[Evaluation of changes in the visual field in glaucoma during examination with white and colored stimuli]. / Hodnocení zmen zorného pole u glaukomu pri vysetrení bílými a barevnými stimuly.

In a group of 35 eyes with open angle glaucoma the visual field was examined by means of standard white perimetry and coloured blue-yellow perimetry. The results of the two types of examination of the central visual field were evaluated by statistical analysis where the assessed statistical parameters of the visual field of the investigated eyes with glaucoma we recompared. In the group a significant difference was found in the mean sensitivity of the retina (MS), mean loss of sensitivity (MD) and loss variance (LV) between white and coloured perimetry. The investigated indexes of the visual field in coloured perimetry differed significantly as compared with standard perimetry, i.e. the values of median sensitivity were lower and those of the mean loss of sensitivity were higher. From the results of our investigation ensues that coloured perimetry was a more sensitive method for the detection of changes of the visual field in a group of eyes with open angle glaucoma than conventional white perimetry.

Transient global amnesia: a quantified electroencephalographic study.

In 13 patients who experienced transient global amnesia (TGA), quantified electroencephalographic (qEEG) records were carried out within 1 week of the episodes, and compared with those in 13 cases with cerebral transient ischemic attacks (TIA), and 13 normal controls, matched for age and sex. A statistical comparison of the absolute power showed few differences between TGA and TIA patients, and many statistical differences between TGA patients and controls. The qEEG pattern reveals an involvement of the temporo-parietal structures in TGA patients. These findings suggest the presence of subclinical sequelae, after the TGA attack.
