Abstract
The aim of this study is to evaluate vital dyes »Brilliant Blue G« (BBG) and »Membrane Blue Dual« (MBD) for
intraoperative staining of the inner limiting membrane (ILM) during vitrectomy for macular hole (MH). Retrospective,
comparative case series on 18 eyes with macular holes who underwent »23 and 25 gauge« pars plana vitrectomy. Main
outcome measurements were staining intensity and characteristics, visual acuity, visual field, OCT measurements and
complications over a period of 6 months. With the help of BBG and MBD succesfully was removed complete ILM in 14
eyes. Postoperative visual acuity was improved in 12 patients, unchanged in 2 patients and worse in 4 patients. Central
retinal thickness showed significant postoperative reduction with closure of macular hole. OCT values range were from
–10 to –250 mm. No visual field defects and no adverse effects were found. BBG and MBD sucesfully identificate internal
limiting membrane during vitrectomy for MH. Good anatomical and functional results are achieved with the use of both
vital dyes.
