Biometria ultra-sonográfica bidimensional em tempo real do globo ocular de cães

Sixty ocular globes of 30 health dogs were utilized to perform a real-time ultrasonic biometry, with the objective of getting distance measurement of intra-ocular structures. The measurements were taken from cross-sectional sagital image with the dogs in esternal recumbence, and manual containment, with the use of topical ocular anesthetic vehicle applied in the cornea. A 7.5 MHz transducer of a mechanical sector scanner without flotation pad was used. The measure averages were 3.9 ± 0.7mm (D1) distance between the midcornea to anterior capsule; 6.1 ± 1.2mm (D2) lens thickness; 10.5 ± 1.0mm (D3) lens diameter; 9.1 ± 0.4mm (D4) vitreous chamber depth; and 18.8 ± 0.9mm (D5) midcornea to retinal distance. Significant difference was observed among the right and left eyes only in D1.
