Abstract Purpose:To report ultrasound tissue harmonic imaging as compared with conventional B-mode ultrasonography in ophthalmology.

Cases and Methods:Conventional B-mode ultrasonography and the tissue harmonic imaging were performed on 6 patients. Two patients were examined by contact method and the remaining four, by the immersion technique. The obtained images were evaluated by three certified ultrasonographers.

Results:Clearer images were obtained by the tissue harmonic imaging than by the conventional B-mode ultrasonography. The results of the evaluation of the three doctors showed that the tissue harmonic imaging was significantly better than conventional B-mode ultrasonography in penetration, detail, and total image quality. In cases done by the immersion technique, artefacts were greatly reduced, which contributed to a better resolution.

Conclusion:Tissue harmonic imaging proved to be superior to conventional B-mode ultrasonography in image quality. It is a promising imaging technique in ophthalmology as well, especially when used by the immersion technique.
