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.
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
Fundus photographs of the right eye (left image) and left eye (right image), as seen from the front (as if face to face with the viewer). 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 ...
The value of the examination with the Retinal Vessel Analyzer has been documented in a number of recent studies. There is growing evidence that in particular the dynamic vessel analysis is able to detect blood vessel damage - for instance as a consequence of aging or metabolic disease - in an early stage. Some examples: Cardiology
Noyes conducted early studies on Fundus photography and took the first successful fundus photograph of a rabbit eye in 1862. [ 4 ] [ 5 ] As a founding member of the American Ophthalmological Society , established on June 7, 1864, Henry D. Noyes joined 18 other physicians, including Daniel Bennett St. John Roosa and Edward Delafield , the ...
If the view of the retina is not clear, imaging techniques such as ultrawide-field fundus photography, B-scan ultrasonography, and optical coherence tomography (OCT) may help to identify a detachment. [8] [13] [14] MRI and CT scans are less commonly used for the diagnosis of retinal detachment, but they may be useful in certain cases.
Sample view of anterior synechiae with indentation gonioscopy Indentation gonioscopy: An extension of the above two concepts, indentation gonioscopy involves the applied pressure of the goniolens against the eye, acutely raising the intraocular pressure in the anterior chamber and subsequently opening up the iridocorneal angle mechanically ...
