Ultrasound Biomicroscopy in Pseudophakic Patients with Unexplained Recurrent Hyphema or Vitreous Hemorrhage.

PURPOSE: To describe IOL haptic with iris or ciliary body touch on ultrasound biomicroscopy (UBM) in pseudophakic patients with unexplained recurrent hyphema or vitreous hemorrhage.

METHODS

Retrospective chart review of 10 patients who presented with unexplained recurrent hyphema and or vitreous hemorrhage.

RESULTS

There were eight posterior chamber intraocular lenses (PCIOL) and two sulcus lenses. Four cases had a history of glaucoma; two cases which had a history of trabeculectomy were found to have some bridging vessels along the sclerostomy requiring argon laser gonioplasty. No preceding trauma or retinal pathology was found. UBM revealed haptic-ciliary body or haptic-iris touch in cases with a PCIOL and haptic-iris touch in both sulcus lens cases. One case with a PCIOL did not reveal any haptic-iris or ciliary body touch and instead displacement of the optic temporally, though haptics remained intracapsular.

CONCLUSIONS

UBM is a useful tool to evaluate haptic position in pseudophakic patients with unexplained recurrent hyphema and/or vitreous hemorrhage. This is the largest existing series of patients with this clinical entity reported from a single institution.
