We report on a patient with an asymmetrical bilateral developmental anomaly
of the occipital lobes which led to a loss of almost the entire visual fie
ld. MRI and (18)FDG scans confirmed the presence of a larger lesion of the
visual cortex of the right hemisphere. The patient recovered parts of her v
isual field with time as measured by computerized perimetry, progressing fr
om near blindness of the right eye to a remarkable recovery of vision. Beca
use the patient had neonatal damage to both occipital lobes, we hypothesize
d a cortical plasticity process similar to that described in subhuman speci
es.
