Resumo
A avaliação da lente pela ultrassonografia, previamente à facoemulsificação, pode fornecer informações relevantes, notadamente, quanto ao seu aspecto e dimensões, que permitem delinear estratégias cirúrgicas mais seguras e com melhores resultados. Nesta pesquisa, realizou-se a biometria da lente de cães acometidos por catarata senil imatura, madura ou diabética, previamente à facoemulsificação, valendo-se da ultrassonografia em modo A e B, simultaneamente. Os valores obtidos para o diâmetro axial do bulbo do olho, câmara anterior, lente e câmara vítrea foram, respectivamente, 19,22mm, 2,35mm, 7,94mm e 8,94mm. Lentes cataratogênicas pertencentes a animais diabéticos apresentaram dimensões maiores (8,90mm), comparativamente àquelas que apresentavam catarata madura (8,12mm). Lentes acometidas por catarata imatura apresentaram menor dimensão (7,06mm), comparativamente às demais.
The evaluation of lens by ultrasonography, previously to phacoemulsification, can offer relevant information, markedly such as aspects and dimensions, allowing design safer surgical strategies with enhanced outcomes. Within the contents of this research, the biometry was performed in lens of dogs with senile immature, mature, and diabetic cataracts, previously to phacoemulsification, using mode A and mode B ultrasonography, simultaneously. The values obtained for axial diameter of the eyes, anterior chamber, lens, and vitreous chamber were, respectively, 19.22mm, 2.35mm, 7.94mm, and 8.94mm. Diabetic cataractous lens were larger (8.90mm), compared to mature cataract (8.12mm). Lens with immature cataract were smaller in dimension than those with mature and diabetic cataracts.
