Clinical trials: Amplitude
Tumor of Pituitary and Suprasellar Region
Tegaderm and Visual Evoked Potentials
The purpose of this study is to determine if a clear barrier placed over the eyes has any effect on goggle monitoring. When a patient has general anesthesia they lose the ability to blink and their eyes may dry.
