Fundus photography in animals: Fundus photography is a useful tool utilised for veterinary research, veterinary ophthalmology, as well as education. [20] Numerous studies have used it as a research method for the study of ocular and systemic conditions in animals. [21] [full citation needed]
The fundus of the eye is the interior surface of the eye opposite the lens and includes the retina, optic disc, macula, fovea, and posterior pole. [1] The fundus can be examined by ophthalmoscopy [ 1 ] and/or fundus photography .
Fundus photographs of the left eye (left image) and right eye (right image). Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disc is located towards the nose. Both optic discs have some pigmentation at the perimeter of the lateral side ...
Baseline color and black and white red-free filtered images are taken prior to injection. The black and white images are filtered red-free (a green filter) to increase contrast and often gives a better image of the fundus than the color image. A 6-second bolus injection of 2-5 cc of sodium fluorescein into a vein in the arm or hand
Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. [1] Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina , optic nerve head , blood vessels ...
In order to see a clear image, the eye must focus rays of light on to the light-sensing part of the eye – the retina, which is located in the back of the eye.This focusing – called refraction – is performed mainly by the cornea and the lens, which are located at the front of the eye, the anterior segment.

Retinal vessel analysis is a non-invasive method to examine the small arteries and veins in the retina which allows to draw conclusions about the morphology and the function of small vessels elsewhere in the human body.
