A beautiful anomaly.


They say the eyes speak volumes about your beauty. They
carry a stream of emotions for you to dive into and reflect the colours of your
personality. So, while most people use contact lenses to beautify their eyes,
some people are blessed in disguise of an anomaly that makes them both
beautiful and unique. In medical terms we call it as heterochromia. لعبه البوكر لعبه البوكر

 What is

Heterochromia is a condition that describes colour
variation in iris determined by the production and concentration of melanin
pigment. Melanin pigment gives eye its colour. The lesser the pigment produced
in the eye; the lighter is the colour of the iris (blue). Normally both irises
have the same colour. In heterochromia, the iris may be hypopigmented or
hyperpigmented as compared to the other.

In complete heterochromia, one iris is completely different
in colour than the other. Sectoral or partial heterochromia describes a condition
when a single iris has different colour combinations.

What causes this uniqueness?

Most of the cases result from chromosomal mutations
such as mutations in the genes that affect melanin distribution at 8-HTP
pathway. Some acquired cases have also been reported following iritis and
anterior uveitis. Whatever the cause maybe, this anomaly is most commonly seen
in cats and dogs and is very rare in humans. Sturge-weber syndrome and
Waardenburg syndrome may also result in heterochromia.

Rarity and treatment:

Speaking of how rare it can be in humans, the incidence of
congenital heterochromia is 6 in every 1000, and this too hardly noticeable.
Treatment involves iris transplant surgery (highly controversial due to
cosmetic reasons). Besides, who would want to let go of the opportunity to look
beautiful and unique?
(as most of the times it does not cause any problems)
