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.

Veins network of the young quaking aspen leaf (Populus tremuloides) was magnified four times; in fact, the image of the leaf shown in Figure 1 was obtained by stitching multiple frames from a 4x deconvolution microscope with transillumination and coupled to a 1024 x 768[px.sup.2] CCD camera.

Pigment dispersion syndrome (PDS) results from posterior bowing of the iris and rubbing between the lens zonules and epithelial layer of the iris, and usually affects myopic eyes in men during the third to fourth decade of life.[sup][1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11] The literature indicated that Caucasians have the highest prevalence of PDS among all races,[sup][12] with clinical characteristics including Krukenberg spindle, homogeneous trabecular meshwork (TM) pigmentation, and spoke-like mid-peripheral iris transillumination defects (ITDs), which are referred as a triad of PDS.
