Abstract

Objective To study the therapeutic effect of multimedia visual function training on amblyopia in children and explore the factors influencing the therapeutic effect. Methods Sixty-three patients with refractive amblyopia aged 3-12 years （87 eyes） were randomly divided into the observation group and the control group. The observation group received multimedia comprehensive visual function training, and the control group received traditional fine visual training for 30 min/d. A total of 6 months of follow-up were performed. Best corrected visual acuity （BCVA）, Titmus near-stereoscopic vision, pVEP and Worth four-point lamp were examined before treatment, 1 month, 3 months and 6 months after treatment, respectively. The differences of monocular visual acuity and binocular visual function in children with amblyopia were compared between the two training methods. Correlation analysis was used to explore the factors influencing the therapeutic effect of multimedia visual function training. Results 1. BCVA in the observation group and the control group increased 6 months after treatment compared with that before treatment, and the increase value in the observation group was greater （P < 0.001）. For mild and moderate amblyopia, amblyopia, ametropia and anisometropia in children aged 3-6 years and 7-12 years, BCVA in observation group was higher than that in control group （P < 0.05）. 2. The improvement of Titmus near stereo vision and interocular inhibition in the observation group was better than that in the control group （P < 0.05）. 3. The amplitude of pVEP P100 wave （15’frequency） in the observation group increased after treatment compared with before treatment （P < 0.001）. 4. Factors influencing the therapeutic effect of multimedia visual function training: BCVA increased value was positively correlated with LogMAR visual acuity before treatment, negatively correlated with age; The cure rate of Titmus near stereo was positively correlated with Titmus near stereo before treatment, but negatively correlated with binocular anisometropia. Conclusions 1. Multimedia comprehensive visual function training is better than traditional fine visual training in improving monocular vision and binocular visual function in amblyopia children. 2. Factors influencing the therapeutic effect of multimedia visual function training: BCVA improvement was correlated with the visual acuity before treatment and age; The cure rate of Titmus near stereo vision was correlated with the Titmus near stereo vision and binocular anisometropia before treatment.
