A 55-year-old woman presented with sudden diminution of vision in her left eye following trauma with her own finger. Examination revealed a firm subconjunctival swelling superiorly with aphakia and hypotony. Lens spike was absent on B-scan. Ultrasonic biomicroscopy showed thickened conjunctiva, a subconjunctival mass lesion with an underlying uveoscleral discontinuity. A surgical repair was performed with successful restoration of globe integrity. This case demonstrates that ultrasonic biomicroscopy may reveal the site and the extent of occult scleral rupture and help in precise surgical planning.
