HETEROCHROMIA IRIDIS

TYPES 

There are three types of heterochromia. These include:

• Heterochromia iridis. Heterochromia iridis, also known as complete heterochromia, is a condition where one iris has a completely different color from the other. 
• Heterochromia iridum. Heterochromia iridum, otherwise known as segmental heterochromia, refers to the condition where the iris is composed of different colors.
• Central heterochromia. Central heterochromia occurs when the outer or surrounding layer of your iris has a different color or pigment from the rest of it.

SYMPTOMS

Melanin is a pigment that gives the iris its color. It’s what appears to give them their blue, green, brown, and hazel colors. Hence, fewer melanin results in lighter eye color, while darker eyes result from more melanin. However, you may notice the color difference with certain lighting conditions or when looking at them up close.

Heterochromia, however, does not come with any other symptoms other than having different colored irises. The difference of eye color between the eyes or within one eye is typically the only sign or symptom.

DIAGNOSIS

If you have noticed the difference or change of color in one eye or both, it would be better to seek a consultation with an ophthalmologist. This is because while heterochromia may not come with any risks, it may also be a sign for underlying medical conditions.

If it is indeed caused by another underlying condition, your doctor might conduct a blood exam or genetic tests to know the cause. A full eye exam is also done to track the time of you experiencing heterochromia.

TREATMENT

There is no need to treat heterochromia. However, if it is caused by any underlying conditions, the treatment will be focused on the said condition. 

On the other hand, if you want to have both of your eyes in the same colors, wearing contact lenses is an option.
