In the 1990th, sonographic imaging of the equine eye had developed to a useful diagnostic method. In cases with opacification of the normally translucent media, b-mode-sonography has been the main diagnostic instrument for a long time. Before availability of three-dimensional ultrasound systems, the diagnostician tried to build a three-dimensional picture in his mind out of several two-dimensional images. Improvements in ultrasound technology have enabled the three-dimensional visualisation of many anatomical structures, including the eye structures of the horse The aim of this study was to evaluate the clinical usefulness of three-dimensional ultrasonography on the equine eye. For this purpose, this technique was performed on totally 94 horses. The device for this application was a Siemens SONOLINE® Elegra ultrasonic system with the 5.0 and 6.0 software and a 9 MHz linear-transducer. Data acquisition resulted out of manually linear parallel scans on the upper eyelid. Extirpated eyes had been examined in a water bath. Several pathological situations of the equine eye and partially of the retrobulbar space have been evaluated in this study. This technique offered an excellent imaging method for examination of the complex anatomical ocular structures when ophthalmoscopy and two-dimensional ultrasonography were insufficient.
