The tapetum lucidum is a reflective layer found in the eyes of many animals, including humans. It is located behind the retina and is composed of guanine crystals, which reflect light back towards the retina. This reflection enhances the amount of light available for image formation, improving visual acuity, especially in low-light conditions. The tapetum lucidum is most prominent in nocturnal animals, where it plays a crucial role in night vision. In humans, the tapetum lucidum is present in the eyes of infants and some adults, but it degenerates over time, becoming less visible as people age. The presence of a tapetum lucidum can be determined through a fundus examination, where the reflective layer appears as a silvery sheen on the back of the eye.
