Abstract: | The B mode ultrasonographic images of bottlenose dolphin (Tursiops truncatus) eyes from cadavers and live animals were measured and compared with physical measurements of cadaver eyes. The average sonographic diameters of the cadaver eyes were 2.34 cm × 2.0 cm (cranial--caudal × dorsal-ventral) with an internal circumference of 7.11 cm. Physical measurements of these diameters were not significantly different (2.51 cm × 2.2 cm). Ultrasound measurements of cadaver eye tunic thickness were significantly larger than physical measurements of the same eyes. In live dolphins, eye diameters measured sonographically were not significantly different (2.55 cm × 2.32 cm) than either ultrasound or physical measurements. The optical axis diameter was 1.80 cm, and the circumference was 7.30 cm in live dolphins. Comparisons of circumference showed no significant difference between cadaver and live dolphin eye measurements. B mode ultrasonographic ocular morphometry may be useful once baseline values have been established. |
