Determination of eye lens thickness in Rainbow troutsby Ultrasonography

One of the techniques that can be used in Ophthalmic Diagnostic Imaging is ultrasonography. In this technique selected sound waves are send to eye structures and an image can be formed by echo of these waves which interaction with different tissues densities and echogenicies. Several displays for ultrasonography are present. One of these displays is Brightness modulation. In this study, ten lens of eye’s Rainbow trouts (Oncorhyncus mykiss) fshes were measured in anterior-posterior axial by ultrasonography. Total mean of lens was 0.319 ± 0.040 cm. Also mean of right eye lens measurement was 0.317 ± 0.041 cm and mean of left eye lens measurement was 0.321 ± 0.040 cm.In this study mean of right eye lens measurement was not different with mean of left eye lens measurement.
