-
摘要:
目的 研究多媒体视功能综合训练对儿童弱视的治疗效果并探讨影响治疗效果的因素。 方法 将3~12岁屈光性弱视患者63例(87眼)随机分为观察组与对照组,观察组予多媒体视功能综合训练,对照组予传统精细目力训练,训练时间均为30min/d,共随访6 个月。分别于治疗前、治疗后1月、3月、6月检查最佳矫正视力(BCVA)、Titmus近立体视、图形视觉诱发电位(pVEP)、Worth四点灯,对比2种训练方法在改善儿童弱视患者单眼视力及双眼视功能方面的差异,并采用相关性分析探讨影响多媒体视功能综合训练治疗效果的因素。 结果 (1)观察组及对照组治疗6月后BCVA均较治疗前提高,观察组提高值更大(P < 0.001)。对轻、中度儿童弱视、3~6岁及7~12岁儿童弱视、屈光不正及屈光参差性儿童弱视患者,观察组BCVA提高值均较对照组大(P < 0.05);(2)观察组Titmus近立体视及眼间抑制改善情况均优于对照组(P < 0.05)。(3)观察组治疗后pVEP P100波振幅(15′频率)较治疗前提高(P < 0.001)。(4)影响多媒体视功能综合训练治疗效果的因素:BCVA提高值与治疗前的LogMAR视力呈正相关,与年龄呈负相关;Titmus近立体视治愈率与治疗前的Titmus近立体视呈正相关,与双眼屈光参差量呈负相关。 结论 (1)多媒体视功能综合训练在提高弱视儿童单眼视力及改善双眼视功能方面疗效均优于传统精细目力训练。(2)影响多媒体视功能综合训练治疗效果的因素:BCVA提高值与患者治疗前的视力、年龄具有相关性;Titmus近立体视治愈率与患者治疗前的Titmus近立体视、双眼屈光参差量具有相关性。 -

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. -
