• eyesight | • insight | • foresight |
precision & development for exact diagnostics |
understanding vision for novel therapies |
education of the next generation |
We are part of the Ophthalmic Department of the University Magdeburg and apply a broad methodological bandwith to investigate structure und function of the eye and visual brain. We aim at precise diagnostics and the preparation of novel therapies by modern vision research.
• Our diagnostics cover subjective and objective testing of structure and function of the visual system (form for functional diagnostics).
• Our research aims at the understanding of physiology, pathophysiology und plasticity of the human visual system and its function.
• The education of the competent next generation of technicians, students, clinicians and scientists and the development of innovative aproaches are important pilars of our mission.
