Amblyopia Flashcards
_____ is the most common form of amblyopia
Strabismic amblyopia
__________ result from large, approximately equal, uncorrected refraction error in both eyes of a young child
Isometropic amblyopia
__________ directly measures acuity in children 3-6 years old
Modified snellen technique
Other term for crowding bar is _________
Contour interaction bars
_______ is the most powerful means of treating of amblyopia by enforced use of the defective eye
Occlusion therapy
Complete or partial unresponsiveness to treatment occasionally affect younger children but often occurs in patients older than ___ years
5
__________ capable of producing amblyopia require surgery without unnecessary delay
Cataracts
Allow the examiner to test the crowding phenomenon with isolated optotype
Crowding bar
A test estimating the relative level of vision in the two eyes for children with strabismus who are under the age of about 3
Binocular fixation pattern
It is primarily a defect of central vision
Amblyopia
Amblyopia results to _______ , ________ , and _________
Strabismus, anisometropia or high bilateral refractive error and stimulus deprivation
It develops when unequal refractive error in the two eyes causes the image on the one retina to be chronically defocused
Anisometropic amblyopia
Uncorrected bilateral astigmatism in early childhood may result in loss of resolving ability limited to chronically blurred meridians
Meridional amblyopia
Optical prescription for amblyopic eyes should correct the _______ full refractive error as determined with cycloplegia
Full
_________ can be used as an alternative to full-time patching
Special opaque contact lenses or spectacle-mounted occluder
