title: [Porencephaly as a cause of ophthalmologic symptoms].
abstract: Two cases of hypoplasia of the optic nerve associated with porencephaly and one case of porencephaly without ophthalmologic signs are described. The clinicopathological correlation of the double-ring sign is presented and the possible mechanism of optic nerve hypoplasia being a secondary degeneration is discussed.
