Managing ET Flashcards
What is the prognosis & goal of treating infantile ET?
- Poor prog for normal BV
- Good cosmesis and peripheral fusion
What is the prognosis for accommodative ET?
Good if intermittent or of short duration
What is the prognosis for partially accommodative ET?
- usually good, but worse than fully accom. ET
For partially accom ET, it’s treated with lenses and what 3 additional things?
- Prism
- Sx
- VT
What is the initial treatment for ET?
Refractive lenses that correct RE and decrease size of ET
What are the steps to treat/manage ET?
- Spec Rx
- Improve monocular function
- Develop sensory and motor fusion
- establish BV in free space
- Maintain and monitor BV
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 S/M 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.
