[Simultaneous photography or angiography of anterior and posterior eye segments in experimental animals].
Simultaneous photographic or angiographic studies of the anterior and posterior segments requires a considerable reduction in the respective parts of the negatives; this can be avoided by simultaneous study of the one segment ipsilaterally and the other contralaterally (this can also be performed vice versa). Differences and common properties of the eyes of rabbits and miniature pigs and the human eye are described. Apart from the monkey eye, the pig eye is most readily comparable with the human eye as regards vasotopographic and vasomorphologic conditions. In addition, the courses of angiographies in the eyes of experimental animals were observed; measurements of fluorescein inflow and circulation times in the anterior and posterior segments in miniature pigs are presented. These were subjected to significance tests: only the difference in the inflow and outflow of the dye in retinal vessels was found to be statistically highly significant. The difference in inflow between choroidal and retinal vessels was not significant, though this may have been due to an error of measurement. The techniques and measurements described represent the basis of observation in miniature pigs with experimentally induced hypertension.
