ABSTRACT

Toxic anterior segment syndrome (TASS) caused by non-infectious agents is a sterile inflammation which occurs after anterior segment surgery and results in toxic damage to the intraocular tissues. Occurring within 12-48 hours after surgery, the most common symptoms and signs are blurred vision, corneal edema and inflammation. There are many agents accused in the etiology such as: irrigation fluids, improper sterilization of surgical instruments, ocular medications, and intraocular lens. Postoperative endophthalmitis is important in the differential diagnosis. In this article, a case of TASS seen after phacoemulsification surgery is discussed in terms of diagnosis, differential diagnosis, and treatment modality.
