| 摘 要： | The spectral VEP in 13 normal subjects(25 eyes),four cases(8eyes)of protanopes and 8 cases(15 eyes)of deuteranopes were tested.Innormal subjects,the shortest latencies of N1,P1,N2 were in 560 nm and thegreatest amplitudes of N1-P1 and P1-N2 were in 560-570 nm,around which thelatencies were delayed and the amplitudes were decreased as the wave-lengthes of stimulative light increased or decreased gradually.The spectralVEP pattern of deuteranopes was similar to the normal subjects.In theprotanopes,the shorter latencies of N1,P1,N2 and greater amplitudes of N1-P1,P1-N2 appeared in 520-530 nm and 570 nm,forming the two-thoughs and two-peaks shapes,with the shortest latencies and the greatest amplitudes in 520-530 nm.There were statistically significant differences of amplitudes and/orlatencies in some wavelengthes between the protanopes and normals and be-tween the deuteranopes and normals.Eye Science 1992;8:126-130.
