Drainage of Suprachoroidal Fluid Using Silicone Oil Tamponade in Rhegmatogenous Retinal Detachment with Choroidal Detachment.

Purpose

To evaluate a novel silicone oil-assisted technique for managing rhegmatogenous retinal detachment with choroidal detachment (RRDCD), addressing the challenges of incomplete suprachoroidal drainage and postoperative tamponade insufficiency.

Methods

Twelve consecutive RRDCD eyes underwent vitrectomy with controlled silicone oil injection combined with quadrant-by-quadrant sclerotomy compression. The standardized protocol included: (1) pars plana BSS injection for stabilization; (2) 23/25-gauge trocar placement in shallowest quadrants; (3) lighted pick-assisted cannula positioning; and (4) pressure-regulated oil infusion with active fluid displacement.

Results

The mean visual acuity improved from 2.08±0.61 logMAR preoperatively to 1.20±0.94logMAR postoperatively, corresponding to a gain of approximately 24-25 ETDRS letters. Intraocular pressure (IOP) normalized from 5.00 ± 2.05 mmHg to 11.92 ± 2.02 mmHg. All cases achieved complete anatomical success (retinal/choroidal reattachment) with optimal silicone oil fill. Secondary procedures (oil removal with phacoemulsification and IOL implantation) were successfully performed at 3-6 months. No complications occurred during the follow-up period.

Conclusion

This technique provides effective, reproducible management of RRDCD through simultaneous pressure control and active drainage.
