Chuck2* Abstract Background: Toxic anterior segment syndrome (TASS) can be a rare complication of anterior segment surgery. By Rosario Díez, Lourdes Jordano and César Hita. Toxic anterior segment syndrome (TASS) is an acute postoperative inflammatory reaction in which a noninfectious substance enters the anterior segment and induces toxic damage to the intraocular tissues. In the past this condition was known by many names, such as postoperative uveitis and sterile endophthalmitis. After uncomplicated cataract surgery, toxic anterior segment may occur in the early postoperative period, which is treated successfully with steroids. Most patients with toxic anterior segment syndrome will develop symptoms within 12 to 24 hours of the surgery. Although there are well known risk factors for postoperative endophthalmitis, some prophylaxis strategies remain controversial.

The TASS subsided without complications in all cases after intensive topical steroid treatment. The aetiology of sterile endophthalmitis, independently of the administered drug, remains uncertain and a multifactorial origin cannot be discarded. More studies are needed to understand the multifactorial risk factors affecting the etiopathogenesis of this syndrome. Toxic Anterior Segment Syndrome (TASS) is an acute post- ... endophthalmitis.
