OBJECTIVES The phenomenon of 'eye-shine' is seen in a variety of animal species, and is generally thought to be related to the presence of an intraocular reflecting structure, the tapetum lucidum. [] Key Method Morphologic observations were made from paraffin and plastic embedded specimens. Specimens were treated with traditional stains and observed by light and transmission electron microscopy. RESULTS Some species (primates, squirrels, birds, red kangaroo and pig) do not have this structure and they…

MORPHOLOGICAL ASPECT OF TAPETUM LUCIDUM AT SOME DOMESTIC ANIMALS

An eye fundus examination, in animals of different species : cattles, sheep, pigs, dogs cats and rabbits, to determine the presence or absence of tapetum lucidum, and his characteristics by species to species, age and even breed.

MORPHOLOGICAL AND BIOREFLECTING CHARACTERISTICS OF TAPETUM LUCIDUM IN DOGS AND COWS

The results of this research indicate that the anatomy of the eye, particulary shape of the pupil, placement of the eyes on the animals' head, and diet, all affect the morphology and bio-reflecting characteristics of this structure.

The fine structure of the turbot eye (Scophtalmus maximus): A macro‐anatomical, light and scanning electron microscopical study

This study is the first to present detailed descriptions of morphological structures and morphometric data for all the layers of the turbot eye using gross, light and scanning electron microscope examinations.

Ocular comparative anatomy of the family Rodentia.

There is little information regarding ocular anatomy and histology in many of the rodent species, and the springhaas was the only rodent in the authors' collection that presented a well-developed tapetum lucidum fibrosum.

Relationship between distribution of tapetum fibrosum and retinal pigment epithelium in the sheep eye.

It is suggested that approximately 55% of the histological tapetal area is covered with the nonpigmented area and is functional under a natural light condition.

The fibrous tapetum of the horse eye

The macroscopic tapetal shape, relationship between the Tapetal thickness and the degree of pigmentation of the retinal pigment epithelium (RPE), spatial relationship betweenThe visual streak and the tapetum, and wavelength of the light reflected from theTapetum in the horse were clarified.

Ocular microscopy of Bradypus variegatus

Bradypus variegatus, popularly known as common sloth or brown‐throated sloth, is a species with wide geographical distribution in Brazil. Expand on the literature about the species, we aimed to

Ocular morphology of the fruit bat, Eidolon helvum, and the optical role of the choroidal papillae in the megachiropteran eye: a novel insight.

The presence of reflective materials of the tapetum lucidum on the undulating retina was shown to be a morphological adaptation for increased light sensitivity as eachParabolic surface of the choroidal papillae served as a convex mirror, reflecting the light rays to the adjacent parabolic surface, thus sensitizing photoreceptors in affected regions.

The glow of the night: The tapetum lucidum as a co‐adaptation for the inverted retina

It is hypothesize that the tapetum lucidum is a compensatory adaptation for the suboptimal design of the inverted retina of vertebrates.

The retina of the collared peccary (Pecari tajacu): structure and function

The collared peccary's retinal features for the first time are described and a comparison of the findings with data from other ungulate species shows some similarities between the peccaries and pig retinas.
