About

What is Amblyopia
(Lazy Eye)?

Amblyopia is a treatable, neurodevelopmental form of vision loss.

It is caused when there is a disruption in binocular vision in infancy/toddlerhood either by misalignment of the eyes (also known as strabismus), or when one eye has a greater farsightedness/nearsightedness and/or astigmatism, or blockage of light, such as infantile cataracts. It typically occurs in one eye (but can occur in both eyes) even when best corrected with glasses or contacts.

What are the effects?

impaired depth perception Reduced eyesight

Those with Amblyopia will have reduced eye sight varying from:

MILD  MODERATE  SEVERE
(<20/25-20/40) (20/50-20/80) (worse than 20/100)

Equally important but often overlooked, those with Amblyopia have:

  • A deficiency in “binocular vision” which results in impaired depth perception
  • Poorer eye-hand coordination
  • Trouble with tripping and being accident prone
  • Deficits in visual information processing
  • Trouble with micro eye movement and reduced reading speed and comprehension

About

It is more common than you may think.

12 Million People with Amblyopia

Over 12 million people in the US alone are affected (about 3.5% of the US population).

It is preventable if the factors causing it are identified and treated in infancy or early toddlerhood, but it can be treated at any age.

Standard treatment

How is it usually treated?

The Standard Treatment for Amblyopia typically involves occlusion therapy of the non-amblyopic eye with:

Patching or occlusion therapy

OPTION A: Patching

Atropine Drops

OPTION B: Atropine Drops

Though very low cost, research shows these treatments have many limitations and negative side effects.

The Facts

Research shows there are consequences to standard treatment.

With patching or Atropine drops, there are consequences:

 Visual

  1. Eye sight improves, but even with good compliance, will often regress when discontinued
  2. Patching does not treat the underlying binocular vision problem
  3. Overall this treatment can have poor or marginal results

Emotional

  1. Often experiences bullying, teasing, emotional upset, frustration, anger and general unhappiness
  2. In need of more parent attention associated with the child’s treatment

The Facts

Research shows that standard treatment may not last.

The research suggests:

Standard treatments for Amblyopia

Once discontinued the improvements in eyesight diminish over time

Standard treatments for Amblyopia not effective past age 10

It is not as effective past age 10

Negative side effects

Has many negative side effects including psycho-social and emotional

The Facts

New research shows there is a better way.

There is good news! There is an Advanced Treatment that is evidence-based and proven effective for nearly all ages.

The Advanced Treatment:

  • Corrects the binocular vision problem, therefore standard patching/drops is not typically required
  • Gives the patient the ability see in 3-D and experience depth perception
  • Results occur much faster
  • Has no negative side effects

Introducing

Binocular Vision Therapy.

Binocular Vision Therapy is a proven effective treatment for amblyopia. It involves office-based optometric vision therapy (along with home oriented activities) guided by the doctor and vision therapist utilizing devices, prisms, lenses and dichoptic filters to treat the underlying suppression and related developmental vision delays plus help the two eyes to work together.
