Clinical Course of Accommodative Esotropia

To report the clinical course of patients having accommodative esotropia and to determine whether the strabismus resolves during the adolescent years.



Patients diagnosed with accommodative esotropia from 1983 to 1991 were recalled to the clinic for re-examination. For all patients, the clinical records indicated that the esotropia had begun in early childhood and was controllable at some time during the follow-up period with plus power single vision glasses and/or bifocals. Re-examination included assessment of patient history, visual acuity, ocular alignment, versions, sensory fusion, and refractive error. The ocular alignment status with and without any current plus single vision and/or bifocal correction, and the refractive error at recall, were compared to the same findings taken at the patient's initial clinic visit. These findings were compared to determine whether the accommodative esotropia had resolved, improved, remained the same, or increased in amount.



Thirty-nine patients participated in the study. At the time of recall their average age and follow-up period were 16.8 and 9.5 years, respectively. Before treatment, the mean eso deviation was 14.5δ at distance and 21.6δat near. At recall, 15 patients used single vision glasses, 9 used glasses with bifocals, 11 used contact lenses, and 4 patients used no optical correction. Five patients (12.8%) had best corrected acuity in one eye of 20/30 or poorer. Twenty patients (57.1%) were not strabismic with their current refractive correction, whereas 15 patients (42.8%) continued to be esotropic (intermittent or constant) at distance and/or near. When assessing ocular alignment without the current plus power correction, 26 patients (82%) were esotropic and 4 patients (15.6%) were heterophoric. The mean deviation without the optical correction was 18.6δ at distance and 19δ at near. Of the 4 patients presenting without an optical correction, 3 were esotropic at distance and/or near and 1 patient was heterophoric. Six patients (15.3%) also had inferior oblique overaction, 2 which occurred with superior oblique palsy. Thirty-three patients (86.8%) fused the Worth dot test at distance and/or near, and 35 patients (89.7%) had stereopsis (mean, 84 sec arc). The mean spherical equivalent refractive error changed for the group from 2.77 D hyperopia at the initial evaluation to 1.95 D hyperopia at recall (mean refractive shift=-0.08 D/year).



Accommodative esotropia persists for most patients into adolescence and early adulthood. These patients need to be carefully monitored during this period because most do not outgrow their hyperopia and some can again become esotropic.


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!!!
