Is it possible (even remotely) for a person to accidentally misplace an eyeglass case (with eyeglasses) behind the glove compartment? If so, how would one go about searching behind the glove compartment?

 

If anything were to drop behind the glove box, it would drop on the passengers feet. to check behind the glove box, empty glove box, on the left and right sides push or pull the stops, the glove box will drop down to view the back side. the cabin filter is usually behind the box.
