Population-based studies on abnormal binocular vision and low literacy are rare. The aim is to determine the prevalence of poor stereoacuity among children with low literacy; to identify the characteristics associated with poor stereoacuity among children with low literacy; and to determine the agreement between poor stereoacuity as measured by graded stereocircles with a computerized assessment.
A total of 490 children attending primary school in the greater Hobart region, Tasmania, aged 7 to 14 years, with literacy results below the 10th percentile for Tasmanian students at grade 3 level of the NAPLAN (National Assessment Program in Literacy and Numeracy) testing completed a vision screen. Poor stereoacuity was defined as more than 100 seconds of arc as measured by Titmus stereocircles.
The prevalence of poor stereoacuity was 16.8% (95% confidence interval [95% CI], 13.6 to 20.4%). Children with poor stereoacuity had a higher frequency of symptom report using the Convergence Insufficiency Symptom Survey. Factors associated with poor stereopsis were prematurity (adjusted odds ratio [AOR], 2.19; 95% CI, 1.09 to 4.42) and bottom shuffling (AOR, 2.39; 95% CI, 1.17 to 4.88). Features associated with poor stereopsis included squint (AOR, 6.05; 95% CI, 3.02 to 12.12), migraine (AOR, 2.25; 95% CI, 1.05 to 4.83), and attention deficit disorder (AOR, 1.92; 95% CI, 1.01 to 3.65).
In this low-literacy sample, one-sixth had low stereoacuity. The associations reported require further investigation.
Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.
I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.
Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.
Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.
Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
