Ultrasound biomicroscopy as a tool for detecting and localizing occult foreign bodies after ocular trauma

摘要: Abstract Objective To show the utility of ultrasound biomicroscopy (UBM) in imaging small ocular foreign bodies anterior segment. Design Retrospective case series. Participants Twelve eyes 12 consecutive patients evaluated emergency department or referred to specialty services at 1 institution between August 1994 and November 1997 were examined. Intervention Ocular was performed. Main outcome measures Detection localization an body measured. Results An intraocular superficial detected by UBM 9 (75%) eyes. The classified as corneal two eyes, subconjunctival two, intrascleral three, not visible ophthalmic physical examination seven nine with a confirmed body. In remaining used determine depth three body, computed tomography and/or contact B-scan ultrasonography obtained failed Six nonmetallic. Conclusions Clinical detection after trauma can be hindered size, haziness optical media, poor patient cooperation, hidden location. Ultrasound is valuable adjunct evaluation suspected bodies, especially cases involving small, nonmetallic objects.
