What is the reason for the generation of fine structures of peaks or multiple peaks?
So far, the reasons haven not been investigated sufficiently. In practice, there are reflections—possibly caused by nystagmus—that are additional to those of the layer reflecting most strongly, the retinal pigmented epithelium (RPE). These reflections are produced by the inner limiting membrane and/or the choroid. This results in additional peaks, most of whose origin can be clarified only by several measurements. In the case of double peaks, they may be produced by both the limiting membrane/RPE and the RPE/choroid. Additional reflections may be produced even by retina ablation. In that case you will probably get an incorrect reading.
