Consecutive toxic anterior segment syndrome in combined phaco-vitrectomy

Toxic anterior segment syndrome (TASS), though rare, has been well documented following anterior segment surgery but not following vitrectomy (Monson et al., J Cataract Refract Surg 18:184–189, 1992 ). It typically presents within 24 h of uncomplicated cataract surgery with minimal or no pain and intense anterior segment inflammation (Monson et al. 1992 ). Various exogenous chemicals have been identified as the cause of TASS (Kutty et al., Cataract Refract Surg, 34:585–590 2008 ; Liu et al., J Cataract Refract Surg 27:1746–1750, 2001 ).
