[Treatment of diabetic retinopathy. Clinical experience with various lasers. Complications associated with lasers]

Since the ruby laser was first introduced in the early sixties, different types of lasers and different wavelengths have been used to treat diabetic retinopathy. Although longer wavelengths may be preferable in selected cases, different studies were unable to demonstrate significantly different results when diabetic retinopathy or maculopathy was treated with different wavelengths. The quality of the treatment as well as the incidence of complications depend on the technique used and the experience of the treating ophthalmologist. Some complications such as pain during treatment or vitreous haemorrhage can not always be avoided. Other complications such as a foveal burn are unacceptable. It is also possible by using an appropriate technique to minimize visual field restriction.
