Does the smaller viewing window of a pocket otoscope make it more difficult to see the eardrum than it would with the larger professional otoscopes that have a larger viewing window?
Even though the viewing window is smaller on our pocket otoscope than it is on larger professional models it does not limit what you see in the ear canal. The limiting factor on an otoscope is not the viewing window size but the diameter of the specula tip that is being inserted into the ear canal.
