Resumo
A catarata é uma opacidade parcial ou total das fibras da lente e/ou da sua cápsula.
Comum nos cães, constitui uma das principais causas de cegueira nesta espécie. Actualmente,
a facoemulsificação é a técnica cirúrgica indicada para o seu tratamento.
Este estudo teve como objectivo caracterizar cataratas observadas numa população
canina e determinar o estímulo iatotrópico, visão consciente e indicação cirúrgica. A amostra
foi constituída por 161 olhos de cães com cataratas diagnosticadas num hospital de referência
de Lisboa, entre Março de 2012 e Março de 2015.
Observou-se que as cataratas ocorrem sobretudo em cães geriátricos, apresentando
distribuição ocular predominantemente bilateral, representando 80% (128/161) da amostra
com localizações anatómicas variadas, sendo o envolvimento da totalidade da lente a mais
observada com 35,4% (57/161). A etiologia mais prevalente, desconhecida, constituiu 32,9%
(53/161) da amostra e o estádio de desenvolvimento revelou-se, sobretudo, incipiente com
57,8% (93/161). Relativamente ao estímulo iatotrópico, o desconhecido foi o mais frequente
com 58,4% (94/161); já a visão demonstrou-se maioritariamente preservada com 67,9%
(108/159). O tratamento cirúrgico de cataratas foi contra-indicado em 62,1% (100/161) da
amostra.
Este trabalho realça a importância da sensibilização para o diagnóstico precoce das
cataratas, a fim de preservar capacidade visual e bem-estar animal.
A cataract is a partial or total opacity of the lens fibers and/or their capsule. Common in dogs, it is one of the main causes of blindness in the species. Currently, phacoemulsification is the surgical technique indicated for its treatment. The purpose of this study was to characterize cataracts observed in a canine population and determine the iatotropic stimulus, conscious vision and surgical indication. The sample consisted of 161 eyes of dogs with cataracts diagnosed in a reference hospital in Lisbon between March 2012 and March 2015. It was observed that cataracts occur mainly in geriatric dogs, presenting predominantly bilateral ocular distribution, representing 80% (128/161) of the sample with varied anatomic locations, being the entire lens mainly observed with 35.4% (57/161). The most prevalent etiology, unknown, consisted of 32.9% (53/161) of the sample and the developmental stage revealed to be mainly incipient with 57.8% (93/161). Regarding the iatotropic stimulus, the unknown was the most frequent with 58.4% (94/161); yet vision was mostly preserved with 67.9% (108/159). Surgical treatment of cataracts was contra-indicated in 62.1% (100/161) of the sample. This work highlights the importance of sensitization early diagnosis of cataracts, in order to preserve vision and animal welfare.
