Chromatic Pattern Visual Evoked Potential among Chinese Children with and without Amblyopia
摘要
Abstract
[Objective] To compare chromatic pattern visual evoked potential (VEP) outcomes among children with healthy eyes, children with refractive amblyopia, and children with anisometropic amblyopia. [Methods] Six types of chromatic pattern VEP tests were applied in the children. [Results] We examined children with healthy eyes (group 1), with refractive amblyopia (group 2), and with anisometropic amblyopia (group 3). There were no significant differences in PI latencies and P1-N2 amplitudes among the six chromatic pattern VEP tests, except that the green-gray test had a longer PI latency than the other tests. There were no significant differences in PI latencies between group 1 and group 2, except for the one based on blue-gray (P = 0.004) and blue-yellow test (P = 0.01). There were no significant differences in P1-N2 amplitudes between group 1 and group 2, except for the one based on red-gray test (P =0.007). There were no significant differences in PI latencies between group 1 and group 3, except for the one based on blue-gray (P =0.02) and blue-yellow test(P = 0.01). There were no significant differences in P1-N2 amplitudes between group 1 and group 3, except for the one based on red-gray test (P = 0.005) and black-white test (P = 0.009). There were no significant differences in PI latencies and P1-N2 amplitudes between group 2 and group 3 (all with P> 0.05). [Conclusions] There are significant differences in PI latencies and P1-N2 amplitudes between amblyopic eyes and healthy eyes, but no differences are noted between refractive amblyopic eyes and anisometropic amblyopic eyes. The chromatic pattern VEP may be useful to differentiate children with amblyopia.关键词
