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.
