Objective To present stereoscopic image of rhegmatogenous retinal detachment with three-dimentional reconstruction of sonography． Methods Ultrasound data were collected by Hpsonos 1500 and 7.0MHz transducter with the motor controlled by computer．Three-dimentional image were reconstructed with Tomtec echoscan． Results Three-dimentional image were successfully reconstructed in 14 eyes of 13 cases of retinal detachment include 3 eyes of 3 cases with opaque refractive medium showing stereosopic image of retina and some retinal tears． Conclusion Static three-dimentional reconstruction of sonography might enhance the ability to visulize spatial anatomic structure of retina and offer a new method to find retinal tears in patients with opague refractive medium． (Chin J Ocul Fundus Dis,1998,14:24-25)
PURPOSE：To search for the treatment of recurrent detachment of retina with severe proliferative vitreretinopathy(PVR) by vitreoretinal surgery. METHODS:Fourty-seven cases of recurrent detachment of retina with severe PVR treated by vitrectomy between September 1987 and Noverber 1994 were systematically reviewed. RESULTS:On discharge from the hospital,the retina was totally reattached in 30(63.8%)of the 47 cases,partially reattached in 9 cases (19.1%)and still detached in 8 cases(17.1%). CONCLUSIONS:In addition to using the surgical procedures similar to the conventional vitreoretinal surgery,the histopathological change induced by the previous operation in sick eyes should be paid attention to. （Chin J Ocul Fundus Dis,1996,12: 10-12）
