A- and B-modes echobiometry in cataractous and noncataractous eyes of English Cocker Spaniel dogs

Abstract

A-and B-modes ultrasonographic changes in the thickness of various structures of the eyeball in male and female English Cocker Spaniel dogs with and without nondiabetic cataracts were evaluated. Sixteen dogs with cataracts (32 eyes) and seven normal dogs (14 eyes) older than eight years were selected. Aand B-modes ultrasonography was performed with a 10MHz transducer. Data was statistically evaluated by one way ANOVA. Mean and standard deviations of various ocular structures for dogs with and without cataracts were, respectively, anterior chamber: 3.041±0.

Intraocular pressure, ultrasonographic and echobiometric findings of juvenile Yacare caiman (Caiman yacare) eye

“…Similar to what has been described in mammals, gender did not seem to influence the echobiometric values of ocular structures. As reported in tortoises and in the American alligator, IOP did not differ between genders in the Yacare caiman.…”

“…Ultrasonographic appearance of the eyes of Yacare caiman was similar to the eyes of other wild/exotic and domestic species . It has been reported that scleral ossicles of birds generate a lateral acoustic shadow during ultrasonography, which was not observed in eyes of Yacare caiman, probably because young individuals were studied.…”

“…A‐mode ultrasonography is described as an accurate tool to measure structures of the eye . Notwithstanding, in this study and in others, B‐mode ultrasonography is more readily accessible than A‐mode ultrasound, in addition to allowing the evaluation of intraocular anatomy and measurement of intraocular distances at the same time .…”

Biometric, B-mode and color Doppler ultrasound assessment of eyes in healthy dogs

“…The means for the lens thickness and length were 0.72±0.05cm for the right eye and 0.73±0.04cm for the left eye; and 1.22±0.10cm for the right eye and 1.22±0.11cm for the left eye, respectively, and the values were very close when both eyes were compared (Table 1). Silva et al (2010) assessed seven dogs of the English Cocker Spaniel breed and observed mean lens thickness of 7.14±0.35mm for the right eye and 7.19±0.57mm for the left eye that presented very close values compared to the present study. In this same study, biometric assessment was also made of the eyeball of dogs with cataract and it was verified that there was no statistical difference between the animals in the control group and the group with cataracts.…”

Ocular echobiometry and head measurements in Jersey cattle from different age groups

“…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). The iris and the ciliary body in the studied cattle were thick and irregular when compared to those of other species such as dogs (Squarzoni, 2011) and humans (Lorente‐Ramos et al., 2012; Silva et al., 2011).…”
