The eyes, like other parts of the body, undergo changes after death. These changes are primarily due to the cessation of blood flow and the decomposition process.
Changes to the Eyes After Death
- Corneal Cloudiness: The cornea, the clear outer layer of the eye, starts to cloud over due to the lack of oxygen and nutrients. This cloudiness can become more pronounced with time.
- Pupil Dilation: The pupils, which normally constrict in response to light, dilate after death. This is because the muscles controlling the pupils relax.
- Eyelid Drooping: The eyelids may droop slightly due to the relaxation of the muscles that hold them open.
- Loss of Eye Pressure: The pressure inside the eye, known as intraocular pressure, decreases after death. This is because the fluid inside the eye is no longer being produced or circulated.
- Decomposition: Over time, the eyes, like other tissues, will begin to decompose. This process can be slowed down by refrigeration or embalming.
Importance of Eye Donation
Despite the changes that occur after death, the eyes can still be used for donation. Corneal tissue can be transplanted to restore vision in individuals with corneal blindness. Eye donation is a valuable gift that can improve the lives of others.
