Congenital achiasma
Congenital absence of optic chiasma
A rare genetic non-syndromic cranial nerve and nuclear aplasia malformation. The disease is 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.
