Absence of iris - what does this mean
Absence of iris, also known as aniridia, is an eye condition caused by a genetic mutation that results in the partial or complete absence of the iris, the colored part of the eye. this can lead to decreased vision, increased sensitivity to light, and a higher risk of developing certain eye conditions such as glaucoma.
What happens during the disease - absence of iris
Absence of the iris is caused by a congenital disorder known as aniridia, which is a genetic disorder that affects the development of the iris in the eye. it is caused by a mutation of the pax6 gene, which is responsible for the development of the eyes during embryogenesis. this mutation can lead to the abnormal development of the iris, resulting in partial or complete absence of the iris. this can cause a range of vision problems, including decreased vision, light sensitivity, and difficulty with night vision.
Absence of iris - Prevention
The best way to prevent absence of the iris is to avoid any trauma to the eye, such as a blow to the eye or a chemical burn. additionally, regular eye exams can help to detect any potential issues with the iris early on, allowing for prompt medical treatment.
