Purpose: To report a case with pseudophakic pupillary block after lens removal with posterior chamber intraocular lens (PC-IOL), which is rarely found. And the benefits of anterior segment imaging (UBM) in helping diagnosis

Method: A Case report

Result: A 30-year-old Thai female presented with sudden right eye pain for 2 weeks. She had undergone uncomplicated cataract surgery on her right side for 6 years. The initial intraocular pressure (IOP) was 60 mmHg. The slit-lamp examination on the right eye revealed diffused marked corneal edema with un-uniformly shallow anterior chamber (AC) and non-reactive corectopia. The diagnosis was pseudophakic pupillary block with 360-degree posterior synechiae accommodated by anterior segment ultrasound biomicroscope (UBM). The symptoms disappeared after doing a laser peripheral iridotomy. Four weeks after laser treatment, the IOP was well controlled with only medical treatment.

Conclusion: The diagnosis of angle closure in the pseudophakic eye was challenging because it is infrequent. However, with meticulous clinical examination and assistance of anterior segment ultrasound biomicroscope (UBM) could facilitate the diagnosis and guide the suitable treatment.

Conflicts of Interest: None.
