A Comparison of the Posterior Vitreous Detachments in Normal and Diabetic Retinopathy

ABSTRACT

Among the panents who visited Ewha Womens Universty Hospital from Dec 1988 to Oct 1989, the authors investigated the presence of posterior vitreous detachment(PVD) in 181 eyes Wlth nomal fundus flnd1ngs and 160 eyes wlth diabetic retinopathy. In normal eyes, the incidence of complete PVD increased with age but that of partlal PVD was not related to age. In non prolderative diabetic retinopathy, complete PVD was 15.6% and partial PVD was 5.6%, And in proliferative diabetic retinopathy, complete PVD was 8.6% and partial PVD was 41.4%. It is suggested that there is a close relationship between proliferative diabetic retinopathy and partial PVD.
