    abstract = {With the aim to establish a correlation between ocular measurements 
  and individual factors, 110 healthy adult donkeys of different sizes and age 
  were used giving a total of 220 eyes. On each donkey ocular ultrasonography 
  was performed and the Globe Axial Length (GAL), Anterior Chamber depth (ACd), 
  Vitreous depth (VCd), Lens diameter (Ldi) and Lens thickness (Lt) were measured. 
  The differences between groups of animals, divided according to the gender, 
  weight (<200 and ≥200 kg) and age (<10 and ≥10 years) categories 
  have been estimated. No gender differences have been found. After application 
  of analysis of variance all measurements with exception of Lt were found to 
  be correlated with the weight while only Lt had a statistical significance for 
  differences between age categories. As in people a relationship between age 
  and lens thickness has been established in the present work for donkeys. It 
  appears that as with the horse, the donkey lens grows throughout the life of 
  the animal. These data could act as a pilot study to establish the growth pattern 
  of the crystalline lens in the donkey and its relationship to the incidence 
  of some important diseases.}
