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

Table 2

Ophthalmological and electrophysiological findings of the end-stage patient cohort included in this study. Patient number, age, visual acuity, visual field findings, rod- and cone-mediated ERG responses, diagnosis, %OPs values, and associated -scores are each indicated in individual columns. The %OPs contributing to the cone ERG response and associated -scores are shown in the last two columns, respectively. The critical -score was set to a value of 1.645 and therefore any value > 56.6 + (i.e., 60.7) is considered to be significant. LP: light perception; flat: extinguished ERG; RP: retinitis pigmentosa.
