Blunt eye trauma: Tear of the iris


The iris is the colored, circular tissue of the eye. It is located behind the cornea and in front of the crystalline lens. It’s main function is to regulate the amount of light that enters the eye.

To maintain good vision it is necessary to preserve the integrity of the iridian diaphragm.

The iris is a delicate vascular tissue which can be affected by ocular trauma.

The clinical manifestations of an ocular trauma with alterations in the iris can be: diplopia (double vision), sensitivity to light and decreased quality of vision.

The tear of the iris can cause bleeding in the anterior chamber of the eye (hyphema) and its treatment is with an iridian reconstructive surgery. This is a complex surgery, so it must be performed by an expert ophthalmologist surgeon.
