Abstract
A device for determining the presence of abnormal fluid in a middle ear of a subject includes an elongated probe, a first light source housed within the elongated probe, and a second light source housed within the elongated probe. The elongated probe includes a distal end for inspection of an ear. The First light source is configured to convey an optical beam through a tympanic membrane associated with the middle ear of the subject, without puncturing the tympanic membrane. The second light source is configured to convey light through the distal end of the elongated probe and illuminate the tympanic membrane.
