Amblyopia Flashcards
It is the most common form of amblyopia
Strabismic amblyopia
It is a condition in which a primarily a defect of central vision.
Amblyopia
It is partly from the direct effect of image blur in the development of visual acuity.
Anisometropic amblyopia
It develops when unequal refractive error in the two eyes causes the image
Anisometropic amblyopia
It is a result from large, approximately equal, uncorrected refractive error in both eyes of a young child.
Isometropic amblyopia
Uncorrected bilateral astigmatism in early
childhood may result in loss of resolving
ability limited to chronically blurred
meridians.
Meridional amblyopia
It is usually caused by congenital or early
acquired media opacity.
Stimulus deprivation amblyopia
It is the least common condition but most damaging and difficult to treat.
Stimulus deprivation amblyopia
In bilateral cases acuity can be 20/200 or
worse.
Stimulus deprivation amblyopia
It is a form of deprivation caused by excessive therapeutic patching.
Occlusion amblyopia
It `allows the examiner to test the crowding phenomenon with isolated optotype.
Crowding bar or Contour interaction bars
Optical prescription for amblyopic eyes should correct the full refractive error as
determined with cycloplegia.
Refractive correction
It is the most powerful means of treating of
amblyopia by enforced use of the defective eye.
Occlusion and optical degradation
A lens that can be used as an alternative to full-time patching if skin irritation or poor adhesion proves to be a significant problem
Spectacle-mounted occluder or Special opaque contact lenses
It runs a small risk of perturbing binocularity.
Full time patching
