Resumo: | The objective of this study was to evaluate the intraocular pressure (IOP) of healthy Criollo horses using a rebound tonometer throughout the day. In addition, assessments were made in horses of different ages. Twenty-seven horses, male and female, were divided into three groups by age: Group I (3–5 years old), Group II (6-8 years old), and Group III: (9-16 years old). Ophthalmic examinations were performed using the Schirmer tear test, slit-lamp biomicroscopy, fluorescein test and indirect ophthalmoscopy. Seven measurements of IOP were assessed on the same day (at 6:00 am, 9:00 am, 12:00 am, 3:00 pm, 6:00 pm, 9:00 pm and 00:00 pm). A t-test was used when there were two groups of comparisons and ANOVA was used to detect differences in IOP between measurement times and between age categories. The average IOP was 28.4 ± 3.7 mmHg for all eyes. The mean IOP for Groups I, II and III were 29.2 ± 3.5, 28.4 ± 4.3 and 27.7 ± 3.2 mmHg, respectively. There was no statistically difference between right and left eyes. There was a significant difference between Group I and Group III (P = 0.008). There were no statistically significant differences between measurements recorded at different times of the day (P = 0.560). The IOP was not influenced by the circadian rhythm, but older horses showed reduced IOP. |

Além disso, foram realizadas avaliações em cavalos de diferentes idades. Vinte e sete cavalos, machos ou fêmeas foram divididos em três grupos de acordo com a idade: Grupo I (3 a 5 anos), Grupo II (6 a 8 anos) e Grupo III (9 a 16 anos). O exame oftálmico incluiu teste da lágrima de Schirmer, biomicroscopia com lâmpada de fenda, prova da fluoresceína e oftalmoscopia indireta. Sete medidas de PIO foram realizadas no mesmo dia (às 6h, 9h, 12h, 15h, 18h, 21h e 24h). O teste t foi usado quando havia dois grupos de comparações e a análise de variância (ANOVA) foi usada para detectar diferenças na PIO entre os momentos de medição e entre as categorias de idade. A PIO média foi de 28,4 ± 3,7 mmHg para todos os olhos. A PIO média dos grupos I, II e III foi de 29,2 ± 3,5, 28,4 ± 4,3 e 27,7 ± 3,2 mmHg, respectivamente. Não houve diferença estatística entre os olhos direito e esquerdo. Houve diferença entre o grupo I e o grupo III (P = 0,008). Não houve diferença entre as medidas registradas em diferentes momentos do dia (P = 0,560). A PIO aferida com tonômetro de rebote em cavalos da raça Crioula saudáveis não sofreu influência da hora do dia em que foi realizada, mas foi menor em equinos mais velhos.UEL2021-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionOriginal articleAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4004410.5433/1679-0359.2021v42n3Supl1p2049Semina: Ciências Agrárias; Vol. 42 No. 3Supl1 (2021); 2049-2056Semina: Ciências Agrárias; v. 42 n. 3Supl1 (2021); 2049-20561679-03591676-546Xreponame:Semina.
