Analysis of oscillatory potentials of flash electroretinogram in frequency domain and time domain in retinal vein occlusion

摘要

Conclusion: Some parameters of Ops in frequency domain and time domain are abnormal in branch retinal vein occlusion and in central retinal vein occlusion, which is more marked in the latter. Purpose: To analyse the parameters of frequency domain and time domain of the Ops in Branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). Methods: Ops from 9 eyes of BRVO, 9 eyes of CRVO and 40 normal control eyes were test- Ed. The frequency spectra of the Ops were derived through Fast Fourier Transform (FFT).
