[Horseshoe tears and proliferative vitreoretinopathy].
Eyes at the risk of developing severe PVR postoperatively are limited to those affected with retinal detachment associated with horseshoe tears. This study is conducted to determine the relationship of horseshoe tears and PVR. 101 failure cases following surgery of retinal detachment with simple horseshoe tears were reviewed. The PVR group was compared with the group without PVR. The results indicate that vitreous gel liquefaction and posterior vitreous detachment are essential reasons of retinal detachment with horseshoe tears. Vitreous hemorrhage, uveitis, choroidal detachment and multiple operations are predisposing factors. It is the clinical evidence developed PVR that horseshoe tears with a curled and fixed posterior edge or the anterior flaps are smaller in size than the area of the exposed pigment epithelial cells.
