This paper describes the anatomy of the pig eyeball for easy use and interpretation by researchers who are considering their choice of animal model in vision sciences research.

Pig eyes share many similarities with human eyes, having a holangiotic retinal vasculature, no tapetum, cone photoreceptors in the outer retina, and a similar scleral thickness, rendering them valuable in comparative research.

2025年3月6日 · The short answer is: yes, pig eyes share several anatomical and functional similarities with human eyes, but there are also notable differences in color vision and visual acuity. This complex relationship makes pig eyes a subject of great interest in both veterinary and human medicine.

Regarding the eyelids, the main and most obvious difference between pigs and humans was the presence of the nictitating membrane, also known as the third eyelid, in the pig eyes . The nictitating membrane was situated at the medial angle of the eye and contained cartilage that provides structural support as the lid moves horizontally across the ...

2011年2月2日 · The eye of the domestic pig (Sus scrofa domestica) is an ex vivo animal model often used in vision sciences research (retina studies, glaucoma, cataracts, etc.). However, only a few papers have compiled pig eye anatomical descriptions.

2021年9月27日 · The purpose of this study was to elucidate, under which conditions abattoir-acquired pig eyes are suitable for refractive excimer laser experiments.

Pig eyes share many similarities with human eyes. 3–10 They are phylogenetically close to humans and have a holangiotic retinal vasculature, no tapetum, cone photoreceptors in the outer retina, 6 and similar scleral thickness. 7 Pig models have been developed for retinitis pigmentosa, glaucoma, and retinal detachment 6,11,12 and for studying ...

2011年2月1日 · The eye of the domestic pig (Sus scrofa domestica) is an ex vivo animal model often used in vision sciences research (retina studies, glaucoma, cataracts, etc.). However, only a few papers have...

Pig eyes are similar to human eyes in anatomy, vasculature and photoreceptor distribution. However, pigs have dichromatic vision, where only two pigment cones create colors, compared to the human trichromatic vision.

The pig eye is similar to the human eye in terms of anatomy, vasculature, and photoreceptor distribution, and therefore provides an attractive animal model for research into retinal disease. The purpose of this study was to characterize retinal histology in the developing and mature pig retina using antibodies to well established retinal cell ...
