[A study on treatment of retinal detachment with unseen retinal breaks]

64 cases (66 eyes) of retinal detachment in which no breaks can be found were treated with pars plana vitrectomy, scleral buckling or encircling procedures. The selection of operation depended on the shape and size of retinal detachment, the position of peripheral retinal lattice degeneration, phakia or aphakia, traumatic situation and the appearance of proliferative vitreoretinopathy. The results showed that the detached retina was successfully reattached in 53 eyes (80.3%), 4 eyes were improved (6%), only 9 eyes failed (16.7%). The technic of operation and application are discussed. We consider that suitable active surgical treatment for this kind of cases is encouraging.
