Purpose: Tumor vascularity is of diagnostic and prognostic importance. On A-Scan, it is indicated by the presence of a flickering motion. Large tumor vessels can be visualized and examined by color doppler sonography. Due to physical restrictions the low flow in the microcirculation cannot be investigated by the Doppler technique. The aim of our study was the visualization of such small tumor vessels by contrast harmonic imaging (CHI) with a contrast enhancer as a completely new approach in ophthalmology.
