Amblyopia, often called lazy eye, is a reduction of vision in one eye that is not correctable with glasses.
There are 5 types of amblyopia:
Anisometropic amblyopia—Vision in one eye differs from the other. This is often caused by a large difference in eyeglass prescription. The difference may be caused by one eye being more
than the other, or by large differences in
Visible misalignment (crossing) of one eye
Stimulus deprivation amblyopia—
Blockage of vision due to something in the eye, like a cataract
Cycloplegic refraction test—to assess how the eyeball displays and receives images produced by the lens of the eye
Retinoscopy—to determine a preverbal child’s eyeglass prescription
Prisms—to determine the amount of crossing between the 2 eyes
The sooner amblyopia is treated, the more favorable the outcome.
Treatment includes correcting visual obstructions, such as
and other visual abnormalities.
Talk to your doctor about the best option for you. These may include:
Atropine drops or ointment is placed in the non-amblyopic eye. This causes the sound eye to become unfocused and forces the use of the lazy eye.
Occlusive therapy involves using a patch over the unaffected eye, forcing the use of the lazy eye.
Bangerter foils are another option. The foils, which are made of thin vinyl, are placed over an eye glass lens, covering the unaffected eye. Just like with the patch, this forces the weaker eye to become stronger.
While there are no current guidelines to prevent amblyopia, vision screening can help to detect the condition at an early age. Children under age 3-5 years should be examined for eye problems.
