Diaphanoscopy

As diaphanoscopy (Greek diaphanes : translucent and skopein : See) refers to the continuous illumination of parts of the body by means of visible light for diagnostic purposes. Due to the development of more meaningful technical methods, diaphanoscopy has lost some of its importance. At the same time, new methods for diagnosing diseases in ear, nose and throat medicine and rheumatology were developed. In the experimental-clinical area, optical-tomographic approaches are also tested.

Examples of positive diaphanoscopy:

Examples of negative diaphanoscopy:

Testicular tumor
Incarcerated scrotal hernia

Example as an imaging part of an operative method:

Percutaneous endoscopic gastrostomy

history

The idea of diaphanoscopy already existed in 1867 when Julius Bruck developed the stomatoscope for x-raying the teeth and the urethroscope for x-raying the bladder with galvanic incandescent light . In 1903, the possibility of transillumination was tested and described for the localization of foreign bodies . The transpupillary diaphanoscopy was added in 1959. On the other hand, diascleral fluoroscopy attracted little attention due to insufficient light intensity , until 1965 a fiberglass diaphanoscope with a maximum illuminance of 40,000 lux was possible. This enabled smaller foreign bodies close to the wall to be displayed. Foreign bodies away from the wall and tissue compaction were problematic.

In order to diagnose diseases of the central nervous system in children, diaphanoscopy was used in cases of suspected subural effusions, cerebral edema and large hydrocephalus .
