The most common application for this is the treatment of strabismus. By moving the image in front of the deviated eye, double vision can be avoided and comfortable binocular vision can be achieved. Other applications include yoked prism where the image is shifted an equal amount in each eye.
The Peli Lens is a mobility aid for people with homonymous hemianopia. It is also known as “EP” or Expansion Prism concept and was developed by Dr. Eli Peli of Schepens Eye Research Institute in 1999. It expands the visual field by 20 degrees.
The Brunnstrom Approach sets out a sequence of stages of recovery from hemiplegia after a stroke. It was developed by the Swedish physical therapist Signe Brunnström, and emphasises the synergic pattern of movement which develops during recovery.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Patients who present with symptoms of a lacunar stroke, but who have not yet had diagnostic imaging performed, may be described as having lacunar stroke syndrome ( LACS ). Much of the current knowledge of lacunar strokes comes from C. Miller Fisher 's cadaver dissections of post-mortem stroke patients.
Blood pressure reduction of 10 mmHg systolic or 5 mmHg diastolic reduces the risk of stroke by ~40%. [108] Lowering blood pressure has been conclusively shown to prevent both ischemic and hemorrhagic stroke. [109] [110] It is equally important in secondary prevention. [111]
New research published in the journal Neurology is reporting an association between regularly eating ultra-processed foods and the risk of cognitive decline as well as stroke.
Partial anterior circulation stroke syndrome ( PACS) refers to the symptoms of a patient who clinically appears to have had a partial anterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.
A brainstem stroke syndrome falls under the broader category of stroke syndromes, or specific symptoms caused by vascular injury to an area of brain (for example, the lacunar syndromes ). As the brainstem contains numerous cranial nuclei and white matter tracts, a stroke in this area can have a number of unique symptoms depending on the ...
