 17 patients with vital papilla (mean age 57.5 ± 13.8 years).Methods: Multimodal MRI including diffusion tensor imaging (DTI) of the optic radiations and measurement of the RNFL thickness by Sp..
