Archives of Ophthalmology, 1966
Diabetic retinopathy, which may soon become the chief cause of blindness in this country, is one of the great challenges to internist and ophthalmologist alike. The frequent failure of medical treatment to prevent blindness has encouraged a direct attack on the ophthalmological problem. In the past, diathermy treatment has been used with some degree of

Photocoagulation of Iris and Retina
Archives of Ophthalmology, 1958The eye offers unique opportunities for study of the effects of focused radiant energy because of the transparency of the media. Because radiation affects only those tissues in which it is absorbed (Draper's law), visible and infrared rays pass through the transparent media of the eye and may damage only those tissues which absorb this energy—the ...

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 ...

Photocoagulation in Eales' disease
Ocular Immunology and Inflammation, 1993Between 1970 and 1991 the authors examined 466 cases with Eales' disease. 359 eyes of 295 of these 466 cases received photocoagulation treatment. The mean age was 30.4, ranging between 14 and 55 years. Ten eyes with persistent vitreous hemorrhage underwent pars plana vitrectomy before photocoagulation.

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.

Photocoagulation for Choroidal Neovascularization
Ophthalmology, 1983Nearly 90% of severe visual loss among patients with senile macular degeneration can be ascribed to the neovascular form of the disease. The Senile Macular Degeneration Study demonstrated that argon laser photocoagulation can reduce the risk of severe visual loss by more than 60% among patients with choroidal new vessel membranes 200 microns or greater

Photocoagulation of Malignant Melanoma
Archives of Ophthalmology, 1979A 59-year-old woman developed a pigmented, expanding posterior pole choroidal lesion nasally that was clinically consistent with malignant melanoma. She refused enucleation, but agreed to a trial of photocoagulation therapy. Four weeks after photocoagulation, a reaccumulation of pigmentation and apparent elevation prompted a second photocoagulation ...

Photocoagulation of angioma of the eyelid
Albrecht von Graefe's Archive for Clinical and Experimental Ophthalmology, 1975An infant with a large hemangioma (strawberry mark with a cavernous component) of the eyelid was successfully treated with photocoagulation. The method resulted in rapid involution of the lesion and the visual function of the involved eye could be preserved.

Photocoagulation in Congenital Retinoschisis
Archives of Ophthalmology, 1970Photocoagulation applied to the retinoschisis cavity in five eyes with congenital retinoschisis not only failed to ameliorate the disease but caused holes in the external layer, or both layers, and subsequent retinal detachment. Until more is learned about the pathogenesis and course of congenital retinoschisis, it is recommended that photocoagulation ...

Macular Photocoagulation Study
Archives of Ophthalmology, 1984To the Editor. —In response to Sabates et al, 1 who recently voiced some concerns about the Macular Photocoagulation Study (MPS), 2 we offer the following comments: The authors stated that we did not consider time of treatment as a factor in evaluating the outcome of laser treatment. In fact, the vast majority of patients enrolled in the National Eye
