Abstract/Introduction

Purpose: To evaluate factors predicting resolution of amblyopia and the time course of improvement in VA in children 3 to 7 years old with anisometropic amblyopia treated with spectacles alone.

 

Design: Prospective, noncomparative intervention.

Methods: Measurement of corrected amblyopic logMAR visual acuity (VA) in newly diagnosed children at four-weekly intervals until VA stabilized or amblyopia resolved. The time course of improvement in VA and the factors related to amblyopia resolution were assessed.


Conclusion/Results

Results: Sixty children with a mean age of 5.3 years and mean anisometropia of 2.95 diopters (D) were included. Amblyopia improved by 2 or more logMAR lines in 56 patients (93%) and resolved in 27 patients (45%), with a mean improvement in VA of 0.38 logMAR. The improvement in VA in the amblyopic eye was considerable at four to 12 weeks then reached a plateau, after which it improved only slowly. Resolution of amblyopia was related to better initial VA (0.2 to 0.6 logMAR) and lesser amounts of anisometropia (<4 D). The time to resolution ranged from four to 40 weeks, but no patient with residual amblyopia showed an improvement in VA of more than 0.1 logMAR over four consecutive visits.

Conclusions: With spectacle correction alone, 3- to 7-year-old children with previously untreated anisometropic amblyopia achieved approximately four-line improvement and resolved nearly in half. The nearly two-month plateau periods during improvement of VA should be noticed. After four months with no improvement in VA, occlusion therapy or atropine penalization may be considered.


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 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!!!
