Long-term outcomes of Oxane Hd as intraocular tamponade in the treatment of complicated retinal detachment

Abstract

Background: To evaluate the efficacy and safety of heavy silicone oil Oxane Hd as intraocular tamponade in the treatment of complicated retinal detachment (RD).

Methods: Forty eyes of 40 patients with complicated RD were recruited for this prospective study. Inclusion criteria were proliferative vitreoretinopathy grade > or = CP2, mainly inferior and posterior retinal breaks, or superior retinal breaks with patient's inability to posture. Oxane Hd was used as intraocular tamponade. The retinal status, the best-corrected visual acuity (BCVA) results, and any complications were observed.

Results: The mean duration of Oxane Hd endotamponade was 87.9 +/- 10.4 days, and the mean follow-up time after Oxane Hd removal was 438.1 +/- 153.7 days. The primary anatomical success rate after Oxane Hd removal was 87.5%, and with further intervention 97.5%. The BCVA significantly improved, from mean logMAR 2.12 +/- 0.60 to 1.38 +/- 0.59 (P < 0.001). The postoperative complications included temporary inflammatory reaction, moderately high intraocular pressure, heavy silicone oil emulsification, lens opacity and retinal proliferative membranes.

Conclusions: Without a requirement for postoperative prone position, heavy silicone oil Oxane Hd is effective and safe for the treatment of complicated RD with inferior and posterior breaks. Larger groups and a longer follow-up period will be included to further evaluate the efficacy with Oxane Hd in superior retinal breaks.
