Optic atrophy and visual loss in craniometaphyseal dysplasia

Four members of one family had craniometaphyseal dysplasia. Two of the four had severe optic atrophy with profound loss of vision as a complication of this disorder. Optic nerve decompression attempted in one patient may have caused a reduction in the vision of that eye. Eight years later this patient underwent craniofacial surgery uneventfully for contouring of her facial and cranial bones, but osteotomies and intracranial surgery were specifically avoided because of bony over-growth in the foramen magnum region.
