Registration Number
NCT01820520
Lead Sponsor
Asociación para Evitar la Ceguera en México
Brief Summary

Study designed to evaluate the safety and efficacy of double staining with brilliant blue G 0.025% as an adjuvant to macular surgery. Patients undergoing surgery for macular hole or epiretinal membrane will be included. Safety will be evaluated by optic coherence tomography, pattern reversal electroretinogram and multifocal electroretinogram.
