Summary
External drainage of subretinal fluid during rhegmatogenous retinal detachment repair is safe and effective, achieving a 97% success rate in a recent study. Further research is recommended for this promising technique.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Rhegmatogenous retinal detachment (RRD) is a sight-threatening condition requiring surgical repair.
- External drainage of subretinal fluid is a technique used in RRD repair.
Purpose of the Study:
- To evaluate the safety and efficacy of RRD repair using external subretinal fluid drainage.
- To assess outcomes with the 28-gauge External Drainage and Depression device.
Main Methods:
- Retrospective review of 83 patients undergoing primary RRD repair.
- Procedures included scleral buckle, pars plana vitrectomy, or combined surgery with the drainage device.
- Data collected from August 2018 to March 2020 by four surgeons.
Main Results:
- High single operation success rate of 97% (57/59) at 6-month follow-up.
- Favorable safety profile with minimal complications: two subretinal hemorrhages (<2 DD).
- No retinal incarceration; low rates of recurrent RD (2%) and new epiretinal membranes (10%).
Conclusions:
- External drainage of subretinal fluid in RRD repair shows a good safety profile.
- The technique achieves a high single operation success rate.
- Further investigation into the role of external drainage in RRD repair is warranted.
