Chromophore-Assisted Retinal Break Detection to Manage Challenging Situations in Retinal Detachment Redo Surgery.

Introduction: The purpose of this case series is to demonstrate that subretinal blue dye injection, with and without 180-degree endolaser retinopexy, can be considered a useful tool in finding occult rhegmatogenous retinal breaks in eyes with recurrent retinal detachment. . Three patients with recurrent retinal detachment were treated between January and March 2018. In all cases, the intraoperative internal search did not demonstrate any obvious break or hole. MembraneBlue-Dual (Trypan Blue 0.15% + Brilliant Blue G 0.025% + 4% PEG) was then injected into the subretinal space using a 41-gauge cannula. The eye was rotated such that the dye was pushed through a tiny break which was causing the retinal detachment. 180-degree laser retinopexy was performed on a single eye. After silicon oil removal and absorption of the gas tamponade, retinas remained attached at three-months follow-up.

Conclusions: Chromophore-assisted occult retinal break detection can be considered a useful but not risk-free surgical technique in managing some unexpected and challenging intraoperative situations.
