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.
