title: The effect of myo-inositol treatment on basement membrane thickening in the BB/W-rat retina.
abstract: A polyol-pathway related perturbation of myo-inositol metabolism has been invoked in the pathogenesis of diabetic complications, including retinal microvasculopathy. Previous studies have demonstrated a beneficiary effect of aldose reductase inhibition on basement membrane thickening of retinal microvessels in diabetic animals. In the present study we demonstrate a significant but partial effect on basement membrane thickening following myo-inositol supplementation. Qualitative structural changes, such as nodular swellings, fibrillar changes and basement membrane projections were not effected by myo-inositol supplementation, suggesting that although abnormal myo-inositol tissue levels may play a role in basement membrane thickening, other factors may be of primary pathogenetic importance.
