Summary
In a double blind study of 5 heparin treated and 5 streptokinase treated patients
with central retinal vein occlusions it would seem from the results based on visual
acuity, ERG and EOG and fluorescence angiography that the heparin treated group were
better off than the SK treated patients.
It therefore seems dubious whether streptokinase therapy affords such an important
advantage over the convential heparin therapy in cases of central retinal vein occlusions.
It must be stressed that a group of 10 patients is very small and that the observations
made are probably not statistically significant.
