Perfluorodecalin Versus Densiron 68 Heavy Silicone Oil in the Management of Inferior Retinal Detachment Recurrence.

Background And Objective: To assess the efficacy of perfluorodecalin (PFD) or Densiron 68 heavy silicone oil (HSO) in the management of inferior complex retinal detachment recurrence.

Patients And Methods: A retrospective, comparative consecutive case series study. Twenty-four eyes of 24 patients affected by inferior complex retinal detachment recurrence underwent pars plana vitrectomy with PFD or HSO as endotamponade. All patients recruited were affected by complicated inferior retinal detachments and had already undergone at least one vitreoretinal procedure. The primary endpoint was anatomical success with primary and secondary surgery. The secondary endpoints were functional outcome and inflammatory complications.

Results: Out of 24 cases of inferior retinal detachment recurrence, 12 were tamponed with PFD (PFD group) and 12 with HSO (D68 group). Retinal reattachment rate at first surgery was 50% for the D68 group and 66.6% for the PFD group. Final reattachment rate after two or more surgical operations was 91.6% for the PFD group and 83.3% for the D68 group. Best-corrected visual acuity improved in both groups from a mean of 1.00 logMAR (20/200; standard deviation [SD]: 1) to 0.60 logMAR (20/80; SD: 0.3), and from a mean of 1.81 logMAR (20/2000; SD: 1.1) to a mean of 2.00 logMAR (20/2,000; SD:1) for the PFD and D68 groups, respectively.

Conclusion: Both the endotamponades used showed good results in solving inferior retinal detachment recurrence with a slightly better rate in the PFD group, but it was not statistically significant (P > .05). [Ophthalmic Surg Lasers Imaging Retina. 2019;50:274-280.].
