Answers
Answer:
Explanation:
Heterochromia is when a person’s irises are different colors. There are a few kinds of heterochromia. Complete heterochromia is when one iris is a different color than the other. When part of one iris is a different color than the rest of it, this is called partial heterochromia. Central heterochromia is when there is an inner ring that is a different color than the outer area of the iris.
But what causes heterochromia and should people with the condition be concerned?
Heterochromia Causes
There are many types and causes of heterochromia. An infant can be born with it or develop it soon after birth. In these cases, it is called congenital heterochromia.
In most cases, children born with heterochromia will experience no other symptoms. They do not have any other problems with their eyes or general health. However, in some cases heterochromia can be a symptom of another condition.
Causes of heterochromia in infants can include:
Benign heterochromia
Horner’s syndrome
Sturge-Weber syndrome
Waardenburg syndrome
Piebaldism
Hirschsprung disease
Bloch-Sulzberger syndrome
von Recklinghausen disease
Bourneville disease
Parry-Romberg syndrome
When a person gets heterochromia later in life, this is called acquired heterochromia.
Causes of acquired heterochromia include:
Eye injury
Bleeding in the eye
Swelling, due to iritis or uveitis
Eye surgery
Fuchs' heterochromic cyclitis
Acquired Horner’s syndrome
Glaucoma and some medications used to treat it
Latisse, a repurposed glaucoma medication used cosmetically to thicken eyelashes
Pigment dispersion syndrome
Ocular melanosis
Posner-Schlossman syndrome
Iris ectropion syndrome
Benign and malignant tumors of the iris
Diabetes mellitus
Central retinal vein occlusion
Chediak-Higashi syndrome
Heterochromia Diagnosis and Treatment
If your infant has heterochromia, he or she should be examined by an ophthalmologist. The ophthalmologist will confirm the appearance of heterochromia and look for any underlying causes. In most cases, there will be no concerning disease or condition causing the eye color variation. However, it is important to rule out these conditions.
If you get heterochromia as an adult or it changes in appearance, see your ophthalmologist. He or she can perform a detailed eye exam to rule out any underlying causes and come up with a treatment plan if necessary.
Treatment for heterochromia focuses on treating any underlying causes for the condition. If there are no other issues with the eyes, no treatment may be needed.
Some people have two different colored irises from a condition called heterochromia. This condition is often caused by injury or trauma to the eye.
Rarely, it may be caused by a birth defect.
