Oxidative effects of laser photocoagulation
Free Radical Biology and Medicine, 1991 Diabetic proliferative retinopathy is a common and sight-threatening condition. Oxidative stress is an integral and possibly causative part of the pathogenesis. Although laser photocoagulation is usually a beneficial treatment it remains unclear how it works.

Laser Photocoagulation of the Eye
Archives of Ophthalmology, 1963Introduction Recent advances in energy amplification techniques have culminated in the development of a new light source, the laser (optical maser).1-3The unusually intense, monochromatic beam which characterizes laser emission is of particular interest to the ophthalmologist and may find wide application in the biomedical sciences.4,5 The present ...

Laser Photocoagulation of the Iris
Archives of Ophthalmology, 1970Irides of rabbit, cat, monkey, and human eyes were exposed to ruby laser coagulation in an attempt to produce iridotomies. One monkey iris was exposed to the argon laser. The ability to produce an iridotomy was directly related to the degree of iris pigmentation. There was no observed damage to the corneas, lenses, or retinas of animals exposed.

Laser Photocoagulation for Gastrointestinal Bleeding
Clinics in Gastroenterology, 1978Endoscopic laser photocoagulation is one of the exciting developments in the field of gastrointestinal endoscopic therapy. However, much work needs to be done before these techniques should be allowed to proliferate into widespread use. There are few controlled randomized clinical studies evaluating any endoscopic treatment of bleeding, including argon

Simulator for laser photocoagulation in ophthalmology
IEEE Transactions on Biomedical Engineering, 1995The practice of laser photocoagulation plays a major role in the ocular therapy, but the persistence of many postoperative complications denotes genuine difficulty in mastering the technique. The authors present a device which, thanks to the use of simulation, enables actual practice to be dissociated from apprenticeship.

Clinical Studies in Laser Photocoagulation
Archives of Ophthalmology, 1965Introduction Very shortly after the first demonstration of laser action by Maiman in 1960, it was apparent that the laser could be an excellent source for photocoagulation. The characteristics of the laser which are of particular value in photocoagulation are the great energy output in a short time interval, its monochromatic nature, and the narrow ...

Clinical Photocoagulation With the Krypton Laser
Archives of Ophthalmology, 1972The first clinical application of the krypton laser has been reported. Ten patients with vascular retinopathies were photocoagulated with the monochromatic yellow krypton laser emission at λ568.2 nm λ5,682 Angstroms) and coagulations ranging between 150μ to 250μ in diameter were produced after one-fourth to onehalf second exposures with power levels of

Laser photocoagulation in alimentary bleeding
World Journal of Surgery, 1983AbstractLaser therapy is theoretically more advantageous than endoscopic techniques such as diathermy in the treatment of alimentary bleeding primarily because the bleeding point is not directly touched or handled during therapy and the amount of energy dissipated in the surrounding tissue is more easily controlled.

Archives of Ophthalmology, 1977
Argon Laser Photocoagulationby Zweng et al is a rather compact guide for the ophthalmologist who is interested in retinal diseases and their treatments. To begin, the authors present an understandable and informative chapter on the intricacies of laser light production. The various instruments that are now on the market are described.

Applied Optics, 1965
An exciting application of the laser lies in its use in the field of ophthalmology for photocoagulation of retinal and iris tissues. A hand-held ophthalmoscope-laser has been developed which has been used on numerous laboratory animals and recently on several hundred human beings.
