Syndrome with characteristics of congenital microphthalmia and blindness, progressive spasticity, microcephaly, seizures and profound intellectual deficit. It has been reported in three children from three unrelated families. While imaging at birth is normal, follow-up studies show progressive atrophy involving the cerebral white matter and cortex, cerebellum, brainstem, and corpus callosum. The white matter changes extend into the subcortical region, leaving only small islands of remaining cortical tissue. [from
