[Congenital hypoplasia of the optic nerve (author's transl)].

The authors investigated 7 children with developmental anomalies of the optic disc. In all cases a typical pattern of hypoplasia was observed. In all patients was found a very marked impairment of visual acuity or even blindness of the affected eye with most frequently squint and nystagmus. Besides ophthalmological investigation, neurological examination were carried out in these children and the Wassermann reaction was determined, together with tests for toxoplasmosis and radiograms of the optic foramina.
