Noncomitant Deviations Flashcards
This describes the complete loss or impairment of motor function.
Paralysis or Palsy
This describes slight or incomplete paralysis
Paresis
When doing ACT, you notice each eye move down when it’s uncovered. What type of deviation is this?
Dissociated Vertical Deviation
DVD is commonly associated with what finding?
Infantile ET (70% of cases)
This type of deviation is found when there’s over-elevation in ADduction.
Over-acting IO muscles
- bilateral is most common
What % of strabs have an A or V pattern?
30%
What is the most and least common types of AV patterns?
Most common = V-eso
Least common = A-exo
What is the etiology of A/V pattern strabs?
Oblique dysfunction
In a V-pattern strab, what is the UA and OA muscle?
UA = SO
OA = IO
**oblique abduct; too much abduction by IO
In A-pattern strab, what is the UA and OA muscle?
UA = IO OA = SO
If XT with A pattern, where do they have the most trouble? What about V pattern?
A = more trouble in downgaze
V = more trouble in upgaze
- both benefit from yoked prism
What 2 types of patterns would tilt their chin down?
A pattern -XT
V pattern - ET
What 2 types of patterns would tilt their chin up?
A pattern - ET
V pattern XT
This deviation describes restricted elevation of ADducted eye due to restriction of SO tendon at pulley.
Brown’s syndrome
- can’t look up and in
What will the results of a FD test be in a px with Brown’s syndrome?
(+) FD test
