目的应用VEP检测方法观察内斜视眼的鼻侧视网膜抑制现象在弱视治疗后的改变。方法对34例完全屈光性调节性内斜视弱视儿童治疗前及治疗3、6、9个月后进行一般视功能及多导图形VEP检测,并与24例正常儿童进行比较。结果内斜视眼:治疗前,半视野刺激VEP鼻侧视网膜潜伏期较颞侧延长存在非常显著性差异(P<0.01),全视野刺激VEP地形图偏向患眼鼻侧。治疗后:视力及视功能均改善,鼻颞侧视网膜潜伏期差值较治疗前缩短存在显著性差异(<0.05),VEP地形图偏态分布有所恢复。结论内斜弱视眼的鼻侧视网膜抑P制现象随弱视治疗进展存在逐渐恢复趋势。
Objective To observe the changes of nasal retina inhibition in esotropia after amblyopia treatment by VEP detection. Methods 34 cases of amblyopic children with complete reflex esotropia were treated with general visual function and polygraph VEP before treatment and 3, 6, and 9 months after treatment, and compared with 24 normal children. Results In esotropia, there was a significant difference (P <0.01) between the half visual field stimulation and the temporal extension of the retina latency of the VEP nasal retina before and after treatment. After treatment, the visual acuity and visual function were all improved. There was a significant difference (P <0.05) between the difference in latency of nasal and temporal retina compared with that before treatment. The skewed distribution of VEP topographic map was recovered. Conclusions The phenomenon of suppression of P in the nasal retina of anterior oblique amblyopia tends to recover gradually with the progress of amblyopia treatment.
