Abstract
Sixty-five patients without apparent retinopathy and 38 normal controls were examined by ocular fluorophotometry.
As regards the mean fluorescein concentration in the diabetics at one and two hours after intravenous dye injection, only the lenticular autofluorescence was statistically significantly higher compared to the normal controls. The variance in diabetics was larger in the retina, the vitreous, and the anterior chamber than in normals. The ratio of subjects showing a fluorescein concentration in the posterior vitreous of more than M±2 s. d. (the mean value and standard deviation of the normals) appeared to be significantly higher in the diabetics.
There were no significant differences among the diabetic subgroups classified according to the duration of the disease, blood glucose control, blood pressure, or plasma lipid concentration.
