Abstract:
Objective To explore three-dimensional ultrasonographic features of common ocular diseases. Methods To acquire the data, the free-hand scanning without positioning system was employed in 3 to 5 seconds. Following or after acquisitions, the data were processed and 3D image was reconstructed. Then three-dimensional ultrasonographic features of ocular diseases were characterized. Results 3D images were rendered successfully on 46 eyes of 48 ones. The reconstruction of 3D ultrasonography provided clear stereo images in which shape, dimension, structure, location of retinal detachment, choroidal detachment, vitreous fibrous membrane, lens dislocation, intraocular foreign body and intraocular trauma could be clearly demonstrated. Conclusions 3D ultrasonography needs much shorter scanning time with good space visualization. In the diagnosis of ocular diseases 3D ultrasonic reconstruction can provide more useful information than traditional 2D ultrasonography.
