Abstract
Objective To study the characteristics of Pattern Reversal VisualEvoked Potentials (PRVEP) in children with accommodative esotropic amblyopia. Methods Multiple channel VEP elicited by monocular full field and half field stimulation were recorded in 32 children with accommodative esotropic amblyopia and 24 normal controls. Results (1) Full field stimulation: In esotropic eyes, the latencies and the amplitudes of the P wave recoreed from electrose No. 1～14 were significantly prolonged and reduced compared with those in normal controls (P＜0.05 or 0.01) The waves of VEP recorede from the electrodes on the left side were irregular compared with those on the right side. (2) Half field stimulation: In esotropic eyes, the latencies of the P wave recorded from the corresponidng electrodes of stimulation were significantly prolonged compared with those in normal controls (P＜0.01); The latencies of P wave evoked through nasal retina were more significantly prolonged than that through temporal retina (P＜0.01). But those asymmetries were not observed in non-esotropic eyes of this group. Conclusions The VEP recordings from the external electrodes of Oz may be affected by various conditions when those were evoked by full field stimulation. There may be VEP naso-temporal asymmetries of half field stimulation in the esotropic eyes of accommodative esotropic amblyopia.关键词
