transillumination

[-ilo̅o̅′minā′shən]
Etymology: L, trans, through, illuminare, to light up
1 the passage of light through a solid or liquid substance.
2 the passage of light through body tissues for the purpose of examining a structure interposed between the observer and the light source. A diaphanoscope is an instrument introduced into a body cavity to transilluminate tissues.

transillumination

Clinical practice The shining of a light through a tissue or body region to detect masses or other lesions

trans·il·lu·mi·na·tion

(tranz'i-lū'mi-nā'shŭn)
Passage of light through a solid or liquid substance for diagnostic examination.

transillumination

A method of examination in which a bright light is shone through tissue to try to determine whether it contains abnormal structures such as a solid tumour.

Transillumination

A technique of checking for tooth decay by shining a light behind the patient's teeth. Decayed areas show up as spots or shadows.

transillumination 

1. The shining of light through a translucent membrane. This is principally used to better visualize ocular tumours, cysts or haemorrhages within the eye. It is accomplished by directing a narrow intense beam of light on the side of the eye. Example: If a tumour is present in the eye some light will not be reflected and the pupil will appear partially or completely black, instead of bright red as when the healthy eye is thus illuminated. Syn. transcleral illumination.
2. See retro- illumination.

transillumination (tran´siloo´minā´shən),

n 1. examination of an organ, cavity, or tissue (e.g., tooth or gingival tissue) by transmitted light. A valuable aid in detecting carious lesions, disclosing carious or demineralized dentin during cavity preparation, checking the finish or gingival margins of restorations, and revealing cement, debris, or calculus subgingivally.
2. a test in which the use of transmitted light may disclose a discoloration of the coronal aspect, indicating dentinal tubular hemorrhage as a result of trauma, pulpal necrosis, or fracture.
3. examination of tissues by means of a light placed so that the region under study is between the light source and the observer.

transillumination

the passage of strong light through a body structure, to permit inspection by an observer on the opposite side.

ocular transillumination
intense light placed on the sclera behind the ciliary body is transmitted to the interior of the eye, producing a tapetal reflex. Useful in identifying the presence of intraocular masses and demonstrating atrophy of the iris.
