Testes oftalmológicos e poder dióptrico da lente intraocular em lobo guará (Chrysocyon brachyurus - Illinger, 1815)

Barros, Rodrigo. January 2018 (has links)
Orientador: Cláudia Valéria Seullner Brandão / Resumo: Este trabalho tem como objetivo descrever valores oftalmológicos, determinar o poder dióptrico da lente intraocular (LIO), além de comparar os olhos considerando a lateralidade e sexo nesta espécie e avaliar a hipótese que os valores são similares com o cão. O lobo guará (Chrysocyon brachyurus) encontra-se na lista vermelha de espécies em extinção do The International Union for Conservation of Nature (IUCN), de animais em quase ameaça. As principais causas são a caça indiscriminada e atropelamentos. A espécie possui hábitos noturnos e crepusculares, o que torna a visão um dos seus sentidos mais importantes. Diante disso, a pesquisa avaliou 13 lobos guarás (26 olhos), hígidos, com idade superior a um ano, machos e fêmeas com peso entre 25 e 30kg. Foram realizados os seguintes testes oftalmológicos: teste lacrimal de Schirmer (TLS), estesiometria, tonometria e paquimetria. Adicionalmente, foi realizada a ultrassonografia modo A (US-A), ceratometria e a medida da distância limbo-limbo; e o calculo da dioptria lenticular. Foram obtidos os seguintes valores médios para os testes oftalmológicos: TLS 19,15±3,58mm/min; estesiometria 0,96±0,31mm; tonometria 13,96±4,75mmHg; paquimetria 528,50±55,13µm; distância limbo-limbo 18,08±1,32mm; comprimento axial 21,04±0,55mm e profundidade de câmara anterior 4,63±0,33mm; e cetarometria média 37,21±1,32D. Referente às fórmulas: SRK/T 34,04±1,66D; Hoffer Q 36,31±1,83D; Holladay I 35,42±1,88D, Haigis 42,19±2,29D e Holladay II 35,00±1,65D. Foram d...

The maned wolf (Chrysocyon brachyurus) is in the red list of endangered species of the International Union for Conservation of Nature (IUCN), a near-threatened animal. The main causes are indiscriminate hunting and trampling. The species has nocturnal and crepuscular habits, which makes the vision one of its most important senses. In this research were evaluated 13 maned wolfs (26 eyes), healthy, captive wolves, aged from 1 to 8 years, four males and nine females with weight between 25 and 30kg. The following ophthalmological tests were performed: Schirmer's lachrymal test (SLT), esthesiometry, tonometry and pachymetry. Additionally, ultrasound mode A, keratometry and measurement of limbo-limbo distance were performed; and the calculation of lenticular diopter. Values of the ophthalmological tests were obtained: SLT 19,15±3,58mm/min; esthesiometry 0,96±0,31mm; tonometry 13,96±4,75mmHg; pachymetry 528,50±55,13μm; limbo-limbo distance 18,08±1,32mm; axial length 21,04±0,55mm and anterior chamber depht 4,63±0,33mm. Cetarometry average 37,21±1,32D. The formulas: SRK/T 34,04±1,66D; Hoffer Q 36,31±1,83D; Holladay I 35,42±1,88D, Haigis 42,19±2,29D and Holladay II 35,00±1,65D. The ophthalmologic variables and diopt... (Complete abstract click electronic access below) / Doutor
