An analysis of heavy silicone oil treatment for inferior proliferative vitreoretinopathy
Purpose: Proliferative vitreoretinopathy (PVR) is a complication of retinal detachment which requires multiple vitreoretinal surgical interventions and frequent use of oil endotamponade.

| description | Purpose: Proliferative vitreoretinopathy (PVR) is a complication of retinal detachment which requires multiple vitreoretinal surgical interventions and frequent use of oil endotamponade. In this study, we conducted an in-depth analysis of complications associated with the use of heavy silicone oil in the management of inferior PVR. Methods: A retrospective cohort study of 20 eyes that underwent vitrectomy for inferior PVR with use of heavy silicone oil (Densiron 68) between March 2021 and October 2022 at Oxford Eye Hospital. Complications were classified into major categories relating to intraocular pressure, inflammation, lens, and oil emulsification/migration. Visual outcomes and surgical success rate were also evaluated. Results: Fill-induced pressure spikes (> 30 mmHg) within 14 days post-surgery were common after Densiron tamponade, especially in patients previously on glaucoma drops. The number of glaucoma drugs were increased in 45% of patients during Densiron tamponade. In 20% of cases, an increased medication was continued long-term after Densiron removal. Significant cataract progression occurred in all phakic patients. In 25% of pseudophakic cases, posterior capsule opacification was noted. Inflammatory complications, such as anterior uveitis, were rare and any cystoid macular oedema was transient. No unexplained acute loss of vision following Densiron removal was encountered. The anatomical success rate at 30 days after Densiron removal was 70%. The mean (± SD) best-corrected visual acuities were 1.04 (± 0.79), 0.85 (± 0.62) and 0.50 (± 0.51) logMAR prior, during and after Densiron tamponade, respectively. Conclusion: The outcomes in this cohort treated with Densiron 68 were comparable to previously reported anatomical and functional results in cases with inferior PVR. IOP and lens-related complications require additional treatment during or after Densiron tamponade. Inflammatory complications rarely occurred over tamponade durations of around three months. Trial registration: Analyses were conducted as an internal quality improvement audit and as such did not require external IRB review. |
