By the use of a new online measuring system the effect of argon-laser coagulation
in diabetics on the diameters of retinal arteries was measured. METHOD: The
vessel diameter of retinal branch arteries were measured in patients with type-II
diabetes before and after (0.5 h) argon-laser coagulation. Ten patients without
previous laser treatment were included in this study. Measurements were taken in
all four quadrants by the use of a new automatic online measuring system.
RESULTS: The new technique allowed measurements to be made within an acceptable
period of time and with little strain on patients. After argon-laser coagulation
56.7\% of retinal arteries showed a significant vasodilation. No significant
changes in vessel diameter were found in 18.9\% of these arteries, whereas 24.3\%
showed significant vasoconstriction. CONCLUSION: The new online measuring system
is able to measure the effects of photocoagulation on an individual basis with a
noninvasive technique. The first findings presented here confirm previous studies
of larger groups, with a considerable reduction in efforts required.
