Ultrasound biomicroscopy of chronic hypotony after cataract extraction.

摘要

Ultrasound biomicroscopy was performed with a UBM 840 (Zeiss-Humphrey) equipped with a 50 MHz probe on a patient with chronic hypotony 1 year after cataract surgery by phacoemulsification with intraocular lens implantation in the capsular bag. This sonographic technique, which provides high-resolution imaging of the anterior segment, showed aqueous humor leakage through the former scleral tunnel incision. Ultrasound biomicroscopy helped detect this patient's postoperative complication and is a good tool for diagnostic procedures in patients with chronic hypotony.
