37 Possible Causes for Thin Optic Chiasm

  • Infantile Neuroaxonal Dystrophy

    We saw four patients with a thin optic chiasm.[ncbi.nlm.nih.gov]

  • Pachygyria-Mental Retardation-Seizures

  • Septo-Optic Dysplasia

  • Chiasmal Syndrome

    Radiologic studies demonstrated fractures in the fronto-ethmoid and sphenoid bones and thinning of the optic chiasm. No hypothalamic-pituitary abnormality was detected.[ncbi.nlm.nih.gov] Topical diagnosis: the optic chiasm. In: Glaser JS. Neuro-ophthalmology, 3rd ed. Philadelphia: Lippincott, 1999:31–33.)[medtextfree.wordpress.com] At craniotomy, major stretching, distortion, and thinning of the nerves and chiasm are commonly encountered, shedding little light on the mechanisms of impairment of function[medtextfree.wordpress.com]

  • Infantile Neuroaxonal Dystrophy 1

    Related to these symptoms is optic atrophy and a thinning of the optic chiasm, as observed by Nardocci et al. (1999).[breathepsychology.wordpress.com]

  • Microphthalmos

    […] nerves and chiasm, agenesis of the septum pellucidum, thinning of corpus callosum, and a normal pituitary infundibulum.[ncbi.nlm.nih.gov] Orbital and cranial computerized tomographic scanning and magnetic resonance imaging demonstrated bilateral microphthalmos and presumed retinal dysplasia, hypoplasia of the optic[ncbi.nlm.nih.gov]

  • Optic Neuropathy

    GCC measurements on OCT strongly correlate with visual field defects from optic chiasm compressive lesions and may help with regard to prognosis following treatment.[ncbi.nlm.nih.gov] Interestingly, some patients experience almost complete recovery of visual fields despite considerable GCC thinning, and others may have GCC loss before they develop demonstrable[ncbi.nlm.nih.gov]

  • Cysticercosis

    Sagittal MR imaging revealed an extraaxial cystic lesion with displacement of the hypophysis lateral and dorsal to the third ventricle and optic chiasm; extreme thinning of[ajnr.org] chiasm.[ajnr.org] Extreme thinning of the wall limiting the sphenoid sinus, secondary to the compression of the sellar structures, was present ( Fig 1C ).[ajnr.org]

  • Isolated optic nerve hypoplasia

    Coronal T1-weighted MRI shows diffuse thinning of the optic chiasm in bilateral optic nerve hypoplasia and focal thinning or absence of the side of the chiasm corresponding[entokey.com] The diameter of the intracranial optic nerve and thinning of the optic chiasm can be assessed on MRI scans.[eyewiki.aao.org] […] and attenuation of the corresponding prechiasmatic intracranial optic nerve ( Fig. 51.3 ).[entokey.com]

  • Haddad Syndrome

    The diameter of the intracranial optic nerve and thinning of the optic chiasm can be assessed on MRI scans.[eyewiki.aao.org]
