[A contribution to the "radial retroiridal pigmentlines" (Vogt) (author's transl)].
In addition to starlike cells, friable pigment and thready remnants of the pupillary membrane, also radial retroiridal pigmentlines which were found on the peripheral anterior capsula of the lens were interpreted to be remnants of the "tunica vasculosa retroiridalis (membrana capsulopupillaris). They seemed to be very rare. An examination of the patients from the Eye-department of the Paracelsus-Institut in Bad Hall/Upper-Austria, showed that "radial retroiridal pigmentlines" could be found in 5% of all examinated patients. In a control examination of 1108 children and juveniles we could see a high proportion of usually described remnants of the pupillary membrane also, but in no case did we find "radial retroiridal pigmentlines". Therefore these pigmentlines do not appear to be hereditary remnants of the pupillary membrane. They seem to be changes of the senium. These pigmentlines which may be caused by a constant friction of the iris on the anterior surface of the lens, we would like to call "Pigmentschleifspuren".
