[Oculo-cerebral dysplasia: aplasia of the optic nerve with familial microphthalmos and cryptophthalmus. Clinical and computer tomography study]. / Okulo-zerebrale Dysplasie: Aplasia nervi optici sowie familiärer Mikr- und Kryptophthalamus. Eine klinische und computertomographische Untersuchung.

The authors report on two siblings with severe malformations of the eyes. The 16-year-old girl has bilateral microphthalmus with aplasia of the right optic nerve and a Dandy-Walker cyst of the cerebellum. The right eye has no optic disk or retinal vessels. Her 13-year-old brother has unilateral aplasia of the optic nerve with cryptophthalmus and contralateral microphthalmus. In a computer tomography examination no optic nerve could be demonstrated on the left. The presence of an oculocerebral dysplasia in a brother and sister with healthy parents suggest an autosomal-recessive mode of inheritance of the aplasia of the optic nerve with microphthalmus and/or cryptophthalmus.

[Cortical blindness following arteria vertebralis angiography (author's transl)]. / Komplikationen der Vertebralisangiographie. Bericht über 6 Fälle von Rindenblindheit

Six patients suffered from cortical blindness following vertebral artery angiography. A connection of the incident with the technical procedure or a particularly great amount of applied contrast material, could not be seen. Vasospasm, stasis of contrast material in the arteria calcarina and a toxic lesion seem possible explanations, because the cortical blindness was fully reversible in all cases within some hours or days. Signs for an arterial embolisation did not exist, a finding, which is consistent with the literature.
