Abstract

Finding a retinal break which is responsible for retinal detachment (RD) is a critical step in the surgical treatment of this condition. Identifying the break which is the source of subretinal fluid (SRF) could pose a challenge especially in complex RDs, re-RDs with extensive laser scars or where there is lack of contrast from the choroid. Two cases of recurrent RD where PVR was not seen, BBG dye was injected into the subretinal space to identify the occult breaks. BBG was loaded in the subretinal injector with lowered infusion pressure and with foot pedal control the dye was injected into the subretinal space. PFCL was used to displace the dye from the subretinal space which emerged via the previously invisible break. To conclude Subretinal BBG dye is useful for occult break detection as it provides a colour contrast, A posterior draining retinotomy can be avoided if break is localised, useful in recurrent RD and where there is lack of contrast from the choroid.
