Pig eyes play a vital role in various scientific, medicinal, and educational fields. Their anatomical and physiological similarity to human eyes makes them an indispensable resource in advancing our understanding of ocular diseases, as well as testing new pharmaceuticals and medical devices.
In addition to many other uses, pig eyes are used for:
- Glaucoma research
- Cataract research
- Macular degeneration research
- Surgical procedure tests
- Assessing the safety of chemicals, cosmetics, and pharmaceuticals
- Medical device testing
- Xenotransplanation
- Human corneal transplants
- Dry eye syndrome drug trials
- Diabetic reinopathy drug trials
Scientific Research Applications
Ophthalmological Studies
Pig eyes are frequently used in research focused on eye diseases such as glaucoma, cataracts, and macular degeneration. Their structural similarity to human eyes enables researchers to:
- Study the progression of these diseases.
- Test new surgical procedures like laser treatments.
- Develop pharmaceutical solutions.
For example, researchers have recently used pig eyes to test the efficacy of picosecond ultrashort laser pulses as a viable alternative to nanosecond laser pulses for use in ophthalmic surgeries. They found that the ability to scale down the pulse energy of the laser to a lower level (down to 10 of microjoules, rather than millijoules), allowed more precision and less fraying, in addition to lower heat input during ablation.
Researchers were able to determine picosecond ultrashort lasers were more effective than state-of-the-art ophthalmic nanosecond lasers, which creates opportunities for future surgeries to use smaller, simpler, and more cost-effective laser sources.
Toxicology Testing
Pig eyes are used in toxicology studies to assess the safety of chemicals, cosmetics, and pharmaceuticals. Ex vivo models using pig eyes provide reliable data without the use of live animals.
Researchers used pig eyes as a means to test pure benzyl-Brilliant Blue G (PBB) for use in retinal surgery. They performed the test by slowly placing 40 microliters of each formulation over the retinal surface for 30 seconds. The pig eye model allowed them to test how well PBB stained the internal limiting membrane compared to other existing dyes, as well as confirming the dye was not toxic to retinal cells.
Other dyes have presented possible toxic effects in humans, and porcine eyes provide a way to develop safer and more effective surgical tools for human retinal procedures.
Biomaterial and Device Testing
Medical devices such as intraocular lenses and surgical tools are often tested on pig eyes before being approved for human use. This ensures the safety and efficacy of devices designed to improve vision.
A recent study to develop a highly sensitive liquid metal-based contact lens sensor for continuous inocular pressure monitoring involved the use of porcine tissues in tests. Pig eyes were used in both ex vivo and in vivo testing to validate the sensor’s performance on tissues similar to that of humans.
The tests demonstrated the sensor’s potential for non-invasive monitoring and continuous inocular pressure monitoring, which is crucial to treating glaucoma.
Medicinal Applications
Xenotransplantation
In the field of xenotransplantation, pig eyes are being explored as potential substitutes for human corneal transplants. Research has shown promising results in adapting pig corneas for use in humans, particularly in regions where donor tissue is scarce. Global blindness is estimated at 36 million per year, and one of the top causes is corneal blindness. Exploring porcine corneal transplants could help millions of patients.
For example, a new porcine-derived corneal scaffold may help address a global shortage of transplantable corneas. By using a supercritical carbon dioxide technology, porcine eyeballs can be synthesized into a collagen structure that is identical to that of humans, which allows stem cell growth and corneal regeneration. It offers a safe and efficient solution for millions of patients worldwide who suffer from corneal blindness.
Drug Development
Preclinical trials of drugs targeting eye conditions like dry eye syndrome or diabetic retinopathy often use pig eyes to evaluate their effects on ocular tissues.
A recent study used porcine eyes to demonstrate a new method of real-time monitoring of antiglaucoma drug concentrations in the anterior chamber of the eye. Porcine eyes were used as an ex vivo model to measure the distribution of the drug via boron-doped diamond microelectrodes. The technique proved effective in monitoring drug concentrations, and opens up new opportunities in drug monitoring as well as glaucoma treatment strategies.
