Macular toxicity following brilliant blue G-assisted macular hole surgery - a report of three cases.

INTRODUCTION Brilliant blue G is a new dye used for staining the internal limiting membrane to ease its peeling in cases like a macular hole. CASES Three patients presented with full-thickness idiopathic macular hole. They underwent pars planavitrectomy, Brilliant Blue G (BBG) stained internal limiting membrane peeling and fluid gas exchange. OBSERVATIONS Postoperatively,the macular hole closed but foveal thinning and perifoveal hyperpigmentation presumably due to BBG toxicity were observed in all three patients. All of them had a subnormal final best corrected visual acuity. CONCLUSION This case series highlights the unusual occurrence of macular toxicity following brillantblue G-assisted macular hole surgery.
