Myopia Control Flashcards
What is the best controller of myopia progression?
Atropine QHS
What’s better, atropine .1% or .01%?
Both drops are good, but 0.01% had less SEs and rebound myopia
The use of tropicamide and cyclopentolate in myopia control provided what type of results when studied?
Contradictory results
What happens if you undercorrect myopia to try and control the growth?
Undercorrecting myopia actually accelerates myopia progression
Bifocal lenses (including PAL) were only effective in controlling myopia in what group?
Pxs with Low accommadation and esophoria
What are some lifestyle changes that a px can do to control myopia progression?
- Read in the light
- Avoid short reading distance
- Don’t use nightlight
What type of contact lenses showed myopia control?
Biofinity MF D lens = Soft Bifocal Lens (+2.50 is best)
How do MF contract lenses decrease myopia progression?
Modifies peripheral rays that hit the back of the eye
Do RGPs help with myopia control?
Only helps during the first year
What is the 2nd most effective myopia control tx (after atropine)?
Orthokeratology
What is the theoretical, main cause of myopia progression?
In myopia, the peripheral rays defocus behind the retina, causing the eye to think it is too short and it grows
Ortho K produces what type of corneal shape to reduce the hyperopic defocus of the peripheral retina?
Oblate corneal shape
What is the largest risk factor for high myopia?
If both parents are myopic
Is sx recommended for trying to control myopia?
No!
What is the first tier of myopia control supported by the literature?
- Atropine, QHS
2. Ortho K, QHS
