Interstitial laser coagulation of the prostate
Atlas of the Urologic Clinics, 2002Interstitial laser coagulation (ILC), is the interstitial application of laser energy to achieve tissue coagulation by a thermal process. This is achieved by implanting the laser delivery fiber directly into the target tissue and firing the laser. As a treatment for benign prostatic hyperplasia, ILC has been investigated and used clinically.

This chapter is about complications of laser coagulation of newborn. Colour pictures and angiography pictures show in detail examples of eyes with an undertreatment or overtreatment of the retina after laser photocoagulation. An incomplete laser coagulation results often in a progression of the ROP disease and must be avoided.

Technique and results of interstitial laser coagulation
World Journal of Urology, 1995By use of thermal "ablation" techniques to apply heat to the prostate from the urethra, the coagulation volume is limited by the limited penetration depth of suitable radiation sources, e.g., lasers, and by heat conduction. Secondarily, the coagulated tissue is removed by sloughing. Interstitial heat application was expected to overcome these problems.

Lasers of various wavelengths are available for photocoagulation involving laser application in the macular area. The advantages of using lasers for photocoagulation are a smaller spot size as a result of optimum focalization and the theoretical, but rarely realized, benefit of a well-defined depth of activity of the monochromatic light, since the ...

Analog solution of laser retinal coagulation
Medical Electronics & Biological Engineering, 1965A mathematical calculation of the extent of retinal coagulation which results when a focused laser beam is incident on the retina, is described. For the chosen model of the eye an analytic solution of the diffusion equation was not possible; however, a resistance-capacity analog enabled the temperature distribution as a function of time to be obtained ...

Histology of Human Ocular Laser Coagulation
Archives of Ophthalmology, 1966This report describes the gross and microscopic changes induced by the laser beam in two human eyes. To our knowledge this is the first such description in the medical literature. The two eyes were to be enucleated for malignant melanoma. Therefore, with the permission of the patients, the retina of each eye was exposed to laser energies, as if the ...

Diode lasers for interstitial laser coagulation of the prostate
SPIE Proceedings, 1995The concept of interstitial laser coagulation (ILC) of the prostate is the generation of intraprostatic lesions of large volumes, which secondarily are resorbed. In previously published experimental and clinical studies Nd:YAG lasers in combination with specially designed light guides were used.

Periocular Skin Reshaping by CO2 Laser Coagulation
Aesthetic Plastic Surgery, 1996When blepharoplasty is performed by transconjunctival route, sometimes the excess of skin created by overlaxness of the lower lid does not retract to achieve the desired cosmetic result. We propose a method for controlled retraction of the eyelid by coagulating the skin using the CO2 laser.

Free-Beam and Contact Laser Coagulation
Journal of Endourology, 2003Laser coagulation of benign prostatic hyperplasia (BPH) encompasses a variety of techniques using different laser wavelengths, application systems, and surgical techniques to achieve contrasting tissue effects. During transurethral laser coagulation, known as visual laser ablation of the prostate (VLAP), the prostate is irradiated by free-beam Nd:YAG ...

Laser Coagulation of the Anterior Segment
Archives of Ophthalmology, 1967The irides of ten pigmented Dutch rabbits were coagulated with the pulsed ruby laser (0.3 joules). Single firings produced atrophic hyperpigmented lesions. The hyperpigmentation was due to pigment filled macrophages. In another group of young pigmented Dutch rabbits, laser coagulations were done on each eye in two peripheral iris sites.
