Summary
Subretinal trypan blue injection successfully identified retinal breaks in 4 of 5 patients undergoing surgery for rhegmatogenous retinal detachment (RD). This chromophore-assisted technique aids in detecting elusive breaks during RD repair.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Retinal Surgery
Background:
- Identifying retinal breaks is crucial for successful rhegmatogenous retinal detachment (RD) repair.
- Standard methods like internal search with scleral indentation may fail to locate all retinal breaks.
Purpose of the Study:
- To evaluate the utility of subretinal trypan blue injection for identifying retinal breaks during vitrectomy for RD.
- To assess the efficacy of chromophore-assisted detection in challenging RD cases.
Main Methods:
- An interventional case series involving five patients with RD where breaks were initially unidentifiable.
- 0.15% trypan blue was injected into the subretinal space via a 41-gauge cannula.
- Perfluorocarbon liquid was used to facilitate visualization and drainage of subretinal fluid through identified breaks.
Main Results:
- Retinal breaks were successfully identified in 4 out of 5 patients using this technique.
- All patients achieved retinal reattachment after surgery.
- Median visual acuity post-operatively was 6/12.
Conclusions:
- Subretinal trypan blue injection is a potentially valuable technique for detecting difficult-to-find retinal breaks during RD surgery.
- Chromophore-assisted detection can improve surgical outcomes in cases of rhegmatogenous retinal detachment.
