Pseudophakic pupillary block after reverse sulcus intraocular lens implantation: A case report

Reverse sulcus intraocular lens (IOL) implantation can cause serious ophthalmic complications. Even routine ocular examinations can provoke significant consequences. Herein, we present a case of recurrent pupillary capture and pseudophakic pupillary block related to reverse sulcus IOL implantation.

A 44-year-old man developed a pseudophakic pupillary block after pupil dilation aimed at relieving pupillary capture in an undetected reverse position of the sulcus IOL. The pupillary block was successfully treated with 2% pilocarpine and laser peripheral iridotomywas performed to prevent recurrence. The patient experienced recurrent pupillary capture with decreased vision in the affected eye. IOL exchange was the definite treatment resulting in improved vision and proper positioning of the IOL.

When the reverse position of sulcus IOL is detected postoperatively, prophylactic laser peripheral iridotomy should be considered to prevent pupillary block particularly when pupillary capture is present. Pharmacologic pupillary dilation should be performed cautiously. Recurrent pupillary capture is possible and IOL repositioning should be considered to prevent further complications.
