Amblyopia "Lazy Eye"

About Amblyopia

Amblyopia or “lazy eye” is a neuro-developmental vision problem that occurs during infancy and early childhood. Those with amblyopia experience reduced eyesight typically in one eye, even when best corrected with glasses or contacts. Left untreated, amblyopia can affect a child’s self-image, work, school, sports, friendships and may also lead towards depression.*

Details

When the ability to focus both eyes (binocular vision) is disrupted during early childhood development, the brain turns off or suppresses the incoming signals from the affected eye. Amblyopia occurs when vision development is disrupted in one of the following ways:

  1. Strabismic Amblyopia – This common form of amblyopia occurs when the eyes are misaligned, a condition known as strabismus. To avoid double vision, the brain shuts off or suppresses the weaker eye.
  2. Refractive Amblyopia –This form of amblyopia occurs when one eye has significantly uncorrected nearsightedness or farsightedness. When this happens, the brain favors the eye with better vision and shuts off or suppresses the weaker eye.
  3. Deprivation Amblyopia –This form of amblyopia occurs when light is blocked from entering an eye, such as cataracts or astigmatism. As a result of the obstruction, one eye becomes weaker, and the brain favors the eye without the obstruction, turning off or suppresses the weaker eye.

Amblyopia affects over 12 million people in the US alone (about 3.5% of the US population) and often goes undetected. However, this condition can be easily identified by a comprehensive eye health and vision evaluation. Those with amblyopia may have reduced eyesight varying from:

  • Mild               20/25 – 20/40
  • Moderate      20/50 – 20/80
  • Severe          worse than 20/100

Symptoms typically include:

  • Squinting or shutting an eye
  • Impaired depth perception
  • Poor eye-hand coordination
  • Tripping and/or accident prone
  • Trouble with micro eye movement
  • Slower reading speed and comprehension

Treatment – Beyond Patching

Until recent advancements, treating amblyopia with an eye patch was the general model of care. However, patching: 

  • Is very uncomfortable for the patient
  • Has multiple negative side effects
  • Has limited results based on age and usually not recommended past age 10
  • Does not usually develop the patient’s ability to obtain normal binocular vision with depth perception

Now there are better evidence-based methods for treating amblyopia that goes beyond patching.  

At Wow Vision Therapy, we are a leading developmental and rehabilitative vision therapy practice. Our doctors and board-certified vision therapists treat amblyopia with intensive office-based vision therapy for more effective results. We address amblyopia with a personalized approach. Each session is one-on-one (therapist-to-patient), conducted under doctor supervision. Our providers utilize the latest technology and methods, including in-office and home-support virtual reality to develop binocular vision and depth perception, making treatment enjoyable and productive. Furthermore, our treatment is designed for all ages. 

Our advanced treatment includes:

  • In-Office and Home-Support Virtual Reality
  • Intensive Binocular Vision Therapy
  • Visual Processing Development
  • Oculomotor Vision Therapy
  • Eye-Hand Coordination Development
  • Accommodation “Eye Focusing” Therapy

Results

After treatment, our patients improve in their:

  • Visual Acuity (Eyesight)
  • Binocular Vision
  • Depth Perception (3D Vision)
  • Visual Processing Abilities
  • Eye-Hand Coordination
  • Reading Fluency
