The causes of hypo- and hyperchromic heterochromia were analysed in 94 patients. The hypochromic forms were the commonest, especially the Fuchs-Herrenschwandt heterochromia, and heterochromia simplex. Also after degenerative diseases and accidents appears almost exclusively hypochromic heterochromia. Causes of hyperchromic heterochromia (siderosis, melanosis, wart-iris) were in the minority. Finally a heterogenous group of pseudoheterochromiae were more closely examined. This group seemed to be mainly hypochromic but in 2 rare cases the pseudoheterochromia was cuased by a brown dystrophy of the repeatedly inflamed cornea, probably associated with repeated fluorescien-staining of large corneal erosions.
对94例患者的浅色和深色异色症病因进行了分析。浅色型最为常见，尤其是富克斯 - 赫伦施万特异色症和单纯性异色症。在退行性疾病和事故后几乎仅出现浅色异色症。深色异色症（铁锈沉着症、黑素沉着症、虹膜疣）的病因占少数。最后，对一组异质性的假性异色症进行了更仔细的检查。这组似乎主要是浅色的，但在2例罕见病例中，假性异色症是由反复发炎的角膜棕色营养不良引起的，可能与大的角膜糜烂反复荧光素染色有关。
