A clinical study on heavy silicone oil in the treatment of complicated retinal detachment

Objective To evaluate the therapeutic effect and safety of heavy silicone oil used as interhal tamponade to treat complicated retinal detachment. Methods Vitreoretinal surgery and intraocular tamponade of heavy silicone oil (Oxane HD) were used in 13 patients (13 eyes) with complicated retina detachment. Scleral buckling, epiretinal membrane peeling, retinotomy, per-fluorocarbon liquid infusion, laser photocoagulation, phacoemulsification were performed in some patients. The best-spectacle corrected visual acuity (BCVA), retinal status and complications after surgery were observed. Results The mean duration of heavy silicone oil endotamponade was 93 days and the mean follow-up was 130 days after heavy silicone oil removal. BCVA was improved in 12 cases (92.3%). Retinal reattached and holes were closed in 10 cases with heavy silicone oil endotamponade (77%) in the end of the follow-up. The postoperative complications included moderate high intraocular pressure, temporary inflammatory reaction, lens opacity, fibrocellular membranes proliferation and heavy silicone oil emulsification. Conclusions The heavy silicone oil Oxane HD is effective and safe to treat complicated retinal detachment, especially with holes located in the inferior and posterior pole.
