GENETIC & ACQUIRED HETEROCHROMIA
![Picture](/uploads/2/4/9/4/24949289/1385595804.jpg)
Genetic or Congenital, and Acquired
Heterochromia is taken from an
autosomal trait, meaning the trait
can either be dominant or recessive.
These types of Heterochromia can
be divided into two subgroups,
abnormal iris lighter and abnormal
iris darker. Both types can be a result
of many kinds of diseases which will
be separated and shortly described
below. More information and
specific details can be found upon

Familial Heterochromia is the term used to describe Heterochromia passed on from generations. There is a higher probability for offspring to have heetrochromia if parents, grandparents, or people from past generations have had the condition before.

ABNORMAL IRIS LIGHTERThis type of iris coloration can be inherited or acquired from these syndromes and mutations:

ABNORMAL IRIS DARKER
An iris pigmentation inherited or acquired from conditions listed below:
- Lisch Nodules: A disease that branches off from patients with peripheral neurofibromatosis, the nodules look like yellow or brown sphere-shaped bumps on the surface of the iris.
- Ocular Melanosis: Caused by increased production of melanin from melanocytes in the iris.
- Oculodermal Melanocytosis: Also known as 'Nevus of Ota', is a blue or brown hyperpigmentation on that can occur on the face or eye.
- Pigment Dispersion Syndrome: Takes place when pigment granules fall into the aqueous, a transparent liquid made in the eye. The granules clog up and increase eye pressure. Identified by a visible dark line around the eye or pupil.
- Sturge-Weber Syndrome: Can be distinguished by a visible reddish skin discoloration on one side of the face.
