Late onset lens particle glaucoma as a consequence of spontaneous dislocation of an intraocular lens in pseudoexfoliation syndrome.

Purpose: To report acute onset lens particle glaucoma associated with pseudoexfoliation-related dislocation of an intraocular lens implant 12 years after cataract surgery.

Methods: Case report.

Results: An 80-year-old woman presented with acute onset of left eye pain that was associated with white fleck-like particles circulating in the anterior chamber and an intraocular pressure of 48 mm Hg. The posterior chamber intraocular lens within the capsular bag was positioned more posteriorly to the iris plane than usual, and pseudoexfoliative material was present on the lens capsule and the zonules. Anterior chamber aspirate confirmed the presence of lens cortical fibers.

Conclusion: Spontaneous dislocation of the posterior chamber intraocular lens in patients with pseudoexfoliation syndrome several years after cataract surgery may liberate lens cortical material, causing lens particle glaucoma.
