AIM To demonstrate the ultrasound biomicroscopic features of a ciliary body melanocytoma with extrascleral extension, and a conservative approach in its management. METHOD Observational case reports. Two cases of ciliary body melanocytoma were suspected at presentation, confirmed histologically by biopsy, and subsequently monitored for change by serial ultrasound biomicroscopic imaging. The m...

This paper documents a rare nonprogressive developmental disorder-bilateral circumscribed posterior keratoconus-in a 60-year-old man referred for a cataract surgery. For the first time ultrasound biomicroscopy was used to visualise the local anterior bulging of the posterior corneal surface with concomitant thinning of the stroma. The amount of localized posterior depression, corneal thickness ...

The current study assessed the usefulness of in vivo high frequency ultrasound imaging (ultrasound biomicroscopy, UBM) for dynamic study of the ovarian structures in laboratory rodents. UBM imaging was performed, by using a 40 MHz probe, in 12 C57BL/6J female mice and four Wistars female rats at breeding age and during different reproductive periods. UBM provided outstanding images of both foll...

Early elevated intraocular pressure (IOP) following pars plana vitrectomy is a common complication of vitreoretinal surgery and severe pressure elevation may result in visual loss. To investigate the mechanism of IOP elevation following pars plana vitrectomy, a retrospective review of 119 patients (132 eyes) who had undergone vitreoretinal surgery was performed. Ultrasound biomicroscopy (UBM) w...

CASE REPORT We report a case of a 12-year-old patient who complained about visual disturbances in left eye for 6 months. His visual acuity was 1/0.9, funduscopy in left eye revealed a free-floating cyst in the anterior vitreous. Magnetic resonance showed a low intense image in T1, and B-scan ultrasound confirmed a hypoechogenic cyst of 3.2 × 4.3 mm; ultrasound biomicroscopy revealed a normal ci...
