[Role of anterior vitrectomy in the prevention of retinal detachment after vitreous loss].

A study was performed in two series of patients on whom lens extraction was done. Congenital cataracts were excluded from this study. In one series. the closure of the wounds was satisfactory; in the other, large anterior vitrectomy was carried out. The frequency of detachment (about 4%) seems to be approximately the same in the two series, but inflammatory signs and hypertony are more frequent when vitrectomy is not done.
