Göttingen Minipigs in Ocular Research

Abstract

Since their development in the 1960s, Göttingen minipigs have become a popular nonrodent animal model in biomedical research, especially for ocular studies, because of their ease of handling, size, well-monitored genetics, and ocular anatomy that is similar to humans. The purpose of this mini-review is to introduce the reader to the various ways in which this animal model is currently being utilized in ocular research and to provide an overview of the diagnostic modalities that aid in this research. To date, the Göttingen minipig has been used for a variety of ocular research endeavors, including studies evaluating the safety and efficacy of ocular therapeutics, glaucoma etiopathogenesis and treatment, novel biomaterials, surgical procedures, and implantable materials/devices. In addition to histopathologic evaluation of enucleated globes, the majority of these studies make use of advanced in vivo diagnostic techniques, including electroretinography, optical coherence tomography, fundoscopic imaging, and fluorescein angiography.
