Objective To invesligate the treatment of retinal de tachment(RD) after silicone oil tamponades(SOT)． Methods The records of a consecutive series of 32 eyes with redetachment of retina after SOT surgery between 1998 to 2000 were reviewed retrospectively． The surgical techniques used for these cases included remove of silicon oil,peeling of preretinal membrane, retinotomy, endolaser photocoagutation, secondary vitrectomy and C3 F8 tamponades． Results In 28 of 32 eyes the retina was reattached (87．6%)． The postoperative visual acuity was improved in 12 eyes, redused in 4 eyes and remained no change in 16 eyes． The postop erative complications in 6 eyes included secondary glaucoma(3 eyes), hypotony (1 eye) and hyphema (2 eyes)． Conclusion The techniques of preretinal membrane peeling, retinotomy, endophotocoagulation and C3 F8 tamponades can be effectively used in combination to treat the redetachment of retina after the silicone oil tamponades surgery． (Chin J Ocul Fundus Dis,2001,17:214-215)
