Preferred Label : tapetum lucidum of camera-type eye;
Uberon definition : A layer of tissue in the eye of many vertebrate animals, that lies immediately behind
or sometimes within the retina. It reflects visible light back through the retina,
increasing the light available to the photoreceptors;
Uberon synonym : tapeta lucida; tapetum lucidum; tapis luisant@fr;
Uberon Function note : It normally functions at low light levels to provide the light-sensitive retinal cells
with a second opportunity for photon-photoreceptor stimulation, thereby enhancing
visual sensitivity;
Uberon Taxon note : Two morphologic types of tapetum lucidum can be observed in the eyes of fish: one
in the choroid that occurs in elasmobranchs, and the other which occurs in teleosts
and lies in the pigment epithelium of the retina;
