Objectives

To describe the normal ultrasonographic appearance and biometry of the leopard cat’s eye (Prionailurus bengalensis) using B-mode ultrasonography.

Methods

Eight leopard cats (Prionailurus bengalensis) from Chiangmai night safari with no history of previous ophthalmic disease were examined using the portable ultrasound machine with high-frequency curvilinear transducer (10 MHz) in order to describe normal sonographic appearance and biometry measurement. These captive wild cats were premedicated and inducted with xylazine and Zoletil, respectively. The anesthesia was maintained with isoflurane.

Results

The biometric findings were as follows: mean and standard deviation (mean±SD) of the corneal thickness was 0.07±0.0006 cm. Depths of the anterior and posterior chamber were 0.34±0.009 cm. Lens thicknesses were 0.81±0.014 cm. Depths of the vitreous chamber were 0.60±0.009 cm. No significant difference was found between the ocular biometry of the left and right eyes.

Conclusion

This study provides ultrasonographic appearance and baseline information of ocular biometry in leopard cat for further clinical investigations of ocular abnormalities using B-mode ultrasonography.
