Aquired Heterochromia - Sectoral - Commonly known as sectoral or partial heterochromia iridius, this condition affects only a portion of the abnormal iris (shown). In this illustration, the iris is considered hypochromic in comparison to the normal iris and can be caused by Siderosis in acquired cases.
Aquired Heterochromia - Central - In central heterochromia iridius, there is differing pigmentation located around the pupillary zone of the abnormal iris (shown). When the affected iris is hyperchromic in comparison to the normal iris, it could be due to Iridocorneal Endothelial Syndrome, use of certain eye drops, or iron deposition within the ocular tissue either from a penetrating injury or blunt trauma to the eye.
Aquired Heterochromia - Complete - Most common of the three, heterochromia iridium is a condition where one iris is a different color than the other. In this particular illustration, the affected iris (shown) is hypochromic, in which the iris tissue exhibits a lack of pigmentation in comparison to the normal iris. This can be caused by Fuchs’ heterochromic iridocyclitis, Acquired Horner’s syndrome, Neoplasm, or Chronic iritis.
