Why does a px adopt a CPH?
- Null zone : nystagmus
- Avoid Dip
- Always double, but turning casues the images to be so far apart the px can focus on one of the images
What is this?
- Limiation to the right ad and ab
Type A duanes
How do we manage her?
- If she decompensates then we can correct this, but for now nothing
- Small CHP, so no pain ect, so no intervention.
Explain this ? R: +5.00/-0.50x170 L: +2.75/-0.75x180 (Full Rx)
- Hyperopic
- Astigmatism
- Anisemetropia
If the px is patching then the amyblopic eye would be the right eye ; the higher rx/
DO px with microtopia have central suppression?
Yes
How can you detect microtopia?
- Va the absoulte best
- 4D prism base out best

What does the left eye have?
secondary strabismus ; due to the VA in the left eye is shit
px has light perception in the LE. what can we do to do some orthopic assessments?
1.CT: Corneal reflections
2. OM : can only do versions not ductions
3. PCT : Prism reflection test
why does px have a small limiation in abduction in the 3rd nerve?
could be due to surgery
how do we manage the 3rd nevre?
- ask what she wants, ptosis, vision or muscles
- when can we do ptosis surgery? knowing they will not get double vision if we took the eyelid away.
- so do strabismic management first then address the lids.
what we do to constrict the pupil?
Pilocarpine : this will make the VA better
aberent regeneration findings?
1.ptotis and lid retractions
2.effected eye will converge
3.
