Regarding HRT3, the correlation was 0. Normal subjects were examined twice, on successive days.

Graefe’s Arch Clin Exp Ophthalmol. This study aims to determine whether the visual field may influence the diagnosis of glaucoma.

The clinical judgment is the core of the medical profession. In the first phase, glauocma threshold values are estimated on the basis of examining only six points.

The loss of lens transparency due to cataracts, however, also produces diffusion of light in fundus images. Michelson G Scibor M.

Cinco pruebas comunes para el glaucoma | Glaucoma Research Foundation

This method had high reproducibility, good diagnostic capability, and diagnostic agreement with other morphologic procedures, similar to that when such procedures are mutually compared. Individuals with diabetes or other systemic diseases that could affect vision glaucoms history of neurologic disease were excluded from the study.


Mean Hb in sector 8 had a correlation coefficient of 0. The effect of perimetric experience in patients with glaucoma. Further, the method could be used to investigate whether perfusion changes are associated with IOP modifications either medical or surgicalas well as early defects that then would lead to tissue atrophy and the corresponding functional defect.

Campimefria of the patients had glaucoma with corresponding visual field, and the other half had physiological cupping and normal visual field. Subsequently, they provided consent for analysis and possible publication. The mean MD was Perez-OlivanNone; A. The reference value must be obtained inside the eye, and subject to the same variables.

No other information was given to those examiners. Diagnostic agreement kappa between Hb-GDF, and the morphologic and functional parameters ranged between 0. For example, a detector that captures three images, one centered on spectral component blue, another on green, and another on red, reveals that in areas with high Hb content, most of the light reflected is red, less is green, and even less is fn.

Hb levels correlated strongly with the Spark mean sensitivity first phase 0.

There was poor agreement between the examiners in the diagnosis of glaucoma Kappa: Send this article to a friend by filling out the fields below: They were camipmetria informed that all patients had glaucoma or suspicion of having glaucoma. A total of evaluations per group were performed: These results indirectly reflect the low accuracy of relating the optic disc with a given visual field.


Using different concentrations or different thicknesses of various red blood cell dilutions, it may be established experimentally that the photographic images obtained with this technique can be used to determine the amount of Hb.

In contrast, areas with a low Hb content reflect a lower proportion of galucoma red component compared to the green and blue light.

Healthy subjects are represented by the x’s and glaucoma patients are represented by the circles. The technique is relatively easy to apply and the majority of eye clinics already possess the campimetrai equipment, but each camera requires a specific correction of the function based on measurements acquired from a series of healthy subjects.

The knowledge of the results of the visual field can influence the judgment of the diagnosis of glaucoma. Systems for fundus imaging measure the amount of light reflected at different wavelengths. The order in which the slides were presented was also randomized.
