Tissueblue - Brilliant Blue G injection, Solution prescribing information
Indications & Usage
TissueBlue 0.025% is indicated to selectively stain the internal limiting membrane (ILM).
Dosage & Administration
TissueBlue 0.025% is carefully injected into the Balanced Salt Solution (BSS)-filled vitreous cavity using a blunt cannula attached to the pre-filled syringe, without allowing the cannula to contact the retina or allowing TissueBlue to get under the retina. Sufficient staining is expected within a few seconds. Following staining, all excess dye should be removed from the vitreous cavity.
Dosage forms & Strengths
TissueBlue (Brilliant Blue G Ophthalmic Solution) 0.025% is a clear, bright blue, single-dose ophthalmic solution supplied in 2.25 mL syringes pre-filled to a volume of 0.5 mL.
Use in specific populations
Pregnancy
Risk Summary There are no available data on the use of TissueBlue 0.025% in pregnant women to inform a drug associated risk. Systemic absorption of TissueBlue 0.025% in humans is expected to be negligible following intravitreal injection and subsequent removal of the drug at the completion of surgical procedures. Due to the negligible systemic exposure, it is not expected that maternal use of TissueBlue 0.025% will result in fetal exposure to the drug.
Adequate animal reproduction studies were not conducted with TissueBlue 0.025%.
Lactation
Risk Summary No data are available regarding the presence of Brilliant Blue G in human milk after intraocular administration of TissueBlue 0.025%, or the effects on the breastfed infant or the effects on milk production. However, breastfeeding is not expected to result in exposure of the child to Brilliant Blue G due to the expected negligible systemic exposure of BBG in humans following intravitreal injection and subsequent removal of the drug at the completion of surgical procedures.
Pediatric use
The safety and effectiveness of TissueBlue 0.025% in pediatric patients has not been established.
Geriatric use
No overall differences in safety or effectiveness were observed between elderly and younger adult patients.
Contraindications
None
Warnings and Precautions
Excessive Staining Excess TissueBlue 0.025% should be removed from the eye immediately after staining.
Use of the Syringe Make sure the plunger moves smoothly before injecting the solution. Do not use the product if the plunger does not move smoothly to prime the cannula.
Adverse Reactions
Adverse reactions that have been reported in procedures that included the use of Brilliant Blue G Ophthalmic Solution have often been associated with the surgical procedure. These complications include retinal (retinal break, tear, hemorrhage, and detachment) and cataracts.

Molecular formula: C 47 H 48 N 3 NaO 7 S 2
Clinical Pharmacology
Mechanism of action
Brilliant Blue G has been shown to selectively stain the ILM, but not the epiretinal membrane nor the retina, making it easier to visualize the membrane for removal, although the exact mechanism of this selectivity has not been elucidated.
Nonclinical toxicology
Nonclinical toxicology
Studies to evaluate the potential for carcinogenicity or impairment of fertility of TissueBlue 0.025% have not been conducted. Brilliant Blue G was not mutagenic in the Ames assay, the in vitro mouse lymphoma assay, or the in vivo rat micronucleus assay.
