  • B-scan ultrasonic and ultrasound biomicroscopic imaging of retinal detachment

    Purpose To verify the effectiveness of combined B-scan ultrasonoscopy and ultrasound biomicroscopy(UBM)imagings in diagnosis of retinal detachments. Methods To contrast the manifestations in vitrectomy operations with the findings of preoperative combined B-scan ultrasonic and UBM examinations in 25 eyes of 25 cases in which 18 eyes with rhegmatogenous retinal detachment and 7 eyes with traumatic retinal detachment were included. Results B-scan ultrasonic imagings were divided into four types: type C,type V,type upsilon; and type gamma;,which included 6 eyes,2 eyes,4 eyes and 11 eyes respectively,and from type C to type gamma;,the retinal detachments manifested themselves from simple posterior segment proliferative vitreoretinopathy(PVR)to both anterior and posterior PVR.The imagings of UBM were divided into 3 types:shallow retinal detachment,retinal circumferential contraction and retinal anterior displacement,which reflected the degree of anterior PVR from lightness to severeness. Conclusions The technique of combined B-scan ultrasonoscopy and UBM can be used to access the severity of the retinal detachments,hence would be beneficial in diagnosing anterior and posterior PVR,designing the surgical precedures and assessing the prognosis. (Chin J Ocul Fundus Dis,1998,14:16-20)

  • IATROGENIC RETINAL BREAKS IN MICRO-VITREORETINAL SURGERY

    PURPOSE:To investigate the cause and treatment of iatrogenic retinal breaks(lRB)in microvitreoretinal surgery. METHODS:The causes and treatments of 40 iatrogenie retinal breaks of 24 cases in micro-vitreoretinal surgery from July1994 to March 1996 in our department were analyzed retrospectively. RESULTS:40 IRB were found in 24 eyes,among them there were 16 eyes of proliferative vitreoretinopathy(PVR),5 eyes of taumatic PVR and 3 eyes of tractional retinal detachment, The treatments of IRB included scleral cryotherapy ,silicone band buckling,endodiathermy,intraocular tamponade and postoperative argon laser. The IRB of inferior retina and posterior Io scleral buckling acounded for 70% and 92% respectively. The total retinal and macular attachment were 17 eyes and the visual acuity of 19 eyes improved to 0.02 or better during the mean follow up periods of 5 months. CONCLUSION:The IRB is a severe complication in micro-vitrecretinal surgery and has to be obliterated either intraoperatively or postoperatively. (Chin J Ocul Fundus Dis,1997,13: 19-21 )
