Figure 2: Intra-operative photo showing peri-papillary leakage of trypan blue in an 82 year old male who presented with worsening vision of the right eye due to a total retinal detachment. Intra-operative indented search did not identify any peripheral or equatorial breaks so a modified sequence of DE-TECH was employed. Prior to PFCL, aspiration at the disc revealed blue-stained schlieren. This confirmed the location of a peripapillary hole, masked by a steep staphyloma and peripapillary atrophy. This case demonstrates the utility of DE-TECH for detecting occult posterior breaks as well as the importance of checking at the disc either before or after introducing PFCL.
