MARTINS, B.C et al. Ultrasonographic analysis of senile cataractous lens of dogs and its correlation to phacoemulsification. Arq. Bras. Med. Vet. Zootec. [online]. 2011, vol.63, n.5, pp.1104-1112. ISSN 1678-4162. http://dx.doi.org/10.1590/S0102-09352011000500010.
This study aimed to evaluate the effectiveness of a computer-assisted ultrasound analysis of senile dogs cataractous lens and identify its correlation to phacoemulsification surgical parameters. Simultaneous A- and B- mode ultrasonic evaluation of the lens was performed on 15 dogs with cataract. A computer-assisted image analysis was used to objectively calculate the lens echogenicity. Following ultrasonographic examination the cataracts were removed by phacoemulsification and the ultrasonographic and phacoemulsification findings were compared to identify possible correlations. Lens echogenicity obtained by the computer-assisted ultrasonographic analysis correlated to the phacoemulsification time, such that the whiter the ultrasound image, the longer was the phacoemulsification time. The B-mode ultrasonography was helpful for the prediction of lens opacity location, but not predictive of lens hardness.
