To determine the prevalence, subtypes, and associated risk factors for intermittent exotropia (IXT) in preschool children aged 3 to 6 years in eastern China.
A population-based study including 5831 preschool children aged 3 to 6 years was conducted from 2011 to 2012 in Yuhua District, Nanjing, China, using an age-stratified random sampling procedure. Clinical examinations including ocular alignment, ocular motility, visual acuity, prism cover test, cycloplegia refraction, stereopsis screening, slitlamp examination, and fundus examination were performed by trained ophthalmologists and optometrists. Intermittent exotropia was defined as an acquired intermittent exodeviation of at least 10 prism diopters in an otherwise healthy child following the classification recommended by the National Eye Institute.
The overall prevalence of IXT in this population was 3.24% (95% confidence interval, 2.79 to 3.69%), with no age (p = 0.19) and sex (p = 0.89) differences. Among 166 children with IXT, the “basic type” was the most common type of IXT (74.7%), the “divergence excess” was the second (19.9%), whereas the “convergence weakness” was the rarest (5.4%). In multivariate analysis adjusting for age, sex, and other confounders, the presence of IXT was only associated with a history of hypoxia at birth (odds ratio, 4.41; 95% confidence interval, 2.47 to 7.86).
Intermittent exotropia affected approximately 1 in 30 Chinese preschool-aged children in eastern China, indicating a relatively higher burden of this pediatric eye condition in the world’s most populous country. The presence of IXT was strongly associated with a history of hypoxia at birth.
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.
