Abstract

Ultrasound biomicroscopy (UBM) is a valuable diagnostic modality for imaging anterior ocular structures. Its utility has been well studied in anterior segment, lenticular, and pars plicata pathologies. However, imaging of the pars plana has been seldom described. We present the case of a 66-year-old woman referred for vitreous hemorrhage after expulsive cannula dislodgement into the posterior segment during wound hydration at the end of cataract surgery. B-scan ultrasonography initially detected a very anterior abnormality, but the resolution was insufficient for accurate diagnosis. Subsequent UBM clearly showed rupture of the pars plana and a mild cyclodialysis cleft. To our knowledge, this is the first report of a pars plana rupture detected by ultrasound, which expands the diagnostic capacities and indications for UBM.
