[A study using the computer-controlled perimeter Perimat 206 on the effect of Circo-Maren on visual field defects]

In 1987 an open study was conducted in an ophthalmological practice to test Circo-Maren tablets. Examinations using a computerized perimeter revealed that therapy with Circo-Maren can lead to a reduction in visual field defects in patients with senile macular edema and retinal angiosclerosis. In cases with severe defects, favorable results were achieved which were statistically significant (duration of treatment: 4-12 weeks). Considerable fluctuations in the number and intensity of the defects were seen in the various intermediate examinations.
