Resumo: A biometric analysis of the eye globe and its components from Nellore cattle was carried out in 121 normal eye globes obtained from slaughtered animals aged two to three years at the city of Itaperuna-RJ, Brazil. Twenty macroscopic measurements were made ??in each globe and its structures. The globes showed optical axis averaging 33.27 ± 1.55 mm, equatorial diameter of 38.07 ± 1.70 mm and an estimated volume of 24.07 ± 3.51 mL. There was a moderate positive correlation (r = 0.723, p <0.0001) between the optical axis and the equatorial diameter of the eye globe in this breed. The cornea of Nellore animals showed vertical and horizontal axes comparatively smaller than European breeds described in literature, but the proportion between the height and width of the cornea remained similar. The lens also presented smaller dimensions compared to European animals. This study provides useful data for future clinical investigations of ocular abnormalities in Nellore cattle as well as for research in comparative anatomy.KEYWORDS: Nellore cattle, ocular biometry, veterinary anatomy.

Para tal, analisaram-se 121 bulbos oculares de animais abatidos com idade entre dois a três anos em um estabelecimento no município de Itaperuna- RJ, Brasil. Vinte medições macroscópicas foram feitas nos bulbos oculares e suas estruturas. Os bulbos apresentaram eixo óptico medindo 33,27 ± 1,55 mm, diâmetro equatorial de 38,07 ± 1,70 mm e volume estimado de 24,07 ± 3,51 mL. Houve correlação moderadamente positiva (r = 0,723, p < 0,0001) entre o eixo óptico e o diâmetro do bulbo ocular na raça. A córnea de bovinos da raça Nelore demonstrou eixos vertical e horizontal comparativamente menores do que a das raças europeias citadas na literatura, porém a proporção entre a altura e a largura da córnea se manteve semelhante. A lente também apresentou dimensões menores em comparação a outras raças. Este estudo fornece dados úteis para futuras investigações clínicas das anormalidades oculares na raça Nelore bem como para pesquisas em anatomia comparada.PALAVRAS-CHAVE: anatomia veterinária, biometria ocular, gado Nelore.  Universidade Federal de Goiás2014-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/1977510.5216/cab.v15i2.19775Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 15 No. 2 (2014); 207-212Ciência Animal Brasileira / Brazilian Animal Science; v. 15 n. 2 (2014); 207-2121809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/19775/16723https://revistas.ufg.br/vet/article/view/19775/16724Corrêa, Lanna Beatriz Neves SilvaSanta´Anna Junior, Leny PereiraSouza Junior, Paulo deinfo:eu-repo/semantics/openAccess2014-06-30T13:37:48Zoai:ojs.revistas.ufg.br:article/19775Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:55.440105Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
