Congenital achiasma is a rare, genetic, non-syndromic cranial nerve and nuclear aplasia malformation characterized by the congenital absence of the optic chiasm, resulting from the failure of the optic nerve fibers to cross over and decussate to the contralateral hemisphere, leading to decreased vision, strabismus and congenital nystagmus in infancy. Is a True Optic chiasm disorder Inferred relationship Some
A rare, genetic, eye disease characterized by foveal hypoplasia, optic nerve misrouting with an increased number of axons decussating at the optic chiasm and innervating the contralateral cortex, and posterior embryotoxon or Axenfeld anomaly (indicating anterior segment dysgenesis), in the absence of albinism. Patients present congenital nystagmus, decreased visual acuity, refractive errors and, occasionally, strabismus. Microphthalmia and retinochoroidal coloboma may also be associated.
