ABOUT CONVERGENCE INSUFFICIENCY AND EXCESS
WHAT IS CONVERGENCE INSUFFICIENCY?
Convergence insufficiency is a condition that in many cases is undetected due to the fact that it is generally not detected with a regular eye exam. It is a condition where the eyes have issues teaming, tending to converge outwards instead. This leads to a variety of symptoms such as eye strain, headaches, inability focusing on close vision tasks, issues with tracking or seeing letters move, and double vision. In many cases the person will compensate by covering or closing one eye when doing near tasks. The effects of Convergence insufficiency are severe with the most common issues being hand eye co-ordination, posture, difficulty focusing on close work. Clinical trials have shown overwhelming success with using vision therapy to correct for convergence insufficiency.
WHAT IS CONVERGENCE EXCESS?
Convergence excess is the condition where the eyes tend to turn towards each other. The most common name for this condition is Strabismus. Esotropia is a form of Strabismus where one eye turns inward. Esphoria is the term used for milder cases of convergence excess. The most common symptoms are headaches, eye fatigue, and difficulty focusing for a longer period of time. For cases of Esphoria and Strabismus a vision therapy program is considered the best course of treatment. For more severe forms of Convergence Excess such as Esotropia and Amblyopia patching or special lenses may be recommended.
WHY TREAT EARLY?
Many types of Convergence related issues are better treated at an earlier age. The ideal age for treating Amblyopia and Esotropia is considered 5-6 years of age. In addition to the benefits of efficacy of treatment, there are many side benefits of treating convergence issues earlier.
- The effects of untreated convergence insufficiency and excess is that your child will have a harder time focusing, reading, which in many cases will lead to a general frustration with learning and reading.
- In situations where the eye turns inwards or outwards in a noticeable manner, there are severe social pressure on the child.

What is Amblyopia and Strabismus?
Amblyopia (Lazy Eye)
Amblyopia, also known as “lazy eye”, is the lack of normal visual development in an eye, despite the eye being healthy. If left untreated, it can cause legal blindness in the affected eye.
What causes amblyopia?
The most common cause of amblyopia is strabismus (intermittent or constant misalignment of the eyes). Another common cause is a significant difference in the refractive errors (nearsightedness, farsightedness and/or astigmatism) in the two eyes.
Strabismus is the intermittent or constant misalignment of the eyes and is commonly called cross eyed. The good news is that Strabismus and Amblyopia can be treated, however it’s important to correct amblyopia as early as possible, before the brain ignores vision in the affected eye.
Amblyopia and Strabismus Treatment
Amblyopia and strabismus (lazy eye or cross eye) are treated at a young age using one of the following methods depending on the age, maturity and severity of the condition. In many cases our Optometrist, Dr. Schwartz, will recommend a combination of the following.
- Vision Therapy: Customized training to teach your eyes to work together
- Prism Glasses: Special lenses that correct for the combined vision created by both eyes
- Patching: Patching of the stronger eye to build up the weaker ignored eye
- 3D games and virtual patching, some products allow for virtual patching where the 3D goggles favor one eye over the other thereby strengthening the weaker eye.
