RESUMO
Diabetic vitreopapillary traction syndrome (VPT) is a variant of diabetic retinopathy (DR) that can lead to vision loss in advanced stages. This review reports on the biomechanics of the vitreous in the pathogenesis of proliferative DR, in particular diabetic VPT. The article analyzes and summarizes literature data, presents the views of different authors on this problem, and provides the results of Russian and foreign scientific research on this pathology. It is concluded that further research in this area can lead to a significant improvement in the results of therapy, timely diagnosis, and preservation of vision in patients with DR.

By means of computer assisted tomography (CAT) 22 patients with ovarian and 13 with uterus cancer were examined for diagnostic reasons. The results were compared with surgical findings. The advantage of CAT over objective clinical examination was shown particularly in cases where the tumour goes beyond the organ and lymphnodes are affected. In spite of the high information value of the CAT a differential diagnosis is difficult in cases of ovarian cancer. The method is little effective in case of corpus carcinoma in the stage I. In 14 patients with cervix cancer it could be shown, that CAT is inefficient for an early detection of malignant tumours of this localisation. By means of CAT, however, one can get additional information about the spreading of the process, particularly in cases with relatively high localized and not well detectable by bimanuel examination and information to clear up concomitant diseases of pelvic organs as well.
