Obligatory medical device diagnostics.
- Color vision tests such as.
- Color charts according to Ishihara (Ishihara test).
- Anomaloscope according to Nagel
- Farnsworth test
- Panel D15 test
- Perimetry (visual field measurement)
Optional medical device diagnostics – depending on the results of the medical history, physical examination, laboratory diagnostics and mandatory medical device diagnostics – for differential diagnostic clarification.
- Electroretinography (ERG; recording of the electrical stimulus response to brief exposure to light) – to check the functional state of the outer and middle retinal layers.
- Visual evoked potentials – to detect damage in the course of the visual pathway.
- Optical coherence tomography (OCT) – for precise examination of the retina (especially the macula), vitreous and optic nerve.
- Computed tomography of the skull (cranial CT, cranial CT or cCT) – for differential diagnostic clarification.
- Magnetic resonance imaging of the skull (cranial MRI, cranial MRI or cMRI) – for differential diagnostic clarification.
