Toxic Anterior Segment Syndrome

From Wikipedia, the free encyclopedia

Toxic Anterior Segment Syndrome (TASS) is an eye disease caused by toxins entering and causing inflammation in the anterior segment of the eye, located between the lens and the cornea. It is often cured with anti-inflammatory treatment, but in severe cases TASS can lead to torn or detached retinas, a form of glaucoma and vision loss.

Since the anterior segment of the eye is the area targeted in cataract surgeries, TASS can be caused by washed surgical instruments that have traces of packaging chemicals or detergents on them.
