Abstract

PURPOSE: To report two rare case reports of outer retinal and retinal pigment epithelium (RPE) damage at the macula following brilliant blue G (BBG)-assisted epiretinal membrane (ERM) removal surgery.
METHODS:
Retrospective review of consecutive two cases of macular toxicity.
RESULTS:
Two patients presented with similar history of metamorphopsia and an epiretinal membrane at the macula on OCT with increased central macular thickness. BBG-assisted ERM removal and internal limiting membrane peeling surgery was performed for both the patients. Over the subsequent visits, a well-defined area of outer retinal and RPE alteration was identified on OCT and fundus autofluorescence without any improvement in visual acuity. At 3month follow-up visit, the visual acuity improved in both the cases with decrease in the area of RPE alteration on both OCT and FAF
CONCLUSION:
This case series highlights the unusual occurrence of macular toxicity following brilliant blue G-assisted ERM removal surgery.
