Ultrasound Biomicroscopy: Role in Diagnosis of Iris and Ciliary Body Tumours,SAFWAT ELKADY
Abstract
Background & Aim: Ultrasound biomicroscopy (UBM) is an important tool for assessing iris and ciliary body tumours. This study sought to evaluate the role of UBM in the diagnosis of iris and ciliary body tumours.
Methods: Retrospective analysis of data collected from medical records of 10 patients referred to the UBM unit, department of ophthalmology, of Cairo University, for sus-pected iris and ciliary body tumours from January 2003 to July 2006 and 4 patients referred to ocular diagnostic unit in King Abd El-Aziz University Hospital in Jeddah, Saudi Arabia from January 2007 to March 2009.
Results: Fourteen eyes from 14 patients were evaluated, including six ciliary body tumours, six iris naevi, and two iris melanoma using Ultrasound biomicroscope (Model DICON P45 UBM Plus Paradigm instruments). All cases of iris and ciliary body tumours patients were also evaluated with con-ventional A/B-scan. Results of this study revealed that ultra-sound biomicroscopy offers an accurate method to evaluate tumor shape, reflectivity, and local invasion. Ciliary body and peripheral iris involvement by tumours was significantly more frequently observed by UBM than B-scan.
Conclusion: UBM is an indispensable tool for the diagnosis of iris and ciliary body tumours. This study demonstrates the superiority of UBM v conventional B-scan for the precise localization of uveal tumors, especially involving the ciliary body and peripheral iris.
