Popis: | One of the most important tasks in ophthalmology is the detection of thc visual field. The method therefore is called perimetry and the used devise is a permeter. Conventional perimeters work with subjective methods, where the patient has to signal the recognition of an applied light-stimulus by pressing a button. The cooperation of the patient is absolute necessary for a good result of the measurement. But, due to different causes, many patients can or will not cooperate that is why an objective method for perimetry is to be bound. A method of objective detection of the visual field is the usage of Visual Evoked Potentials (VHP). To reduce the measuring-time, multifocal stimulation has to be used. For multifucal Stimulation special sequences are necessary. A new form of sequences for perimetry is presented in this article. |
