Visual field defects: these are common but often asymptomatic. Bitemporal hemianopia is the classic abnormality but any unilateral or bilateral visual field defect may occur.
Lesions at the chiasm These classically produce a bitemporal hemianopia. If they spread up from below (for example, pituitary tumours ), the defect is worse in the upper field.
Includes bitemporal inferior quadrantanopia progressing to bitemporal hemianopia and optic atrophy. Children rarely become aware of visual symptoms until advanced and irreversible...
A lesion at the optic chiasma, such as a pituitary adenoma, classically causes a bitemporal hemianopia (as decussating fibres are affected). A lesion posterior to the optic chiasm will cause ...
Bilateral severe sight impairment: methyl alcohol, tobacco amblyopia; neurosyphilis. Bitemporal hemianopia: optic chiasm compression - eg, internal carotid artery aneurysm, pituitary adeno...
Loss of vision in both temporal fields (bitemporal hemianopia) - occurs from lesions compressing the optic chiasm (eg, pituitary tumour or craniopharyngioma).
Visual field defects: the most common defect is a bitemporal hemianopia. Due to excess of GH: Gradual change in appearance due to the effects on cartilage and soft tissues: enla...
Visual disturbances (classically, a bitemporal hemianopia (lateral visual fields) or upper temporal quadrantanopia). Cranial nerve palsies .
The following symptoms are encountered relatively commonly as a result of neurological involvement: Facial numbness, dysphagia, hoarseness, headache, visual field defects , polydipsia, hearing i...
Occasionally, a secreting pituitary tumour can cause bitemporal hemianopia. Inflammatory and autoimmune conditions [ 4 ] Connective tissue disorders Those disorders which particula...
It is classically seen with space-occupying lesions in the suprasellar region (there will also often be a bitemporal hemianopia). It is also associated with optic nerve hypoplasia, brain st...
These may include: Bitemporal superior quadrantic field defect, which is classic. There may be a contralateral homonymous hemianopia if the optic chiasm is affected differently.
Homonymous hemianopia. Dysphasia. Posterior circulation ischaemia: [ 2 ] Motor deficits (weakness, clumsiness, or paralysis of any combination of arms and legs, up to quadr...
Convulsions - status epilepticus has been reported. [ 11 ] Blurred vision, hemianopia, visual neglect, hallucinations, cortical visual impairment. Fundoscopy often shows papilloedema...
Distinctive facies: Broad forehead, bitemporal narrowing, periorbital fullness. Stellate iris pattern, strabismus. Short nose with broad nasal tip.
Possible neurological signs include hemiparesis, weakness of the lower limbs, sometimes bilaterally, aphasia, ataxia, chorea and hemianopia. Specific cranial nerve lesions can include vest...
Posterior cerebral artery syndromes: Contralateral hemianopia with macular sparing. Clinical syndromes and scenarios Various different combinations of signs and symptoms hav...
There may be a hint of male pattern alopecia with slight bitemporal recession. The pubic hairline may extend up towards the umbilicus in a typical male pattern.
Vertebrobasilar territory If the ophthalmic cortex is involved there will be a homonymous hemianopia that may present purely as ignoring one side of the visual field. There may be bi...
Up to 6/24 with moderate restriction of visual field, opacities in the media or aphakia. 6/18 or better with a gross field defect (eg, hemianopia) or a marked constriction of the field (eg...
