Illumination 2

Description : Adequate illumination is of paramount importance in otoscopy.

Originally the ear was examined by means of sunlight.

Wilde, in the mid 19th century, stated that examinations of the ear should be undertaken, if possible, between the hours of 11 a.m. and 3 p.m. He commented that during the winter months there were many days when there was insufficient light for accurate aural examination.

Clearly some form of artificial illumination was necessary.
