Ocular Dominance Stability and Reading Skill: A Controversial Relationship

Abstract/Introduction

Purpose

Evidence is mixed concerning the relationship between stability of ocular dominance and reading deficits. Contrasting results may be due to the use of different tests of dominance, different samples of readers, and different scoring methods. The aim of this study was to investigate the relationship among ocular dominance, general visual abilities, and reading performance, and to evaluate the consistency and reliability of different tests of ocular dominance and the effects of different types of eye dominance scoring.

 

Methods

In a group of young adults, we measured: (a) main optometric parameters; (b) reading time and accuracy; and (c) ocular dominance in two sighting and four motor tests. Dominance was determined using different scoring methods (relative, absolute, and binary scores).


Conclusion/Results

Results

All dominance tests showed good levels of internal reliability. Sighting tests were consistent regardless of the scoring method, and all participants had stable dominance. Three of four motor tests were moderately consistent when dominance was measured with relative scores but not when it was measured with absolute or binary scores. No relationship was found between stability of dominance and reading performance, regardless of the type of test or scoring method. No systematic pattern of correlation was found between binocular vision variables and dominance measures.

 

Conclusions

Choosing the type of motor test to measure ocular dominance is crucial, because the level of consistency among tests is low to moderate. Furthermore, motor tests were not correlated with reading performances. Present results suggest caution when trying to link reading difficulties with specific profiles of ocular dominance.


Testimonials


Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy is well worth the expense, time and effort. Our son had a hard time focusing handwriting neatly. After vision therapy Seth could complete a task in half the time it previously took his abilities to focus and improved greatly and so did his handwriting.

Also, he was better at listening. As a parent you wanted learning to be fun for our son and vision therapy made this possible.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
