At a visit in our clinic several months prior, vision O.S. A significant visual field defect was present in not only the left eye, consistent with the patients case history, but also in the right eye. Intracranial optic nerve, junctional and optic chiasm. His visual acuity recovered fully, but his visual fields only partially recovered. 6. Are there other neurological signs? Destruction causes transient ipsilateral conjugate deviation of the eyes (i.e., toward the lesion). It also receives fibers from the ipsilateral temporal hemiretina and the contralateral nasal hemiretina. [citation needed], Individuals with quadrantanopia often modify their behavior to compensate for the disorder, such as tilting of the head to bring the affected visual field into view. The cortical visual pathway projects from the primary visual cortex (Brodmann's area 17) to the visual association cortex (Brodmann's area 19). Invest Ophthalmol Vis Sci 2007 Oct;48(10):4445-50. The visual pathway. It is most often associated with stroke and is more severe and persistent following right hemisphere damage, with reported frequencies in the acute stage of up to 80%. Homonymous Superior Quadrantanopia Junctional Scotoma and Junctional Scotoma of Traquair, https://eyewiki.org/w/index.php?title=Compressive_Visual_Field_Defects&oldid=84398, Adults: breast, lung, unknown primary, prostate, melanoma, Children: neuroblastoma, Ewing sarcoma, leukemia, Rhabdomyosarcoma (embryonal type, children), Langerhans cell histiocytosis (<1% of all orbital masses), Fibromatosis (most common orbital lesion of infancy), Plasmacytoma/multiple myeloma (0.5% of all orbital masses), Benign (50%) - Benign mixed tumor (pleomorphic adenoma), Malignant (50%) - Epithelial carcinoma, Adenoid cystic carcinoma, Malignant mixed tumor, Metastasis, Neoplasm is the most common cause of chiasmal syndrome and is from both direct compression and inflammatory disruption of the vascular circulation to the chiasm, Pituitary Adenoma - most common cause of chiasmal lesion, Meningioma (including optic nerve sheath meningioma), Non-neoplastic etiologies can also cause direct compression at the chiasm, including, Vascular sources may cause compression and/or ischemia to the chiasm, Apoplexy - from either vascular sources or tumors, Aneurysm of anterior communicating artery or internal carotid artery, Trauma can rarely cause chiasmal syndrome from a frontal bone fracture and/or anterior skull base fracture and hematoma can act as a mass lesion. Neurology 2006 March 28;66(6):906-10. (6) Right lower quadrantanopia. Parietal lobe lesion (infarct, hemorrhagic stroke, trauma)on the side opposite the visual field defect. Remember: Nearly half of the nerve fibers cross at the optic chiasm, so the loss of visual field on one side is quite different than loss of vision in one eye.
