Definitions Flashcards
Strabismus
misalignment of the eyes
Nystagmus
reflexive rapid movement of the eyeballs, often in response to turning the head
Myopia
decrease ability to see for distances
Presbyopia
difficulty with accommodation (ability to see something at a far distance and then quickly focus on something in close range, and vice versa)
Oculomotor Function
describes motor movements of the eyes, such as saccades, pursuits, convergence and accommodation
Visual Acuity
relates to the ability to see objects or the environment clearly at various distances
Visual Field
describes the extent of peripheral vision an individual has, which is typically tested in upper/lower quadrants in both the right and left visual field
Scanning
describes the ability to search for and locate desired information or objects either in written form or in the environment
Cerebellar lesions result in
ataxia and dysmetria
Suction plate and cup holder These assistive devices will help the client stabilize the plate and hold the cup during a meal.
ataxia
Many symptoms of Ataxia mimic those of being drunk, such as slurred speech, stumbling, falling, and incoordination. These symptoms are caused by damage to the cerebellum, the part of the brain that is responsible for coordinating movement.
dysmetria
lack of coordination of movement typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is a type of ataxia. It can also include an inability to judge distance or scale.
Dyskinetic CP
characterized by dystonia (Involuntary muscle contractions that cause repetitive or twisting movements.) and caused by a basal ganglia lesion.
Dystonia
fluctuating tone
Spastic CP
caused by a cerebellar lesion and is characterized by spasticity and hypertonia
Ataxic CP
caused by a cerebellar lesion and is characterized by hypotonia and ataxia
