In the News (Thu 24 Dec 09)

  
  heterochromia
This is the condition in which one eye differs in color from the other (technically, heterochromia iridum).
Heterochromia may also develop later in childhood or adulthood as a result of injury to the eye, bleeding within the eye, inflammation within the eye, eye tumors, or other conditions.
Heterochromia also can refer to the condition in which a portion of an iris differs in color from the remainder (heterochromia iridis).

  Heterochromia - Wikipedia, the free encyclopedia
Heterochromia (also known as a heterochromia iridis or heterochromia iridium) is an ocular condition in which one iris is a different color from the other (complete heterochromia), or where part of one iris is a different color from the remainder (partial heterochromia or sectoral heterochromia).
Although a distinction is frequently made between heterochromia that affects an eye completely or only partially, it is often classified as either congenital or acquired with mention as to whether the affected iris or portion of the iris is darker or lighter.
Heterochromia that is congenital is usually inherited as an autosomal dominant trait.

Heterochromia iridium (two different-colored eyes within a single individual) and heterochromia iridis (a variety of color within a single iris) are relatively rare in humans and result from increased or decreased pigmentation of the iris.
Most cases are isolated and sporadic, conceivably resulting from an alteration in the expression of the above-mentioned genes (and those we have yet to find) within the cells of the entire iris or even a particular section.
There are a few well-known syndromes of which heterochromia iridis is a striking feature.
