TASS Research Paper
Mollie Mary Kathleen Dawson
What is TASS?
TASS stands for Toxic Anterior Segment Syndrome is an acute postoperative inflammatory
reaction in which a noninfectious substance enters the anterior segment and induces toxic
damage to the intraocular tissues. TASS is a post-surgical event after an anterior segment
surgery. At the time of surgery there is no indication is the problem.
What is the cause?
TASS is a rare but serious sterile postoperative inflammatory reaction due to contamination of
noninfectious substance during operation that causes toxic damage in the intraocular tissues.
Unfortunately, TASS usually occurs in a cluster rather than a single case suggesting a common
contamination of patient like series of endophthalmitis. The intense painless inflammation of
the anterior segment typically presents within 24 hours after surgery, in contrast to the longer
presenting time of infectious endophthalmitis.
