“…The present study was conducted with Jersey cattle, which were chosen for their phenotypic homogeneity, in addition to being considered remarkable animals for milk production, feed conversion, precocity, Ocular structures such as the cornea, anterior chamber, anterior and posterior lens capsules, vitreous chamber and posterior wall presented similar echogenicity and echotexture to those of other mammals (Assadnassab & Fartashvand, 2013;Beserra et al, 2009;Ekesten & Torrång, 1995;Ferreira et al, 2014;Gonçalves et al, 2009;Kassab, 2012;Laus et al, 2013;McMullen & Gilger, 2006;Mirshahi et al, 2014;Plummer et al, 2003;Potter et al, 2008;Ribeiro et al, 2009; Silva et al, 2010; Squarzoni, 2011; Toni et al, 2013;Tuntivanich et al, 2007) and wild animals (Bapodra et al, 2010;Harris et al, 2008;Hernández-Guerra et al, 2007;Montiani-Ferreira et al, 2008;Rajaei et al, 2016;Ruiz et al, 2015;Squarzoni et al, 2010;Toni et al, 2010).

Routine ophthalmologic examination with B-mode ultrasound has become essential for evaluating the eye and biometry in different species, such as dogs (Beserra et al, 2009;Ekesten & Torrång, 1995;Silva et al, 2010;Squarzoni, 2011;Toni et al, 2013;Tuntivanich et al, 2007), cats (Ferreira et al, 2014;Gonçalves et al, 2009;Mirshahi et al, 2014), goats (Ribeiro et al, 2009), cattle (Potter et al, 2008), buffaloes (Assadnassab & Fartashvand, 2013;Kassab, 2012), horses (McMullen & Gilger, 2006;Plummer et al, 2003), donkeys (Laus et al, 2013), rabbits (Toni et al, 2010), Asian elephants (Bapodra et al, 2010), ferrets (Hernández-Guerra et al, 2007), guinea pigs (Rajaei et al, 2016), capybaras (Montiani-Ferreira et al, 2008), owls (Harris et al, 2008;Squarzoni et al, 2010), penguins (Bliss et al, 2015) and alligators (Ruiz et al, 2015).…”

“…Ocular biometry correlated with head measurements provides important information for preparing ocular prostheses for ophthalmic surgeries such as enucleations and those performed due to bilateral congenital malformations (Ferreira et al, 2014;Larsen, 1979;Mirshahi et al, 2014;Squarzoni, 2011). Head measurements and echobiometry of different breeds can also help with the early diagnosis of ocular diseases, in addition to allowing them to be monitored (Toni et al, 2013).…”

A longitudinal study was conducted to identify the morphological development of eyes and head of Jersey cattle at different ages. A total of 48 healthy Jersey cattle, 1 to 58 months of age, were included in the study. Ophthalmologic examinations were performed to identify healthy cattle to form the age groups: GI (1‐ to 11‐month‐old), GII (16‐ to 24‐month‐old) and GIII (25‐ to 58‐month‐old). The animals were physically restrained and examined by transcorneal ultrasound of both eyes; the axial length (AxL), corneal thickness (CO), lenticular thickness (L), depth of the anterior (AC) and vitreous (VC) chambers were evaluated. The cranial measurements obtained included the total, cranial, and nasal lengths and widths. Subsequently, the cephalic index (CI) was calculated. The AxL (GI: 2.83 cm; GII: 3.16 cm; GIII: 3.24 cm), AC (GI: 0.44 cm; GII: 0.53 cm; GIII: 0.53 cm), L (GI: 0.88 cm; GII: 1.01 cm; GIII: 1.04 cm) and VC (GI: 1.44 cm; GII: 1.55 cm; GIII: 1.59 cm) increased (p ≤ .001) according to age, but the CO (GI: 0.07 cm; GII: 0.08 cm; GIII: 0.08 cm) (p > .05) did not. The total length (GI: 30.83 cm; GII: 43.29 cm; GIII: 44.15 cm), cranial length (GI: 18.11 cm; GII: 23.82 cm; GIII: 22.69 cm), nasal length (GI: 12.72 cm; GII: 19.47 cm; GIII: 21.46 cm) and nasal width (GI: 26.22 cm; GII: 33.82 cm; GIII: 34.00 cm) increased (p < .001), and the CI (GI: 85.66 cm; GII: 78.15 cm; GIII: 77.02 cm) decreased (p < .001). The AxL correlated positively (p < .001) with the cranial length and width and negatively with the CI (p > .05). The ocular biometry of Jersey cattle correlates with their cranial measurements at different ages. With increasing age, the eyes and the head grow, establishing growth curves similar to those of other mammals.

“…Ferreira et al (2014) demonstrated the inefficiency of frequencies between 8 and 9MHz when measuring cornea thickness in adult cats. Transductors with frequency higher than 20MHz give greater image definition and penetration power (from 20 to 80μm), allowing the visualization and measurement of images of the anterior eye segment, including the cornea in dogs and cats (Bentley et al 2003).…”

B-scan ultrasonography is an important diagnostic tool that allows characterization of internal organ anatomy and, when complemented by Doppler ultrasound, allows vascular hemodynamic assessment, increasing the diagnostic accuracy. Thus, the aim of the present study was the B-scan ultrasound characterization and measurement of the eyeball segments and assessment of the external ophthalmic artery by color and pulsed Doppler. Sixty eyeballs were assessed from 30 dogs of different breeds using an 8.5MHz microconvex transductor. First, biometry was performed by B-scan of the following segments: axial length (M1), anterior chamber depth (M2), lens thickness (M3), lens length (M4), vitreous chamber depth (M5), optical disc length (M6) and optic nerve diameter (M7). Colored Doppler identified the external ophthalmic article and pulsed Doppler assessed its flow, and the following were measured: systolic peak velocity (VPS), final diastolic velocity (VDF), resistivity index (IR) and pulse index (IP). No statistical difference was observed for the biometric values of the eye segments between the right and left eyes (p>0.05). The vitreous chamber depth (M5) was shown to be the biometric variable with greatest bilateral symmetry, varying from 0.79 to 0.87cm and 0.78 to 0.86cm for the right and left eye, respectively. The ophthalmic artery was visualized over the optic nerve towards the eyeball, with flow stained red. There was no significant statistical difference between the Doppler velocimetric values for the ophthalmic artery between the right and left eye of the animals assessed (p>0.05). The mean resistivity index (RI) showed average values equal to 0.63±0.03, bilaterally. The mean base velocity was 17.50cm/s and 18.18cm/s at the systolic peak and 6.21cm/s and 6.68cm/s at the end of the diastole, for the right and left eyes respectively. The anatomic, biometric and hemodynamic characterization using the ultrasound B-scan and the Doppler modalities permitted the ultrasonographic and Doppler velocimetric assessment of the eyeball components in dogs of different breeds, and it can be used in ophthalmic clinical routine to identify eye pathologies.

The purpose of this paper is to determine the ocular echobiometry and investigate its correlation with cranial and body morphometric parameters in 50 adult Shih Tzu dogs. The echobiometric measurements of the anterior chamber (AC), vitreous chamber (VC), lens axial thickness (LTA), transverse lens thickness (LTT), and axial length of the eyeball (ALE) were obtained by two-dimensional ultrasonography. Morphometric measurements of bizygomatic distance (BDIST), frontal-occipital distance (FOD), withers height (WH), thoracic circumference (TC), and body length (BL) were also obtained. The mean of the AC depth was 2.83±0.50mm, the VC was 9.18±0.54mm, the LTA was 6.42±0.32mm and the LTT was 9.17±1.18mm, while the mean of the ALE was 18.82±0.66mm. There was no correlation between ocular echobiometric variables and cranial and body morphometric variables in adult dogs of the Shih Tzu breed, as well as no significant difference of these variables when considering gender and age of the dogs (p ≥ 0.05).
