Cataratas no cão

Abstract

Para que um animal apresente uma boa visão, é importante que os diferentes meios oculares se encontrem saudáveis. Em particular, a transparência é uma característica crucial para o atravessamento de feixes luminosos e consequente acuidade visual. O cristalino, uma estrutura transparente, é responsável por fazer convergir os raios luminosos sobre a retina. Porém, diversos fatores podem influenciar a transparência da lente, tornando-a, em alguns casos, completamente opaca. Esta oftalmopatia tem a designação de catarata e é a doença mais comum responsável por défices visuais e cegueira em cães. Atualmente o tratamento para restauro da visão é apenas cirúrgico. A taxa de sucesso da cirurgia de remoção de catarata tem aumentado nos últimos anos, principalmente com a técnica de facoemulsificação. Um dos fatores críticos para o sucesso cirúrgico passa pela prevenção de possíveis complicações pós-cirúrgicas, por exemplo através da administração de fármacos. Hoje em dia, estima-se que em 95% dos casos é possível restabelecer a visão do animal. Na presente Dissertação de Mestrado, pretende-se apresentar uma abrangente revisão bibliográfica sobre a catarata em cães, complementada com diversos casos clínicos desta doença.

With the purpose of the animal having a good vision, it is important that the different ocular means are transparent, since the light beams will cross them. The lens, which is a transparent structure, is responsible for converging these light rays into the retina. However, there are several factors that may influence the transparency of the lens, making it completely opaque in some cases. This ophthalmopathy is called cataract and it is the most common disease responsible for visual deficits and blindness in dogs. Currently, the treatment to restore vision is only surgical. The success rate of cataract removal surgery has increased in recent years, especially with phacoemulsification technique. It is important to avoid and to prevent possible post-surgical complications, some of which are controlled by the administration of medication. Nowadays, it is estimated that in 95% of cases it is possible to restore sight of the animal. Therefore, this present Masters dissertation will present a literature review on cataracts in dogs and several canine clinical cases with this pathology.
