Abstract Details

Purpose:

To report different grades of severity of TASS based on clinical findings

Setting:

Observational study in a Tertiary care hospital at Regional institute of Ophthalmology, Allahabad, India

Methods:

Two episodes of toxic anterior segment syndrome [TASS] were seen in patients who underwent uneventful phacoemulsification with hydrophobic foldable IOL implantation by the same surgeon. 18 patients were operated by centurion vision system(Alcon) and remaining by Catarrhex 3(Oertly instrument AG) machine. Same irrigating fluid was used in all these patients. In three patients, intracameral epinephrine was required. After stromal hydration intra-operative intracameral moxifloxacin was injected in all the patients. Details of the patients were reviewed. Mean age of the patient was 63.8 years. There were 17 males and 18 females.

Results:

A total of 35 patients, with TASS in two episodes, were recorded in our institution. 17 of 35 patients were male and 18 females. Only three patients had diabetes mellitus and none had any other systemic problem. 15 patients had mild degree of toxic anterior segment syndrome, 17 patients presented with moderate degree of TASS. Only three patients presented with severe degree of TASS. Hypopyon was seen in only 3 patients. Severity of corneal oedema, Descemet's folds, aqueous flare, exudates in the pupil, anechoic B scan were the deciding factors in classifying the severity. The response of the treatment was complete and faster in lesser degree of severity. in sever grade several complications were recorded.

Conclusions:

Two episodes of TASS were observed postoperatively in phacoemulsification performed in a tertiary care hospital. We classified them into three groups-mild , moderate and severe based on clinical presentation. Response to treatment was excellent in mild variety and good in moderate variety and not favourable in severe degree. We suggest a classification based on clinical findings which may give us clue to the prognosis of TASS.
