According to a retrospective study published in BMC Ophthalmology.

“In this study, we evaluated the effectiveness of vision therapy as a treatment for amblyopia and compared this binocular approach to conventional treatments in children with amblyopia aged 7-10 years,” Yi-Ching Hsieh, BMattending physician in the department of ophthalmology at China Medical University Hospital in Taiwan, and colleagues wrote.

From April 2016 to November 2019, researchers recruited 36 children with unilateral refractive amblyopia and divided them into two groups to evaluate vision therapy as a treatment option.

Nineteen children were assigned to the case group and their treatment included binocular vision therapy for 1 hour per week for 3 months, wearing glasses and using an eye patch on their weaker eye for 4 at 6 hours a day. The control group included 17 children who received the same treatment without vision therapy.

Hour-long vision therapy sessions included anti-suppression, binocular vision-based training, and behavioral training. The researchers measured visual acuity at baseline, every 3 months for 9 months, and 3 months after treatment ended.

The mean visual acuity of the case group at baseline was 0.39 ± 0.24 logMAR, which improved to 0.10 ± 0.23 logMAR at the end of treatment (P P = 0.015).

Eight children in the control group did not measure any improvement, compared to only one child in the case group. Three months after the end of treatment, the children in the case group experienced no regression in visual acuity.

Hsieh and colleagues also found that the combined treatment of vision therapy, optical correction, and patch resulted in a shorter treatment period: an average of 3.63 months to achieve the best visual acuity for the case group, versus 4.41 months for the control group.

“Visual therapy combined with optical correction and patching is a more effective treatment than optical correction and patching alone in children 7 to 10 years of age with unilateral amblyopia,” the researchers wrote. “The treatment results not only in greater vision gain, but also in shorter treatment time as part of the mechanism of binocular vision and perceptual learning.”
