Xenon arc photocoagulation for treatment of subluxation of lens.

A comparative trial of xenon arc and argon laser photocoagulation in the treatment of proliferative diabetic retinopathy.

We present the results of a randomised study comparing xenon arc and argon laser photocoagulation in the treatment of proliferative diabetic retinopathy. Our results show that when used in the way described below there is no significant difference between the effect of the 2 treatments on optic disc neovascularisation and visual acuity. We also compare the results of peripheral retinal ablation...

Vitreous fluorophotometry evaluation of xenon photocoagulation.

An abnormal increase in the permeability of the outer blood-retinal barrier was induced in the eyes of adult pigmented rabbits after retinal xenon arc photocoagulation. The alteration of the blood-retinal barrier, which was assessed by vitreous fluorophotometry after systemic administration of sodium fluorescein, followed a well-defined pattern. Higher values, which were recorded during the fir...

Xenon arc photocoagulation in the treatment of diabetic maculopathy.

New Instrument SEMIAUTOMATED PATTERNED SCANNING LASER FOR RETINAL PHOTOCOAGULATION

The concept of retinal photocoagulation was introduced by Meyer-Schwickerath for the treatment of diabetic retinopathy in the 1950s and used with some success in the 1960s. The xenon arc photocoagulator utilized for this purpose was large, polychromatic, inefficient, and difficult to operate, prompting a search for a better method of treatment. Further progress was achieved when ruby,1 argon io...
