Abstract
PURPOSE
We report a case of pseudophakic pupillary block after toxic anterior segment syndrome (TASS). CASE SUMMARY: An 84-year-old woman underwent phacoemulsification and intraocular lens implantation in the posterior chamber. Six days after surgery, anterior chamber inflammation was seen. Twenty-five days after surgery, a sudden increase in intraocular pressure (IOP) associated with pupillary block was observed. Despite the use of IOP-lowering medication, the IOP was not controlled. Peripheral laser iridotomy failed. After surgical peripheral iridectomy, IOP decreased significantly and was controlled. CONCLUSIONS: Despite the rarity of TASS combined with pseudophakic pupillary block, clinicians must be aware of this condition in patients showing prolonged inflammatory state and IOP elevation after surgery.
Key Words: Iridectomy;Pseudophakia;Toxic anterior segment syndrome
