“…The present study, along with others (22-24), does not confirm the reports that IOP significantly changes with age (7,13,28). In our literature review, except for a study on humans (37) and a study on lions (24), none of recent studies (22,23,25,30,36) has reported a significant relationship between the sex variable and IOP. The present study confirms these findings, since no significant difference was found between the mean IOPs obtained with TonoVet ® and Tono-Pen Vet ® for male and female dogs of all ages.…”

“…Similar results were obtained in a study on Anatolian buffaloes (28). On the other hand, in a study using applanation tonometry in Capuchin monkeys no statistically significant difference was found between IOP values of different age groups (23); similar results have also been reported in ferrets (22) and three different herbivorous wildlife species (25).…”

RESUMO.-[Pressão intraocular e teste lacrimal de Schirmer em lobos-guará (Chrysocyon brachyurus).]O objetivo deste estudo foi estabelecer dados de referên-cia sobre a produção lacrimal (STT-1) e pressão intraocular (PIO) em lobos-guará em cativeiro. Foram utilizados 10 lobos-guará, saudáveis e adultos. Os animais foram contidos com cambão e mordaça e mantidos em decúbito lateral esquerdo. O TLS foi realizado no terço médio da pálpebra inferior, durante um minuto. A córnea foi dessensibilizada e a PIO mensurada com tonopen. A média do TLS-1 dos olhos direitos e esquerdo foi 11±5mm/ min, não havendo diferença significativa entre os olhos (p=0,960). A média da PIO dos olhos direitos e esquerdo foi 20±6mmHg, não observando diferença entre os olhos direitos e esquerdos (p=0,836). Média STT-1 foi menor do que, e PIO foi o mesmo que os níveis normais em cães. Não houve diferença estatística na idade dos animais e valores STT-1 e da PIO. No presente trabalho, os níveis médios de guará STT-1 foram mais baixos em comparação com as observadas nos cães, enquanto que a pressão intraocular foi a mesma nos lobos guará como em cães. Devido ao aumento da incidência na prestação de cuidados de emergência para vítimas de lobos-guará atropelamentos e incêndios, determinar os valores de referência dos parâmetros oculares podem melhorar o diagnóstico correto e tratamento de doenças. The purpose of this study was to establish baseline data on lacrimal quantity (STT-1) and intraocular pressure (IOP) in captive maned wolves. Ten healthy adult maned wolves were contained with a snare pole and muzzle and kept in decubitus of the left side. STT-1 measurement was performed on the lateral third of the lower conjunctival sac for one minute. The cornea was desensitized and intraocular pressure was measured with an tonopen. Average STT-1 in both eyes was 11±5mm.min -1 , with no statistical difference between the left and right eye (p=0.960). Average IOP in both eyes was 20±6mmHg, with no statistical difference between the left and right eye (p=0.836). Average STT-1 was lower than, and IOP was the same as normal levels found in dogs. There was no statistical difference in the age of the animals, and STT-1 and IOP values. In the present paper, average maned wolf STT-1 levels were lower compared with those found in dogs, while the IOP was the same in maned wolves as in dogs. Due to the increased incidence in providing emergency care for maned wolf victims of road kill and fires, determination reference values of ocular parameters may improve the correct diagnosis and treatment of the disease.

“…The documentation of intraocular pressure for clinically normal animals is beneficial for diagnosing and monitoring an ocular disease (Ofri et al, 1998). Several methods have been described for measuring IOP in clinical and research situations, including indentation, applanation or rebound techniques (Bengtsson, 1972;Leiva et al, 2006;Jeong et al, 2007).…”

RESUMO Mensuração da pressão intraocular em ovinos, usando tonômetro de aplanaçãoO objetivo deste estudo foi avaliar e estabelecer os valores de pressão intraocular (PIO) média, em ovinos adultos saudáveis, usando a tonometria de aplanação. Foram utilizados no estudo 25 ovinos saudáveis (Ovis aries), da raça Texel, machos ou fêmeas de três anos de idade. Foram realizados exames oftálmicos, incluindo: avaliação dos reflexos pupilares, teste lacrimal de Schirmer, avaliação com lâmpada de fenda e coloração com fluoresceína, em ambos os olhos de todos os animais. Para a realização dos testes oftálmicos, os animais foram contidos pelo mesmo auxiliar, sem pressão na região jugular e as pálpebras foram delicadamente abertas. A PIO foi aferida, utilizando-se o tonômetro de aplanação Tonopen XL, tendo sido todos os exames realizados pelo mesmo examinador. Foram realizadas três avalia- The purpose of this study was to evaluate and establish the mean values of IOP in healthy adult sheep using an applanation tonometer. Information on age, sex, and breed was obtained for all animals included in this study. Twenty five healthy sheep (Ovis aries), of the same breed (Texel), male or female, with three years of age, received an ophthalmic examination in both eyes, including pupillary reflexes, Schirmer tear test, slit lamp biomicroscopy, and fluorescein staining. For all ophthalmic testing, animals were gently physically restrained, with no pressure in the jugular area and the eyelids were carefully open. IOP was measured by applanation tonometry (Tonopen XL). The same examiner performed the tonometry; measurements were taken three times for each eye, and their average was recorded as the IOP of the animal. Statistical analysis was performed using paired t-test and values of P < 0.05 were considered significant. The mean intraocular pressure in the whole group of 50 eyes was of 16.36 +/-2.19 mm Hg. The mean (SD) IOP in the right eye was of 15.96 +/-2.02 mm Hg, while the mean (SD) IOP in the left eye was of 16.76 +/-2.32 mm Hg. Significant differences in IOP were not found between right and left eyes. The applanation tonometer was adequate for measuring the intraocular pressure in sheep. Reference data will assist in diagnosing testing for ophthalmic disease in sheep, as 1 well as promote further studies in this area.
