COMPUTER ASSISTED ERG ACQUISTION AND ANALYSIS-BIOMEDICAL PROJECTS

SUMMARY ABOUT THE PROJECT

The electroretinogram (ERG) records voltage responses of the retina to light stimuli.

This project’s goal was to design an interface in LabVIEW that would monitor, control, and record values from the ERG corresponding to liquid delivery, light intensity, flash duration, flash frequency, and voltage responses.
We integrated all of these controls while updating the graphical user interface (GUI) so that it was easy
to navigate in a dark room under a red filter.

Up to eight different solutions can be delivered, and only one solution is delivered at a time. Light intensity is controlled by setting a number on a filter wheel through the interface. An option to export data to Microsoft Excel is included along with real‐time graphs.

All relevant functionality present in a previous version of the interface was preserved, and input
points were organized into tabs so that real‐time graphs could be enlarged and the interface did not
look cluttered.
