Q

VIP testing

A

Establish a standard battery of tests to elicit information about each important function

Each diagnostic entity has identifiable characteristics, signs, and symptoms-look for them

These disorders may not exist in isolation (patients may present with multiple deficits)

Visual discrimination + spatial relations

  • visual closure
  • figure ground
  • form constancy
  • visual memory
19
Q

A

Visual motor integration

-fine motor skills

20
Q

A

Audturoy visual integration

21
Q

Observation of performance for VIP

A
  • vital to observe the way in which the child achieves a particular result
  • helps one to better understand the child’s abiltiy
  • aids in planning a treatment program
  • provides info into the degree of difficulty
  • evaluates any compensatory strategies used to complete a task
  • attention and cognitive style must be considered in the deign of a visio therapy program
22
Q

Reflective style

A

Work slowly and produce few errors

23
Q

Impulsive style

A

Work quickly and make more errors

24
Q

Z scores

A

Distance form the mean
0=equalvelnt of the mean
Higher=greater deviation from the mean
Positive=above average, negative=below average

25
Q

Scarred score

A

10 indicated that the child’s performance is probably average for his age

26
Q

Standard scores

A

A derived score with assigned a mean of 100 with a standard deviation of 15

27
Q

Percentiles

A
  • raw scores must be converted into percentile scores

- 50th percentile is equal to a scale score of 10 and standard score of 100

28
Q

Age equivalent

A
  • represents the Rae score that us normal for that age

- not used that often

29
Q

Analysts of VIP test results

A
  • significant deviation from the expected findgins indicate problems in that particular area
  • scores between the 15th and 50th percentile are considered suspicious findgins and may be clinically significant when compared to the child’s overall level of functioning
  • general rule: a score is significantly low if the patient scores below the 15th percentile on any given test (greater than 1 standard deviation)
30
Q

Diagnosis in VIP testing

A
  • analysis of case history
  • actual test results
  • observation of the child’s performance
  • review of all previous reports and testing
31
Q

Goals of optometric intervetion in VIP

A
  • primary role: diagnosis and treatment of underlying vision problems
  • foals of optometric intervention should be specific or problem oriented
  • optometrists do NOT directly treat a reading or learning problem
  • recognize that patients may need a variety of services
32
Q

ODs may provide..

A
  1. Comprehensive diagnostic services-primary care, visual efficiency, visual information processing
  2. Managemtn of treatment services-refractive correction and therapy for visual efficiency and VIP disorders
  3. Information to assist the educator in devising a more suitable educational program for the individual student relative to his/her visual problems
33
Q

37
Q

Limitation of abduction, adduction, or both

A

Duanes retraction syndrome

38
Q

Things about Duane’s retraction syndrome

A
  • congential condition with no clear etiology
  • remember to count the number of Ds
  • associated with globe retraction (enophthalmos) and narrowing of the palpebral fissure with aDDuction
39
Q

Browns syndrome

A
  • superior oblique tendon sheath syndrome
  • can be congenital or acquired
  • can be present with a small hypotropia in primary position
  • limited elevation during aDDuction
40
Q

NRC

A

Fovea of each eye has the same visual function

  • if the fovea of one eye is deviated compared to the other due to strab, diplopia and confusion will occur
  • if the fovea misalignment develops before age 5, the visual cortex will respond by developing ARC to elimate diplopia a d confusion
41
Q

ARC

A

A non fovea point of the deviated eye is linked to the fovea of the other eye

  • this ensures that the object will be perceived in the same direction by each eye, eliminating diplopia and confusion
  • only occurs under binocular conditions (monocular conditions=eccentric fixation)
42
Q

Angle of anomaly

A

Difference between the objective and subjective angle of deviation
