RESUMEN
OBJECTIVE:To investigate the clinical efficacy of levodopa combined with comprehensive therapy for ametropic amblyopia children and teenagers and its effeets on pattern visual evoked potential(P-VEP)and visual function. METHODS:70 pa-tients(80 eyes)with ametropic amblyopia were randomly divided into observation group(35 cases,40 eyes)and control group(35 cases,38 eyes). Control group received comprehensive therapy as wearing correctional glasses,occlusion therapy and visual stimu-lation training;observation group additionally received levodopa 0.125(d1-3)-0.25 g/time,bid,on the basis of control group for 6 months. Therapeutic efficacy,P-VEP,Visual sensitivity and visual function were compared between two groups,and the occur-rence of ADR was recorded. RESULTS:The effective rate of observation group(92.50%)was significantly higher than that of con-trol group(76.32%),with statistical significance(P0.05). CONCLUSIONS:Levodopa combined with comprehensive therapy can improve the function of visual central neurons,and improve visual acuity and binocular stereo vision functions so as to improve therapy efficacy.
