Visual Pathway: From 1 Different Sources
see optic nerve.
See VISION.... visual acuity
An agreed and explicit route an individual takes through health and social care services. Agreements between the various providers involved will typically cover the type of care and treatment, which professional will be involved and their level of skills, and where treatment or care will take place. See also “care plan”; “care programme”.... care pathway
A multidisciplinary set of daily prescriptions and outcome targets for managing the overall care of a specific type of patient, e.g. from pre-admission to post-discharge for patients receiving inpatient care. Clinical pathways are often intended to maintain or improve quality of care and decrease costs for patients in particular diagnosis-related groups.... clinical pathway
A treatment protocol based on a consensus of clinicians that includes only those few vital components or items proved to affect patient outcomes, either by the omission or commission of the treatment or the timing of the intervention.... critical pathway
Stimulation of the retina of the EYE with light causes changes in the electrical activity of the cerebral cortex (see BRAIN). These changes can be measured from outside the skull and can give valuable information about the state of the visual pathway from the retinal ganglion cells to the occipital cortex. Not only can it determine that function is normal, it can also help to diagnose some causes of poor VISION.... visual evoked response
See visual acuity.... acuity, visual
an extra electrical conduction pathway between the atria and ventricles, anatomically separate from the *atrioventricular node, that predisposes to *re-entry tachycardia. The pathway conducts faster than the atrioventricular node, giving rise to pre-excitation recognized by a characteristic delta wave at the beginning of the QRS complex on the electrocardiogram in normal rhythm. The presence of this pathway, with the occurrence of intermittent tachycardias, is known as the *Wolff-Parkinson-White syndrome.... accessory pathway
the route that a patient takes through the health-care system, from first admission to a hospital or treatment centre to final discharge. This may consist of one or more *spells in particular hospitals and one or more *finished consultant episodes. For example, a patient admitted to a district general hospital, transferred to a tertiary hospital for a specialist procedure, and then transferred back to the district general hospital for recovery would experience one continuous patient pathway but three spells.... continuous patient pathway
a multidisciplinary plan for delivering health and social care to patients with a specific condition or set of symptoms. Such plans are often used for the management of common conditions and are intended to improve patient care by reducing unnecessary deviation from best practice. See clinical governance.... integrated care pathway
see rhodopsin.... visual purple
(visual reinforced audiometry, VRA) a behavioural test of hearing for children aged approximately 6 to 30 months in which the subject sits between two calibrated loudspeakers. A sound is generated from one loudspeaker. Children who turn towards the sound are rewarded by brief illumination of a toy adjacent to the loudspeaker. Older children can be tested with headphones, rather than using the loudspeakers, to enable each ear to be tested separately. The test can be adapted for use with older subjects who have learning disabilities.... visual reinforcement audiometry
