Clinical analysis of recurrent retinal detachment after silicone oiI removal

Objective To explore the main causes and influencing factors of recurrent retinal detachment after silicone oiI removal. Methods Retrospective analysis was performed on the clinical data of 365 patients (368 eyes) caused by retinal detachment in our department from January 2008 to January 2016. All patients underwent removal of silicone oil after vitrectomy combined with silicone oil tamponade. Results Retinal re-detachment occurred in 24 patients (24 eyes, 17.65%) from January 2008 to December 2011, in 18 patients (18 eyes, 7.76%) from January 2012 to January 2016. Most recurrent retinal detachment occurred in 4 week. Among these retinal re-detachment in 42 eyes, residual peripheral vitreous 8 eyes, traction of epiretinal proliferative membrane 9 eyes, new retinal hole 7 eyes, activated original retinal holes 6 eyes, non-closure of original retinal holes 9 eyes and traction of retinal incarceration in the sclera incision 3 eyes. Conclusions Operative skill and level of proficiency of operator is the main influ-encing factor of recurrent retinal detachment after silicone oil removal, it is very important to improve operative skill. It should pay attention to follow-up clinic, going over the retina during silicone oil removal. Sometimes, intraocular laser photocoagulation or frozen or combined seleral buckling surgery is necessary. Key words: Retinal detachment; Silicone oil removal; Recurrence
