Lutein treatment minimized deterioration of b-wave/a-wave ratio and improved oscillatory potential (OP) in groups III and IV.
11) Oscillatory potentials may arise on top of the b-wave with increasing stimulus intensity (9) (see Figure 2); these occur due to amacrine cell activity.
For example, oscillatory potentials are sensitive to localised retinal ischaemia and so may be used to assess diabetic retinopathy.
Oscillatory potentials samplitude measured with the addition of OP wavelets was severely diminished.
