4D数字化弱视斜视矫治系统对远视性屈光不正性及屈光参差性弱视的疗效观察

目的:评估4D数字化弱视斜视矫治系统对远视性屈光不正性及远视性屈光参差性弱视儿童的疗效。方法:招募3~9岁远视性屈光不正性及远视性屈光参差性弱视患者48例(其中远视性屈光不正性弱视18例36眼,远视性屈光参差性弱视30例30眼),所有患者排除其他眼病,在屈光矫正、合理遮盖的基础上接受4D数字化弱视斜视矫治系统的训练。初期训练以提高视力为主,视力达0.6以上者加上脱抑制训练及双眼视功能训练。比较训练前、后的视力及双眼立体视变化情况。结果:远视性屈光不正性弱视患者共18例36眼,其中轻度弱视组13眼,中度弱视组19眼,重度弱视组4眼。远视性屈光参差性弱视患者共30例30眼,根据弱视程度分为轻度弱视组5眼,中度弱视组13眼,重度弱视组12眼。治疗60次后视力均有明显提高。治疗60次后立体视有明显提高,且与屈光度无关(P>0.05),与初始视力及治疗后视力均呈正相关(P<0.05),与屈光参差量呈正相关(P<0.05)。结论:4D数字化弱视斜视矫治系统联合传统的弱视治疗方法能有效提高3~9岁远视性屈光不正性弱视和远视性屈光参差性弱视儿童的视力并改善其双眼视功能。

Effect of S4D computer treatment in children with hyperopic anisometropia and hyperopic anisometropia

AIM: To evaluate the effect of stereoscopic 4D(S4D)technology as a visual training system in children with hyperopic amblyopia and hyperopic anisometropic amblyopia.

METHODS: Totally 48 patients aged 3-9 years with hyperopic amblyopia and hyperopic anisometropic amblyopia were recruited, including 18 hyperopic amblyopia(36 eyes)and 30 hyperopic anisometropic amblyopia(30 eyes). All patients excluded other eye diseases and received S4D technology training on the basis of refractive correction and reasonable covering. The initial training was mainly to improve visual acuity. Those with visual acuity above 0.6 were treated with disinhibition training and binocular visual function training. The changes of visual acuity and binocular stereopsis before and after training were compared.

RESULTS: The 18 patients(36 eyes)with hyperopic amblyopia were divided into mild amblyopia group(n=13), moderate amblyopia group(n=19)and severe amblyopia group(n=4). 30 patients(30 eyes)with hyperopic anisometropic amblyopia were divided into mild amblyopia group(n=5), moderate amblyopia group(n=13)and severe amblyopia group(n=12). The visual acuity was significantly improved after 60 times of treatment. After 60 times of treatment, stereopsis was significantly improved, which had nothing to do with the initial diopter(P>0.05), but positively correlated with the visual acuity initially and finally(P<0.05), and positively correlated with the amount of anisometropia(P<0.05).

CONCLUSION: S4D technology training combined with traditional treatment can effectively improve the visual acuity and binocular function of 3-9 years old children with anisometropic amblyopia and hyperopic anisometropic amblyopia.
