Ultrabiomicroscopy 80 MHz of the involved eye. Ultrabiomicroscopy with 80 MHz probe providing a more detailed image of the hyperreflective area found with 50 MHz probe. The 80 MHz probe reveals hyperreflective elements jutting into the anterior chamber from the inner margin of the trabeculectomy opening (arrow). On the lower part there is a magnified image of the trabeculectomy area. The features of the trabeculectomy can be well studied with this technique.
