摘要
目的:探讨弱视儿童治疗前后立体视觉及P-VEP的变化。方法:在我院门诊确诊的弱视儿童41例68眼,其中男17例29眼,女24例39眼,年龄4～16(平均8.29±3.05)岁,按照弱视类型分为斜视性弱视组4例7眼,屈光参差性弱视组11例11眼,屈光不正性弱视组26例50眼。弱视治疗内容包括激光治疗、CAM训练、红光闪烁、立体视训练、电脑中频脉冲治疗。治疗前后分别对患者进行裸眼视力、最佳矫正视力、图形视觉诱发电位(patternvisualevokedpotential,P-VEP)、同时视、融合视及立体视检测。结果:弱视患儿治疗前,同时视、融合视、立体视的异常率分别为51.2%,51.2%,80.5%,其中以立体视受损最为常见。弱视治疗后,视力增进2行或2行以上者21眼(31%),基本治愈43眼(63%),无效4眼(6%),总有效率为94%。屈光不正性弱视疗效优于斜视性弱视或屈光参差性弱视。同时视、融合视、立体视功能正常者比例均增高。图形视觉诱发电位中P100波潜伏期缩短(P<0.05)。结论:弱视患儿经积极的弱视治疗后,患儿的视力及立体视觉均可得到提高,P100波潜伏期缩短。
AIM：To discuss the change of stereopsis and pattern visual evoked potential （P-VEP） in amblyopia before and after the treatment. METHODS： According to the type of amblyopia, forty-one patients （68 eyes） were divided into strabismic group （7 eyes of 4 patients）, anisometropic group （11 eyes of 11 patients） and ametropic group （50 eyes of 26 patients）. Uncorrected visual acuity, best-corrected visual acuity, P-VEP, simultaneous perception, range of fusion and stereoacuity were examined before and after the treatment, which including laser therapy, CAM training, red light flashing, stereoacurity training and IF-pulse treatment of computer. RESULTS： Before the treatment, the abnormal rate of simultaneous perception and range of fusion were both 51.2%, while stereoacuity was 80.5%, which means stereoacuity was damaged most commonly in amblyopia. Visual acuity was improved after the treatment： cure rate was 63%; progress rate was 31%; total efficiency rate was 94%.There was a statistical difference between ametropic group and strabismic or anisometropic group in term of efficiency rate. Stereopsis was significantly promoted （P0.01） and the P100 latency was significantly shortened （P0.05）. CONCLUSION： After the treatment of amblyopia, visual acuity and stereopsis were both promoted and the P100 latency was shortened.
