Toxic anterior-segment syndrome (TASS)
Clinical Ophthalmology, 2014
Purpose: To evaluate the clinical findings and courses of five patients who developed toxic anterior-segment syndrome (TASS) after cataract surgery and investigate the cause. Materials and methods: In May 2010, on the same day, ten patients were operated on by the same surgeon. Five of these patients developed TASS postoperatively. Results: Patients had blurred-vision complaints on the first day after the operation, but no pain. They had different degrees of diffuse corneal edema, anterior-chamber reaction, fibrin, hypopyon, iris atrophies, and dilated pupils. Their vision decreased significantly, and their intraocular pressures increased. Both anti-inflammatory and antiglaucomatous therapies were commenced. Corneal edema and inflammation resolved in three cases; however, penetrating keratoplasty was needed for two cases and additional trabeculectomy was needed for one case. Although full investigations were undertaken at all steps, we could not find the causative agent. Conclusion: TASS is a preventable complication of anterior-segment surgery. Recognition of TASS, differentiating it from endophthalmitis, and starting treatment immediately is important. Controlling all steps in surgery, cleaning and sterilization of the instruments, and training nurses and other operation teams will help us in the prevention of TASS.

Toxic anterior segment syndrome is acute inflammatory reaction caused by a noninfectious substance that enters the anterior segment, resulting in extracellular damage with necrosis and apoptosis during an immune response. We have the report of a case of toxic anterior segment syndrome (TASS), in which the authors seek to emphasize the most common causes of the appearance of these syndrome. They point out the care that must be taken in the process of sterilization of surgical material, in addition to reviewing the best conduct when faced with these cases. In conclusion, it was noted that the main focus should be on prevention, as treatment only seeks to suppress the secondary inflammatory response. Treatment in cases of toxic anterior segment syndrome (TASS) consists of intense instillation of topical steroids with strict follow-up and control of late complications such as glaucoma.

Material and Methods: TASS occurring after uneventful coaxial phaco during May/June 2008 in eye department, Combined Military Hospital Kharian, were analyzed retrospectively in this case series. Clinical features, response to treatment and possible causes were checked during the outbreak (including intracamerally given drugs, irrigating solutions, intraocular lenses and washing/ sterilization techniques for instruments) and measures taken to prevent further cases. Follow up continued till Feb 2009.
Toxic anterior segment syndrome after cataract surgery: the implications for nursing
Objective: To describe the characteristics of the toxic anterior segment syndrome (TASS) and its implications for nursing actions. Method: It is a literature review through research in the MEDLINE (Medical Literature Analysis and Retrieval System Online) and LILACS (Latin American and Caribbean Center on Health Sciences Information) databases. Results: TASS is an acute ocular inflammatory reaction after ophthalmic surgeries, mainly cataract surgery. The clinical signs in the first 12 hours after the surgery include corneal edema, presence of cells in the anterior chamber, increased intraocular pressure, and irregular pupil. The main causes are related to noninfectious substances introduced into the patient’s eye by products used during surgery or due to failures in cleaning and sterilization of surgical instruments. Conclusion: The implications for nursing consist of preventive measures, staff training, orienting the patients, and active epidemiological surveillance aimed at the ear...
