In view of the panhypopituitarism and visual field defects magnetic resonance imaging of the brain was ordered (figure). Magnetic resonance imaging showing the pituitary tumour 1. What are the radiological findings? 2. What are the differential diagnoses? 3. Why does this ...
The origin of visual field defects If strokes or injuries cause damage to the area of the brain that processes the information of the visual sense, this results in a visual field defect. The area most commonly affected is the primary visual cortex, the first processing point for ...
Identify and explain how lesions at different points along the pathway can manifest as visual field defects. Visual field deficits Types of lesion can be classified by it location in relation to the optic chiasm:1. Pre-chiasmal lesion- Affects visual field ipsilaterally (monocular)- Impairment can...

(SOAP) format and concentrate on common and uncommon visual defects encountered in practice. Each case presentation documents history corroborating the cause and the corresponding visual defect in the style of a problem-oriented clinical record. Virtually every method of manual and automated field-...
Study links severe visual field defects, poor medication adherence Glaucoma patients who showed poor medication adherence were at increased risk of having severe visual field defects, a study found. Full Story

In contrast, defects that involve the visual fields of both eyes often (but not always, as in the case of glaucoma) reflect disease processes at the optic chiasm or farther back in the brain. The specific condition where visual field defects are present in corresponding halves of the right ...
The object of the invention is to eliminate the various aforementioned defects of the systems of the prior art and it devises an intelligent digital audiovisual system which allows better ergonomics while reducing the risk of failure by reducing the number of mechanical parts. This object is achiev...
