In such instances severalbright points of light are often seen upon the surface of themembrane below the level of the fluid. These multiple reflexesare indicative of the presence of fluid, although they must notbe relied upon as absolutely characteristic of this with the catheter or by Politzers method will reveal,through the diagnosis tube, the characteristic bubbling as soonas the air enters the middle ear.
