Nondecussating retinal-fugal fiber syndrome: Clinical and neuroimaging clues to diagnosis.

Abstract:

:We report the clinical details and imaging findings for a case of nondecussating retinal-fugal fiber syndrome or isolated achiasma in a 4-year-old female child. Findings included the isolated absence of optic chiasm with unremarkable rest of the optic pathway and midline structures in a child presenting clinically with see-saw nystagmus. Clinically congenital see-saw nystagmus, "mirror reversal" of visual field representation and interocular ipsilateral asymmetry on monocular visual evoked potential point toward achiasma and warrant further evaluation with magnetic resonance imaging (MRI). Isolated achiasma is a rare condition that may remain undiagnosed unless MRI is done.
