Low-Viscosity Heavy Silicone Oil Endotamponade for Complex Inferior Rhegmatogenous Retinal Detachments

Purpose: To evaluate the use of Densiron Xtra tamponade for inferior and complicated rhegmatogenous retinal detachments (RRD). Methods: A retrospective case series was conducted between January 2019 and December 2023. Cases involving ocular trauma or follow-up of less than 12 months were excluded. Results: The median patient age was 66 years, and 39.5% of the patients were female. All 123 eyes had inferior RRDs; 42.3% had a history of prior retinal detachment, 85.4% had proliferative vitreoretinopathy grade C/D, and 67.5% had macula-off retinal detachments. The mean tamponade duration was 10.4 weeks, and the mean follow-up duration was 16.3 months. Primary and final anatomic success rates were 75.6% and 96.8%, respectively, with a mean logMAR improvement in visual acuity of 0.4 ( P < .001). Complications before oil removal included anterior chamber dispersion (11.4%) and retinal breaks (4.1%). After oil removal, complications included anterior chamber dispersion requiring washout (15.5%), cataract formation (13.8%), posterior capsular opacification (15.5%), hypotony (8.1%), intraocular inflammation (4%), temporary macular thinning (4%), and emulsification (2%). Conclusions: Densiron Xtra tamponade demonstrated excellent anatomic and visual outcomes in eyes with inferior and complicated RRDs, with low complication rates.
