BACKGROUND: 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. CASE PRESENTATION: 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. Membraneblu-dual (Trypan Blue 0,15% + Brilliant Blu 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. A 180 degree laser retinopexy was performed on a single eye. After silicon oil removals and absorption of the gas tamponade respectively, retinas remained attached at three months follow up. CONCLUSIONS: Chromophore assisted occult retinal break detection can be considered a useful and safe surgical technique in managing some unexpected and challenging intraoperative situations.
