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

Abstract

Reference values of tonometry and distances of intraocular structures of Yacare caiman were described. IOP did not correlate with echobiometric measurements in this crocodilian. The ultrasonographic appearance was similar to other domestic and wild species.

The eye of the red‐eared slider turtle: morphologic observations and reference values for selected ophthalmic diagnostic tests

“…Echobiometric evaluation using B‐mode imaging techniques has proved to be a useful tool in ocular examination for wild species, including avian mammal and reptile species . The ocular ultrasonographic evaluation of the slider turtle suggests that the general eye appearance is analogous to other turtles species .…”

“…The ocular ultrasonographic evaluation of the slider turtle suggests that the general eye appearance is analogous to other turtles species . The fact that the ultrasound examination was carried out without the use of chemical restraint should be considered, because even after instillation of anesthetic eye drops, animals could move their eyelids, so the investigator had to wait for the exact moments in which the eyelids were open to capture desired images, unlike what was reported in Yacare Caiman . Despite the difficulty in obtaining the images, due to low resolution of the ultrasound equipment and the extremely small eye size of these turtles, the researchers believe that B‐mode ultrasonographic measurements presented in this study are useful for clinical evaluation and can provide reliable information about the intraocular anatomy of the slider turtle eye.…”

Determination of baseline values for routine ophthalmic tests in bearded capuchin (Sapajus libidinosus)

“…Over the years, normal baseline values have been investigated and reported for the Schirmer tear test (STT), intraocular pressure (IOP), and anatomical eye measurements. Descriptions of the ocular microbiota and characterizations of the conjunctival cells in some species of wild and exotic animals have also been performed . However, baseline data on these parameters have not yet been reported for the bearded capuchin ( S. libidinosus ).…”

Aspectos ultrassonográficos, biometria e dopplerfluxometria ocular do bugio ruivo (Alouatta fusca)

“…Os pontos de referência utilizados neste estudo para mensuração das diferentes distâncias na biometria ocular dos bugios ruivos foram semelhantes àqueles citados por estudo de Ribeiro et al (2009) e Ruiz et al (2015), realizados em caprinos Saanen e jacarés-do-Pantanal, respectivamente; incluindo a profundidade da câmara anterior (D1), a espessura da lente (D2), a profundidade da câmara vítrea (D3) e o comprimento axial do bulbo ocular (D4).…”
