		hemianopsia and glaucoma after a discussion of the bibliographic references to the few observations on the simultaneous occurrence of hemianopsias and glaucoma the author states on the basis of his experiences the following points homonymous hemianopsias occasionally take place in glaucoma, although no direct relation can be established between the former and the glaucoma.
		a homonymous hemianopsia has to be taken into consideration also in the event of a sudden impairment of the visual field in a glaucomatous patient or when the hemianopic defect supervenes in addition to the visual field defect due to glaucoma.
		whether the binasal hemianopsia is the result of the gradual development of a glaucomatous visual field with nasal defects or whether it constitutes an independent symptom to a certain extent, cannot always be clarified in the individual case.

	Biomedical terms Hemianopsia
		Homonymous hemianopsia refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field.
		Binasal hemianopsia consists of loss of vision in the nasal hemifields of both eyes.
		Bitemporal hemianopsia is the bilateral loss of vision in the temporal fields.

		Hemianopsia means loss of vision in half of the visual field of both eyes.
		Homonymous hemianopsia means that the same side of the visual field for each eye is defective.
		Homonymous hemianopsia occurs from lesions of the entire optic tract, the lateral geniculate body, the optic radiation, or the entire visual cortex of the contralateral hemisphere (Fig.

		Homonymous hemianopsia implies both a post-chiasmal lesion and a lesion on the side of the brain opposite the compromised half of the binocular field.
		Bitemporal hemianopsia, sometimes called 'tunnel vision' in lay terminology, is indicative of direct or indirect insult of the sagittal portion of the optic chiasm -- where the nasal fibers of the two eyes, as they cross, lie in close proximity.
		The hypothetical patient, able to see the central and paracentral (near peripheral) fields, may not be conscious of the loss (consider general unawareness of the blind spot); and he or she may be surprised to learn of the perimetry data.

		The same is true of the rare,but extant, binasal hemianopsia.) By convention, a field defect is named for the field, not the pathway nor the projection onto the retina.
		Hemianopsia is a blindness or reduction in vision in one half of the visual field.
		Hemianopsias can be caused by conditions such as stroke, tumors and trauma.

		Binasal hemianopsia is the medical description of a type of partial blindness that is associated with certain lesions of the eye, and of the central nervous system, such as congenital hydrocephlus.
		The absence of vision in half of a visual field is described as hemianopsia.
		Nasal retina is responsible for temporal visual field so it leads to bitemporal hemianopsia.

		Binasal hemianopsia is when affection of chiasma concerns uncrossed fibers, and this type of hemianopsia is extremely rare, as in this case two opposite (symmetric) parts of chiasma must be involved (see images below), for instance calcification of both internal carotid artery at ephippium (Turkish saddle):
		In case of affection of visual tracts homonymous [(equi)lateral] hemianopsia arises.
		Small fl spot within the field of vision of left eye is left blind spot, as you already know, but right-side blind spot is within lost part of field of vision of right eye.

	NeuroAnatomy Glossary
		A rare heteronymous hemianopsia that could occur in the unlikely event that there are aneurysms of both internal carotid arteries at the level of the optic chiasm thus compressing the chiasm laterally.
		A heternomymous hemianopsia consisting of loss of vision in the temporal visual fields usually caused by damage to the central portion of the optic chiasm.
		Examples of visual field defects include: homonymous hemianopsia, heteronymous hemianopsia (such as binasal hemianopsia, bitemporal hemianopsia), homonymous quadrantanopsia.

	Chapter 7 - Vision
		Loss of half of the visual field is called hemianopsia.
		If the visual field is half-lost on either the right or the left, as for example in left optic tract section, Figure 7-19d, the loss is called homonymous hemianopsia, in this case, right homonymous hemianopsia.
		A quadrantanopsia results from interruption of either the superior or inferior optic radiation (clinically this usually involves a lesion in either parietal or temporal cortex) or alternatively from a partial lesion of the calcarine cortex, lower quadrants in the lingual gyrus, upper in the cuneate gyrus (Fig.
