Aim:
Establish if f-MRI and DTI are valid (objective) tools to evaluate postchiasmatic
damage. Materials and methods: 7 patients with HVFDs underwent to a neuro-psycological
evaluation. A f-MRI and DTI sequences were applied to study the visual
activation and the optic radiation. Two patients underwent to a visual
rehabilitation treatment. Results: In all patients did not show an activation
in the visual cortex ipsilateral to the injury. The contralateral visual area
showed a normal pathway of activation. In the two patients treated, higher
activation in the contralateral visual areas was observed. Conclusions: F-MRI
and DTI are valid tools to study HVFDs.
