7 - Dx and Management Flashcards
the largest concern for accommodative and non-strabismic disorders is _
overcoming symptoms
2 symptom surveys:
Convergence Insufficiency Symptom Survey COVD QOL (Quality of Life)
Sequential Management Approach: (6)
Optical Correction of Ametropia Added Lenses Prism Occlusion VT Surgery
What should be the 1st consideration for all patients?
optical correction!! the foundation
by 6-8 years old, most patients are within _
+0.50 to +1.00
average cyclo refraction of infants is _
+1.00 to +2.50
at 3 months, 16% have hyperopia greater than +3.50; _ occurs and at 9 months, 3% have hyperopia greater than +3.50
rapid emmetropization
as patient gets older, _ to rx
more likely to rx for myopia or hyperopia?
more likely
myopia
with _, static ret and cyclo ret are usually the same
myopia
under 2% of children have myopia until _ years old when there is a consistent rise which levels off in teen years
8
increased risk for myopia with:
near work, little outdoor time, myopia parents, premature
minus lenses cause _ at near, which may take time to adapt to - secondary accommodative insufficiency
accommodation
when patient is XT (especially IXT), rx _
myopia
cycloplegic refraction will result in _, compared to ret
more +
if a patient is <5 years old and eso and hyperopic, rx _
if >6, rx _
full cyclo.. don’t need distance
cyclo - 1D
anisometropia, assess with _, rx _
cyclo, off cyclo - full rx
clinically significatn anisometropia is _
> 1D
if aniseikonia, consider _
CLs
added lenses can be used for _
distance OR near
are added lenses an effective treatment method if low AC/A
no
segment height location for
3-5 year old _
6-7 year old _
>8 year old _
mid pupil
lower pupil margin
lower lid margin
up to 15 months, instead of bifocal.. just _ SV glasses
over plus
Sheard’s Criterion states that in order for a patient to be comfortable, the compensating fusional vergence should be _
twice the phoria
Sheard’s Criterion works best for _
Percival’s Criterion works best for _
1:1 best for _
