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.
