Sentences with phrase «of electroretinography»

In many dogs secondary cataracts develop, which might become extensive enough to obscure the retina and require the use of electroretinography (ERG) for diagnosis.

The purpose of electroretinography is to determine whether the retina is functioning properly.

Not exact matches

My research is focused on the pathophysiology of retinal ganglion cell (RGC) axon damage in glaucoma and detecting early - stage abnormalities by means of non-invasive imaging, psychophysical testing and electrophysiological measures such as electroretinography (ERG) and visually evoked cortical potentials (VEP).

Other specialized testing (such as electroretinography (to test the electrical activity of the retina) or ocular ultrasound (to evaluate the eye or orbit when direct evaluation is not possible) may be recommended and can usually be performed the same day as the appointment or the scheduled day of surgery.

While the diagnosis of retinal degeneration is made by ophthalmoscopy and / or electroretinography, genetic testing for PRA can be useful for breeders to identify not only affected animals, but those that are genetic carriers for the disease.

ERG - Electroretinography; a test done by an ophthalmologist to assess the functioning of the retina, the light sensing and vision producing layer of cells at the back of the eye.

Electroretinography assesses the electrical activity of the retina, thus giving an accurate assessment of retinal function.

Electroretinography can detect these conditions and therefore determine if a pet is blind from disease of the retina.

Gonioscopy, tonometry, Schirmer tear test, electroretinography, and ultrasonography are not routinely performed; thus, dogs with goniodysgenesis, glaucoma, keratoconjunctivitis sicca (dry eye), early lens luxation / subluxation or some early cases of progressive retinal atrophy might not be detected without further testing and do not qualify for this type of exam.

A subsequent electroretinography study identified an initial reduction of the cone photoreceptor function which led to the condition being re-classified as a cone - rod dystrophy (CRD), rather than a rod - led PRA, and the disease was termed CORD1 for cone - rod degeneration 1 [36].

Evaluation of retinal function in 15 Swedish vallhund dogs (nine dogs at Stage 2, two dogs at Stage 3, and four normal control dogs) by electroretinography revealed a decrease of both rod and cone photoreceptor - mediated function in Stages 2 and 3 (Fig. 3).

Electroretinography revealed a gradual loss of both rod and cone photoreceptor - mediated function in Stages 2 and 3 of the disease.
