RNFL asymmetry has been proposed as a strong indicator of optic neuritis, [7] [8] with one small study proposing that asymmetry of 5–6μm was "a robust structural threshold for identifying the presence of a unilateral optic nerve lesion in MS." [9] Optic neuritis is often associated with multiple sclerosis, and RNFL data may indicate the pace ...
The GDx nerve fiber analyzers measure the retinal nerve fiber layer (RNFL) thickness with a scanning laser polarimeter based on the birefringent properties of the RNFL. Measurement is obtained from a band 1.75 disc diameters concentric to the disc. It projects a polarized beam of a light into the eye.
Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [1] as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head and body, and weighed only ...
A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). [2] It is determined by collecting data from vast numbers of laboratory tests.
Successful training in dogs requires the owner/trainer to be able to correctly interpret the learning abilities of the dog. It is well established that body language can reveal emotions and moods of dogs, [1] [2] [5] [23] which can be quite helpful when assessing dogs during training.

GDV is a life-threatening condition in dogs that requires prompt treatment. It is common in certain breeds; deep-chested breeds are especially at risk. Mortality rates in dogs range from 10 to 60%, even with treatment. [2] With surgery, the mortality rate is 15 to 33 percent. [3]
A dog's coat is composed of two layers: a top coat of stiff guard hairs that help repel water and shield from dirt, and an undercoat of soft down hairs, to serve as insulation. [1] Dogs with both under coat and top coat are said to have a double coat. Dogs with a single coat have a coat composed solely of guard hairs, with little or no downy ...
