Horizontal optokinetic nystagmus. The optokinetic reflex ( OKR ), also referred to as the optokinetic response, or optokinetic nystagmus (OKN), is a compensatory reflex that supports visual image stabilization. [ 1] The purpose of OKR is to prevent image blur on the retina that would otherwise occur when an animal moves its head or navigates ...
ICD-9-CM. 95.44. MedlinePlus. 003429. In medicine, the caloric reflex test (sometimes termed 'vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel prize in 1914 for this discovery.
Measuring the amount of protein in the urine helps to distinguish between different causes of proteinuria. [152] [153] Urine protein electrophoresis, which identifies and measures the proportions of different types of protein in the urine, may be used to investigate the cause of proteinuria [152] and to detect Bence-Jones protein.

Nephrotic syndrome is a collection of symptoms due to kidney damage. This includes protein in the urine, low blood albumin levels, high blood lipids, and significant swelling. Other symptoms may include weight gain, feeling tired, and foamy urine. Complications may include blood clots, infections, and high blood pressure.
Hartnup disease is a disorder of amino acid transport in the intestine and kidneys; otherwise, the intestine and kidneys function normally, and the effects of the disease occur mainly in the brain and skin. Symptoms may begin in infancy or early childhood, but sometimes they begin as late as early adulthood.
The dog's body weight should be determined and calculated once every two weeks using weight scale. [48] The daily caloric requirement by the dog's body and BCS should also be determined using a scale as part of dietary management in maintaining average body weight. The protein intake by the dog should also be considered and checked twice a month.
Nystagmus as seen in a case of ocular albinism. The cause of pathological nystagmus may be congenital, idiopathic, or secondary to a pre-existing neurological disorder.It also may be induced temporarily by disorientation (such as on roller coaster rides or when a person has been spinning in circles) or by some drugs (alcohol, lidocaine, and other central nervous system depressants, inhalant ...
Cystinuria is an inherited autosomal recessive disease [ 1] characterized by high concentrations of the amino acid cystine in the urine, leading to the formation of cystine stones in the kidneys, ureters, and bladder. It is a type of aminoaciduria. "Cystine", not "cysteine," is implicated in this disease; the former is a dimer of the latter.
