Toxic anterior segment syndrome (TASS) is an uncommon, non-infectious inflammation occurring after any intraocular anterior segment surgical procedure as a result of toxic substances introduced into the eye. Although it usually occurs acutely (within 12-48 hours), late-onset TASS has also been reported.Recognizing and understanding TASS is important for all ophthalmologists. Advances in technology, introduction of novel surgical techniques, and new substances and medications used during intraocular surgery have increased the frequency of this complication.

As a duty of care, to report suspected reactions to new medications, as well as outbreaks of conditions such as TASS, we need to help identify and track cases of TASS. The identification and tracking of cases is a critical means for information to be accurately collected.

Please take few minutes to take this questionnaire . This is to help investigate and manage emerging TASS outbreaks. This will provide assistance for developing TASS awareness and help us to reinforce a preventive strategy. Please take time to report the occurrence of TASS or other infectious disorders.
