A Case of Orbital Encephalocele With Unique Malformations of the Brain and Eye

Colobomata of the Optic Nerve Sheath in Rats

“…difficulties, he attempted to classify colobomata of the optic nerve under three heads: (1) where the lesion is a coloboma of the choroid beneath the nerve, the nerve itself being normal and sharing only passively in the deformity; (2) where the lesion is a coloboma of the choroid and the nerve; (3) where the lesion is a coloboma of the nerve alone, the adjacent choroid being normal. Parsons and Coats (1906)reported a variation of type (3), in that, as well as there being retina in the optic nerve, the lamina cribrosa had given way at its temporal margin where an ectasia of the retina had occurred. TIhe scleral margin was involved also at this point.…”

A sphenoorbital encephalocele — clinical, radiological, and morphological findings

“…It is not always possible, however to make conclusions about the site of origin of an encephalocele from its histology. Sometimes, histology reveals only glial tissue without any trace of spatial origin [5,10]. It is also not always possible to determine the developmental period of the tissue of the encephalocele, according to the maturation of the tissue [3].…”
