Bilateral temporal hemianopsia: It is a type of partial blindness with loss of vision in the outer half of both the right and left visual field. More detailed information about the symptoms, causes, and treatments of Bilateral temporal hemianopsia is available below.. Symptoms of Bilateral temporal hemianopsia. Prosopagnosia (from Greek prósōpon, meaning "face", and agnōsía, meaning "non-knowledge"), also called face blindness, is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making.   The commonest type of unpaired defect in cases of lesions of the optic radiation is known as the temporal crescent or half moon defect. The terms temporal crescent and half moon have reference to either one of the two areas which are temporal and peripheral to the binocular field of .

  Rahman and colleagues [2] describe another interesting case of sudden onset unilateral nasal hemianopsia respecting the vertical midline on formal testing that was found to be secondary to a posterior subcapsular cataract (which, of interest, was not limited to the temporal aspect of the lens capsule as one might expect).

Expert radiologists Bernadette L. Koch, MD and Bronwyn E. Hamilton, MD present more than cases across a broad spectrum of head and neck. All four cases (two men and two women, aged mechanical compression by enlarged, atherosclerotic carotid artery; can be unilateral or bilateral. 5, Loss of the medial portion of chiasma of the PCA is usually secondary to total occlusion of the vessel.2 The clinical features vary and may include pure hemianopsia,2 resemble. Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain is sustained, a deficit in attention to and awareness of one side of the field of vision is observed. It is defined by the inability of a person to process and perceive stimuli on one side of the body or environment, where that inability is not due to a lack of sensation. Efficacy of unilateral versus bilateral temporal artery biopsies for the diagnosis of giant cell arteritis. Am J Ophthalmol. ; (2) (ISSN: ) Boyev LR; Miller NR; Green WR. PURPOSE: To determine the utility of unilateral versus bilateral temporal artery biopsies in detecting the pathologic changes of giant cell arteritis.

Precise localisation of tumour impingement onthe chiasm or optic nerve was by:   There was a log afferent defect in the right Two cases of unilateral temporal hemianopsia book. The patient identified 13 of 15 AOH-R-R color plates with her left eye and 11 of 15 with her right eye. The pupil cycle time had returned to normal.

Temporal optic disk pallor persisted in the right eye. The unilateral nasal hemianopia remained (Fig. 2).Cited by: However, unilateral nasal hemianopsias are rare defects, documented to be associated with pituitary adenomas, temporal optic nerve lesions, and suprasellar aneurysms.1 Cataracts are known to.

The lesions were most commonly located in the occipital lobes (45%) and the optic radiations (%). Every type of HH, except for unilateral loss of temporal crescent and homonymous sectoranopia. A year-old girl was found to have temporal hemianopia of the left eye.

Her visual acuity was 20/20 OU and she had normal color discrimination bilaterally. Left afferent pupillary defect was present. Right-eye perimetry results were normal, but complete temporal hemianopia respecting vertical.

Hemianopsia is a loss of vision in half of the visual field of one or both eyes. Common causes are stroke, brain tumor, and trauma to the brain. o Anterior extension to the optic chiasm can result in a classic bitemporal hemianopsia, unilateral temporal hemianopsia, papilledema, or unilateral/bilateral decrease in visual acuity.

Classically, vision loss starts with a superior temporal field cut. However, the eccentric growth of these tumors can result in varying patterns and severity of vision loss, including decreased acuity, diplopia.

A Retained Temporal Crescent: Hemianopsia that occur in a specific location in the occipital lobe may result in a hemianopsia in which at the far temporal side of the hemianopsia, a crescent shape area of vision is retained. This usually is about 60 degrees out from straight ahead and extended to the 90 degrees from straight ahead.

Hand movements in a case of hemianesthesia following a lesion of the parietal lobe. Both unilateral and bilateral temporal lobe lesions have been described.

We report a case of a unilateral nasal hemianopia that was caused by compression of the left optic nerve by a sphenoid wing meningioma.

Histological examination revealed that the pathology of the meningioma was consistent with that of an atypical meningioma, which carries a guarded prognosis with increased chance of recurrence. Two children with a history of traumatic delivery developed severe temporal lobe epilepsy starting at age 4 and 10 respectively.

The main neurological finding was total homonymous hemianopsia. The CAT Scan showed a large localised hypodensity in the occipital region on one side consistent with an old infarction in that region. A case of unilateral hemianopsia in which the Wernicke hemianopsic pupillary reaction was present.

n loss of vision in either the whole left or the whole right half of the field of vision. Visual field defects respecting the vertical midline are a common occurrence associated with focal neurological lesions.

However, unilateral nasal hemianopsias are rare defects, documented to be associated with pituitary adenomas, temporal optic nerve lesions, and suprasellar aneurysms.1 Cataracts are known to depress the overall sensitivity of the visual field,2,3 but localised visual field.

Monocular temporal visual field loss from organic lesions is quite rare but has been reported in conjunction with compressive lesions at the optic nerve-optic chiasm junction.

This is the first report to demonstrate this visual field defect together with bowtie optic nerve hypoplasia.

Figure 3: The anatomy of hemispatial neglect.

A variety of cortical lesions can lead to the syndrome of hemispatial neglect, tending to center around the temporo-parietal junction (TPJ), angular gyrus (ang), inferior frontal gyrus (IFG), inferior parietal lobe (IFL), intraparietal sulcus (ips), middle frontal gyrus (MGF), supramarginal gyrus (smg), superior temporal gyrus (STG).

Homonymous hemianopia: challenges and solutions Denise GoodwinPacific University College of Optometry, Forest Grove, OR, USAAbstract: Stroke is the most common cause of homonymous hemianopia (HH) in adults, followed by trauma and tumors.

This patient presented with a dense right homonymous hemianopsia but no hemiparesis. She was cognitively intact, mentally alert, and had no speech or reading problems except for the effect of the visual field on reading.

Bilateral homonymous hemianopsia with sparing of central vision (BHHS) is a specific visual defect (2, 3, 19) caused in most cases by bilateral occipital infarction associated with arteriosclerosis ().We encountered a patient with BHHS caused by infarcts located bilaterally in the striate cortex as a result of tentorial herniation subsequent to severe head trauma, and we report this case here.

The damage caused by a unilateral retinal or optic nerve disease may result in monocular hemianopia because they involve the pre-chiasmal visual pathway. A retinal detachment, for example, located nasally, would give a temporal field defect in one eye.

Inversely, a temporal retinal detachment is manifested by a nasal field defect in the. Homonymous hemianopsia (HH) is the commonest form of acquired homonymous visual field defect.

The most common causes of HH are stroke, head injury and intracranial tumors [].HH has been related to neurosarcoidosis [].Symptomatic homonymous visual field defects are relatively rare in MS, encountered in 1% of patients.
