Computer-assisted interpretation of resolution visual fields was performed in 147 normal subjects and 174 consecutive patients with known chiasmal or retrochiasmal lesion. The program identified 99% of normal subjects, and provided support for the correct diagnosis in 64% of patients with chiasmal and 83% of patients with retrochiasmal lesions. In conclusion, computer-assisted interpretation of resolution visual fields can provide considerable support to the final diagnostic decision in patients with lesions of the visual pathways.
