Short-term outcomes of heavy silicone off tamponade in vitreoretinal surgery for complicated retinal detachment

Objective To observe the therapeutic effect and safety of heavy silicone oil used as internal tampenade to treat com- plicated retinal detachment.Design Retrospective cases series.Participants 16 patients(16 eyes)with complicated retinal detachment. Methods Intraocular tamponade of heavy silicone oil and vitreoretinal surgery were used in all patients,and retinotomy,per-fluorocar- bon liquid infusion,laser photocoagulation,phacoemulsification with intraocular lens implantation were performed in some patients. Main Outcome Measm-es Retinal status,visual function,intraocular pressure.Result The mean follow-up was 15.1±8.48 weeks(range from 3 to 28 weeks).Retinal reattached and holes were closed in 15 cases(93.8%).Heavy silicone oil was taken out 1 to 3 months after operation in 13 patients.Heavy silicone oil was retained in the other 3 patients at the last visit.Only one of 16 patients was found with local detachment near retinal hole and pneumatic retinopexy was performed after oil was taken out.All the cases appeared different ex- tent of lens opacity,mainly at posterior lens capsule.After surgery intraoeular pressure was normal in all except 4 cases with temporary high pressure.Conclusion The study shows that heavy silicone oil tampenade is effective to treat complicated retinal detachment with tears located lower than 10-2 o′clock or presented homolaterally.Its main side-effect is complicated cataract.
