Modification of human platelet behaviour in diabetes.

Among the different factors which could be responsible for the retinal vascular disturbances in diabetic retinopathy, we have investigated platelet populations, sialic acid content of platelets and collagen-induced platelet aggregation. The following results were obtained: a) there was no modification of platelet population distribution except for population A; b) there was a modification of collagen-induced platelet aggregation; the lag time was increased in diabetics.

Computer analysis of ocular results following selective blockade of growth-hormone in diabetic retinopathy. A collaborative study.

Computer storage and analysis of ocular data (visual acuity, fundus photographs and fluorescein angiographies) in diabetic retinopathy (DR) was used before and 1, 3 and 5 years after "Stereo-GIHF". This radiobiological procedure results in the selective inhibition of growth-hormone (GH) release. A series of 107 eyes were analyzed after division into 2 categories A and B (A: progressing background DR, n = 53, B: proliferative DR, n = 54). All patients treated by laser photocoagulation before and/or after stereo-GIHF were excluded from the present study; in contrast complications that impair visual acuity (VA), mainly vitreous hemorrhages, diabetic maculopathy and cataracts, were not discarded. In groups A and B, mean VA was stable showing no significant differences before and 5 years after treatment. In both groups microaneurysms are improved or stable in all cases. Hard exudates were improved in 66% of cases. In group B preretinal new-vessels and neovascularisation on the disc are improved or stable in 90% of cases. The same percentage is observed for extramacular and macular transudations 3 years after Stereo-GIHF. The present data strongly suggest that the selective suppression of GH improves the prognosis of DR. However the prognosis for vision remains poor in macular degenerations; in addition a rapid evolution of new-vessel formations should indicate a combined treatment with argon laser photocoagulation.
