Assessment of the Lens Anterior–Posterior Diameter as Compared with the Eye Globe by Ultrasonography in Rabbit

Abstract

Objective- Assessment of the lens anterior-posterior (AP) diameter as compared with the eye globe by ultrasonography in rabbit. Design- Descriptive study. Animals- 120 male and female rabbits, two months to four years old, and weighting between 300 to 1500gr. Procedures- 2D ultrasonography of the eyes was performed and AP diameter of the eyes and lens were measured using Sonosite Titan Ultrasound equipment. Results- In the obtained 2D images, the eye parts were showed a distinct anechogenic to hypoechogenic structure. Details of the eyes compartments were observed by 2D transducers. Anterior and posterior lens capsules and optic discs were hyperechogenic. The average AP diameter of lenses was 0.6175 cm and of the eye globes was 1.4789 cm. Conclusion and Clinical Relevance- The 2D ultrasonography give useful images for teaching and diagnostic purposes such as eye globe and lens lesions or diameter changes. The average of lens AP diameter in comparison with the globe was 0.4165.
