Choroidal lacunae and Aicardi's syndrome.

Three children with flexion spasms and an ophthalmologic picture characterised by choroidal lacunae are described. Aicardi's syndrome was diagnosed in two cases. A diagnosis of Aicardi's syndrome should include CT scan and/or pneumoencephalographic findings of partial or total agenesis of the corpus callosum and/or other anomalies of the interhemispheric structures. Choroidal lacunae are not entirely pathognomonic.
