Detecting early glaucoma by assessment of retinal nerve fiber layer thickness and visual function. GDx-VCC-measured parameters may serve as a useful tool to distinguish normal from glaucomatous eyes; in particular, NFI turned out to be the best discriminating parameter.

However, when glaudoma comes to differentiating the severity of glaucoma, GDx VCC demonstrates only a moderate ability.

Glaucoma detection using the GDx nerve fiber analyzer and the retinal thickness analyzer (RTA).

This is a huge problem. The subject’s pupil was left undilated and the room lights were kept on.

All subjects underwent were assessed by means of glajcoma GDx VCC imaging technique within 3 months of the clinical examination and visual field testing.

The sensitivity and specificity of nerve fiber layer measurements in glaucoma glajcoma determined with scanning laser polarimetry. The exposure of his story led to increased public awareness of the need for every one over forty to have an eye exam, even if the person has no symptoms or complaints.


Morphometric analysis of human peripapillary retinal nerve fiber layer thickness. You can manage this and all other alerts in My Account.

A comparison of HRT II and GDx imaging for glaucoma detection in a primary care eye clinic setting.

Screening tests are particularly important if any close family member suffers from glaucoma. There is a famous story of a well-known baseball player in the US who suffered unknowingly from advanced glaucoma. Besides, the results of the present work are in good agreement with previous reports, where GDx VCC demonstrated excellent diagnostic capability in glaucoma in a purely Chinese population, even in its early stages.

The glauxoma fiber layer is important because it is the tissue that the optic nerve is made of.

Which numbers in the GDx test is a glaucoma specialist interested in? GDx Nerve Fiber Analyzer. It is not that hard to do. This monitoring allows us to adjust treatment appropriately based on the severity of disease in each eye. The ROC-curve comparison was done according to the method proposed by Hanley et al. End of highlights for August 23rd chat. In all statistical analyses, we set significance at 0.

As far as I know, the numbers that are most important are the actual thickness glaucomz. All images had to be of high quality, i. The area under the receiver operating characteristic AROC curve was used to assess the ability of each parameter to differentiate normal eyes from glaucoma eyes, for each of the established glaucoma subgroups.


Pay attention to the fact that damage is also seen in the lower part, which the visual field test did not succeed in indicating upper half of visual field looks normal in picture A. This research follows the tenets of the Declaration of Helsinki.

GDx Nerve Fiber Analyzer – Glaucoma Service Foundation to Prevent Blindness

Do insurance companies reimburse for the GDx test? Presented in part at: Glaucoma is a common disease, which usually occurs, in older age. That should be enough to make it a good test. The optic nerve is damaged in glaucoma because of increased intra-ocular pressure, pressure that, over time, damages optic nerve fibers. The superior and inferior poles are usually affected first. There are two methods to measure the severity of damage caused by glaucoma.

Sorry not to talk so people can understand. Do you think it will become a standard diagnostic tool for testing glaucoma in the future? The mean age was Glaucoma detection using gllaucoma laser polarimetry with variable corneal polarization compensation.
