3. This is the only type of ERg that tests the ganglion cells

5. A single layer of cells that greatly contributes to the standing potential of the eye

9. A macular scar will show up on this electrodiagnostic test

10. This part of the eye that has a positive charge (+6 mV in EOG)

Down

1. A connective cell that allows ions to travel between the reintal layers

2. A retinal disease that will show an abnormal EOG and normal ERG

4. The light rise divided by the dark trough on EOG

5. On flash ERG, this peak has a smaller amplitude and latency

6. Important piece of equipment (shown in class) needed for flash ERG testing

7. According to Dr. Yudcovitch, this type of skin resistance should be below 2 kOhms for electrodiagnostics

8. Takes 8 minutes or so to generate this EOG peak
