What is the Iris?
The iris is the colored part of your eye. It may be blue, green, black, or brown. Its color comes from melanin and just like your fingerprint, the color, texture, and pattern of your iris is unique.
Its main function is to control the amount or level of light that enters into your eye. It is also responsible for controlling the diameter and size of your pupils.
The iris is divided into two zones namely pupillary and ciliary. The inner part of your iris is in the pupillary zone while the remaining part can be found on the ciliary zone.
In terms of layers, the iris has two layers- stroma and pigmented epithelial cells.
What Conditions Affects the Iris?
Just like the cornea, the iris may also be affected and damaged. There are several iris disorders that you may experience like iritis, aniridia, iris coloboma, and eye trauma with damage to the iris.
What are the Symptoms of Iris Disorders?
The symptoms of iris vary depending on the circumstances. In Iritis, both eyes may be affected and one suffering from it will experience decreased vision, pain, or light sensitivity.
If you have aniridia, your iris is underdeveloped and this may occur during pregnancy. On the other hand, when your iris contains a hole, it is possible that you have iris coloboma. Aniridia and iris coloboma both resulted from a genetic defect.
How are Iris Disorders Treated?
Seeking medical care is important to treat the abovementioned disorders. In treating iritis, it is best to regularly visit your eye doctor and use prescription medications exactly and properly as prescribed. Also, it would be beneficial to wear dark glasses just in case the light worsens your eye pain.
