title: [Fluorescence angiography as a basis for successful prophylactic and therapeutic light coagulation for diabetic retinopathy (author's transl)].
abstract: The fluorescence angiogramme served as a basis for the plan of treatment and as a criterion of treatment success in 192 patients with  diabetic retinopathy who underwent xenon-light coagulation between January 1971 and October 1972. In 64 patients this success could be statistically evaluated comparing the untreated partner eye according to the exact Fisher-test. The rate of success of light coagulation showed itself to be statistically highly significant (p less than 0.01%) with regard to retinal morphology and haemodynamics, but with regard to visual acuity only statistically barely significant (p less than 5%). For the influencing of the capillary occlusion process with light coagulation no statistical significance (p = 25.19%) was found, and for the influencing of the capillary permeation disturbances with light coagulation a slight statistical significancing of the capillary permeation disturbances with light coagulation a slight statistical significnace (p less than 5%) was calculated. For avoiding or hindering present or threatened new vessel formation with light coagulation we calculated a statistical significance of p less than 1%.
