Summary
The novel Pneumatic Cryo Explant (PaCE) technique successfully induced subretinal fluid absorption in 90.9% of primary rhegmatogenous retinal detachment cases, avoiding drainage and its complications. This method offers a less invasive approach with significant visual improvement in most patients.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Surgical Innovation
Background:
- Subretinal fluid (SRF) drainage during scleral buckling for rhegmatogenous retinal detachment (RRD) carries potential complications.
- Preoperative induction of SRF absorption can mitigate these risks.
Purpose of the Study:
- To evaluate the efficacy of the Pneumatic Cryo Explant (PaCE) technique in promoting preoperative SRF absorption in primary bullous RRD.
- To assess the need for SRF drainage and the overall success rate of the PaCE procedure.
Main Methods:
- A prospective trial included 22 eyes with primary bullous RRD.
- Intravitreal injection of 0.3 ml C3F8 100% was administered.
- Postoperative positioning, retinopexy (cryo/laser), and scleral buckling (if needed after SRF absorption) were performed.
Main Results:
- SRF absorption was achieved in 20 of 22 eyes (90.9%), eliminating the need for drainage.
- Successful retinal reattachment was observed in 90.9% of cases at 12 months.
- Visual improvement occurred in 95% of patients; one eye experienced vision loss due to total RD.
Conclusions:
- The PaCE technique is a viable alternative for primary RRD, particularly when SRF drainage is considered.
- This method effectively avoids SRF drainage and associated complications.
- PaCE does not impede the success of subsequent surgical interventions.
