Assessing the Contribution of the Oscillatory Potentials to the Genesis of the Photopic ERG with the Discrete Wavelet Transform

Figure 3

(a) %OP contribution to the photopic ERG response obtained from a normal subject and patients with diabetic retinopathy (DR) (b) and CRVO (c). All photopic ERG responses were evoked to the 0.64 log cd·s·m⁻² stimulus. Sections of the scalogram that were not considered in the %OPs computation were shaded to facilitate comparison. The descriptors (20b, 40b, 80ops, and 160ops) that were used to compute the %OPs are localized on each scalogram. The %OPs is shown at the top of each DWT scalogram.
