Abstract

Purpose

In the process of clinical diagnosis and treatment of amblyopia, we have found that the treatment time of this disease was significantly different among different patients. The purpose of this study was to compare the efficacy of binocular vision training (BVT) and Fresnel press-on prism (FPP) on children with esotropia combined with amblyopia.

Methods

From May 2015 to December 2018, a total of 101 children aged 3–9 years with esotropia and amblyopia who were in our hospital were enrolled in this randomized clinical trial. They were randomly divided into combined group (48 cases) and prism group (53 cases): the children in the prism group received FPP treatment, and those in the combined group received the combined treatment of BVT and FPP. The visual acuity, the binocular function and the strabismic therapeutic effects were compared between two groups.

Results

After treatment, the visual acuity in both groups was both significantly improved compared with that before treatment (P = 0.0079). The binocular–monocular function, including synoptophore visual function and the Titmus stereopsis, in both groups was significantly improved compared with those before treatment (P < 0.05), and it was more significant in the combined group compared with the prism group (P < 0.05). The cure rate of strabismus was 87.50% (42/48) and 30.19% (16/53) in the combined group and the prism group, respectively, and there was significant difference between groups (P = 0.0036). The cure time was shortened with the lower of the degree of esotropia.

Conclusion

BVT combined with FPP can effectively promote the recovery of binocular vision in children with esotropia combined with amblyopia, and some children can achieve complete cure of strabismus.
