| photocoagulation | <technique> A cancer treatment in which a laser is used to destroy blood vessels entering a tumour in order to deprive the tumour of its nutrients. (31 Dec 1997) |
| photocoagulator | The apparatus used in photocoagulation. Laser photocoagulator, a high-energy source of electromagnetic radiation. See: laser. Xenon-arc photocoagulator, a photocoagulator in which a xenon-arc bulb delivers radiation from the visible and near-infrared spectrum. (05 Mar 2000) |
| photodermatitis | Dermatitis caused or elicited by exposure to sunlight; may be phototoxic or photoallergic, and can result from topical application, ingestion, inhalation, or injection of mediating phototoxic or photoallergic material. See: photosensitization. Synonym: actinic dermatitis, actinodermatitis. Origin: photo-+ G. Derma, skin, + -itis, inflammation (05 Mar 2000) |
| photodistribution | Areas on the skin that receive the greatest amount of exposure to sunlight, and which are involved in eruptions due to photosensitivity. (05 Mar 2000) |
| photodrome | <physics> An apparatus consisting of a large wheel with spokes, which when turning very rapidly is illuminated by momentary flashes of light passing through slits in a rotating disk. By properly timing the succession of flashes the wheel is made to appear to be motionless, or to rotate more or less slowly in either direction. Origin: Photo- + Gr. To run.

| photodynamic | Relating to the energy or force exerted by light. Origin: photo-+ G. Dynamis, force (05 Mar 2000) |
| photodynamic radiation therapy | <oncology, technique> A light sensitive drug is given through a vein and concentrates in the tumour. Then, during a surgical procedure, a special light activates the drug. The activated drug kills tumour cells. (31 Dec 1997) |
| photodynamic sensitization | The action by which certain substances, notably fluorescing dyes (acridine, eosin, methylene blue, rose bengal) absorb visible light and emit the energy at wavelengths that are deleterious to microbes or other organisms in the dye-containing suspension, or selectively destroy cancer cells sensitised by intravenous porphyrin and exposed to red laser light. Synonym: photosensitization. (05 Mar 2000) |
| photodynamic therapy | <oncology, technique> Cancer treatment that uses the interaction between laser light and a substance that makes cells more sensitive to light. When light is applied to cells that have been treated with this substance, a chemical reaction occurs and destroys cancer cells. (31 Dec 1997) |
