Research Involvement

Dr. Panorgias’ lab, recently developed a system to improve the spatial specificity of an eye test called the multifocal electroretingram (mfERG). This non-invasive test records the retina’s electrical activity when stimulated by light. A persistent challenge is the involuntary, subtle eye movements that occur even when we maintain a fixed gaze, affecting the spatial specificity of the mfERGs – our ability to identify the exact retinal region that produces the recorded signal. To address this, we’ve developed a system that tracks eye movements in real-time, adjusting the light stimulus’ location to match the eye’s shifts. This approach aligns the light stimulus with the same retinal area consistently, increasing spatial specificity. Our rigorous experiments confirm the system’s feasibility and its potential to substantially enhance the diagnostic value of mfERGs, marking a significant advancement in ocular diagnostics.

If you are interested in the hardware/software integration of this project, please contact Dr. Panorgias directly.
