UBM shows sclerotomy site changes

TOKYO — Ultrasound biomicroscopy is helpful in detecting abnormalities around ganciclovir implants. The imaging technology is valuable in assessing changes in the sclerotomy sites for these sustained-release drug delivery devices, according to a small study.

Researchers here used ultrasound biomicroscopy (UBM) to examine eight eyes of six patients who had ganciclovir implants. Exams were performed 1 to 26 months postop. The implant contour was successfully viewed using a UBM with high reflectivity. Three implants had deviated anteriorly and four were deviated posteriorly. The remaining six implants were at the appropriate position. Thick membranes extending from sclerotomy sites to the ora serrata were found at two sites in two eyes.

The study is published in the August issue of British Journal of Ophthalmology.
