Purpose: To evaluate 0.025% brilliant blue G (BBG) for staining the internal limiting membrane (ILM) during vitrectomy.
Methods: In a retrospective, non-comparative clinical case series, we analyzed consecutive 111 patients who underwent pars plana vitrectomy and removal of the ILM after staining using BBG solution. BBG was dissolved and diluted with balanced salt solution at a concentration of 0.025% and then sterilized by filtering through a 0.22 μm millipore filter. The prepared BBG solution was injected into the vitreous cavity over the macula after removal of the vitreous and excessive solution was removed immediately.
Results: The ILM was successfully removed without use of additional adjuvant in all cases. Mean best corrected visual acuity (log MAR) was significantly improved from 0.80 ± 0.44 at baseline to 0.40 ± 0.39 at 6 months postoperatively (p < 0.001). One case each of endophthalmitis and diabetic papillopathy developed. The relationship when using BBG solution was not identified as complications were not observed in the other patients who underwent vitrectomy using the same BBG solution on the same day. One idiopathic epiretinal membrane patient had visual acuity loss more than 2 lines. During the follow-up period, other complications suspected to be associated with the use of BBG solution were not observed.
Conclusions: A BBG solution (0.025%) was effective in staining the ILM for removal. Complications associated with the use of BBG solution were not observed.
