Purpose
This report describes an unusual case of delayed toxic anterior segment syndrome (TASS) following cataract surgery and its treatment.
Case
summary: A 55-year-old male patient underwent uneventful phacoemulsification with implantation of an intraocular lens (IOL) and eye patching with ophthalmic ointment at the end of the operation. At 1 week postoperatively, a significant increase in the number of anterior chamber inflammatory cells and multiple gray-white deposits on the anterior surface of IOL were noted. All laboratory tests to exclude infectious endophthalmitis were negative. Under the presumptive diagnosis of delayed TASS, an intensive topical steroid was administered. The number of anterior chamber cells decreased; however, the patient complained of blurry vision and multiple whitish precipitates remained on the IOL. Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser treatment was performed to disrupt and remove the precipitates. The deposits were easily and clearly removed using the laser, and there was no recurrence during a 2-year follow-up.
Conclusion
Delayed-onset TASS can manifest as lumpy white inflammatory cell deposits that cannot be controlled with topical steroids. However, Nd:YAG laser treatment can effectively remove inflammatory precipitates.
