Managing ET Flashcards
What are the 2 tx findings for infantile ET?
- Poor prognosis for normal BV
2. Surgical candidate
What is the goal for infantile ET tx?
Good cosmesis and peripheral fusion
What is the prognosis for accommodative ET?
Good if intermittent or of short duration
What is the tx for accommodative ET?
- Lenses
What 2 things should you consider if tx’ing an accommodative ET patient with lenses?
- Consider full cyclo Rx
2. Consider add at near if high AC/A
What is the prognosis for partially accommodative ET?
- usually good, but worse than fully accom. ET
Why should we follow-up with partially accommodative ET?
May have developed sensory anomalies
For partially accom ET, it’s treated with lenses and what 3 additional things?
- Prism
- Sx
- VT
What are the causes of acute onset comitant ET?
- Occlusion
- Physical/emotional shock/stress
- Idiopathic
- Neurological causes
What is the prognosis for acute onset comitant ET?
Good if not pathology
What is the tx for acute onset comitant ET?
Rx full plus w/ prism, VT or Sx
What is the initial treatment for ET?
Refractive lenses that correct RE and decrease size of ET
What is the 1st and 2nd step of improving monocular visual function?
- Treat amblyopia
2. Normalize monocular skills
When normalizing monocular skills, what 2 things are we working on?
- Accommodative Skills
2. Ocular motility therapy
After monocular skills are normalized, what’s the next step in managing ET?
- Develop normal peripheral fusion
What are the 3 steps to develop normal peripheral fusion?
- Eliminate AC
- Eliminate peripheral suppression
- Improve peripheral sensory/motor fusion
How can we eliminate AC?
- sensory stimulation of obj. angle in-instrument (if ET > 15-20pd)
- Motor stimulation (if ET < 15-20pd)
- Overcorrecting prism (any size ET)
When developing normal peripheral fusion, what size targets should we start with at the objective angle
Large targets
After normal peripheral fusion is developed, what 2 things should be worked on?
- Eliminate central suppression
2. Increase vergence ranges
After extending SM fusion to central vision, what do we work on next?
Establish binocular vision in free space
If the ET is greater than ___, sensory/motor fusion is very hard to control in free space.
15pd
