Lighting in the operating room presents a complex array of hazards from both too little and too much light in the surgeon's view, as well as for the others who perform visual tasks. The relationship between the general lighting and the task lighting is assuming greater importance in the prevention of fatigue and in the elimination of some of the disability that may arise from glare. Fiberoptic supplemental illumination may prove valuable. At present, however, it entails certain problems of instability of equipment and possibly excessive delivery of light which is transformed into heat in the tissues.
