VISIONBLUE
Clinical safety rating: caution
Comprehensive clinical and safety monograph for VISIONBLUE (VISIONBLUE).
Visionblue (trypan blue) is a dye that selectively stains the anterior lens capsule and vitreous, enhancing visualization during ophthalmic surgeries such as cataract extraction and vitrectomy. It does not exert pharmacological activity but acts as a vital stain.
| Metabolism | Visionblue is not metabolized; it is cleared from the eye via aqueous humor outflow and systemic absorption is negligible. |
| Excretion | Primarily eliminated unchanged via renal glomerular filtration; minimal biliary excretion (<5%). |
| Half-life | Approximately 2.5 hours in patients with normal renal function; prolonged in renal impairment (up to 12 hours). |
| Protein binding | Negligible (<5%), primarily to albumin. |
| Volume of Distribution | 0.2 L/kg, reflecting confinement to extracellular fluid and minimal tissue binding. |
| Bioavailability | Not applicable for systemic routes; intraocular administration yields direct local effect. |
| Onset of Action | Intraocular administration: immediate staining of anterior lens capsule upon contact. |
| Duration of Action | Staining persists for 10-15 minutes during cataract surgery; eliminated from the eye within 24 hours. |
| Molecular Weight | 894 |
0.5 mL of 0.025% solution intracameral injection (single use).
| Dosage form | SOLUTION |
| Renal impairment | No dosage adjustment required; VISIONBLUE is not systemically absorbed. |
| Liver impairment | No dosage adjustment required; VISIONBLUE is not systemically absorbed. |
| Pediatric use | Safety and efficacy not established in pediatric patients; no standard dosing available. |
| Geriatric use | No specific adjustment; use adult dosing as indicated. |
| 1st trimester | No well-controlled studies in pregnant women; consider risk vs benefit. |
| 2nd trimester | Use only if clearly needed; systemic absorption minimal. |
| 3rd trimester | Use only if clearly needed; no known fetal risk. |
Clinical note
Comprehensive clinical and safety monograph for VISIONBLUE (VISIONBLUE).
| Placental transfer | Not studied; low molecular weight suggests potential for transfer but limited by rapid ocular clearance. |
| Breastfeeding | Not known if excreted in human milk; caution advised due to potential for infant absorption. |
| Lactation Rating | L3 (Moderately Safe) |
■ FDA Black Box Warning
None
| Serious Effects |
Hypersensitivity to trypan blue or any component
| Precautions | Intraocular use only; do not inject intravenously, Potential for corneal endothelial toxicity if excessive volume or prolonged contact, May cause transient increase in intraocular pressure, Hypersensitivity reactions have been reported, Use with caution in patients with compromised corneal endothelium |
| Food/Dietary | No known food interactions. This drug is administered intraocularly and is not ingested; systemic absorption is negligible. |
| Clinical Pearls |
Loading safety data…
| Teratogenic Risk | No teratogenic effects in animal studies; limited human data. Avoid use in pregnancy unless benefits outweigh risks. |
| Fetal Monitoring | Standard prenatal care; no specific monitoring required. |
| Fertility Effects | No evidence of reproductive toxicity; no impact on fertility. |
| VisionBlue (trypan blue ophthalmic solution 0.06%) is a vital dye used as a surgical aid in cataract surgery for staining the anterior capsule during capsulorhexis. It selectively stains the anterior lens capsule due to its affinity for basement membranes, facilitating visualization in eyes with poor red reflex (e.g., white cataracts, dense brunescent cataracts). Avoid injecting into the vitreous; if encountered, perform anterior vitrectomy immediately. Use with caution in patients with pseudophakic or aphakic eyes due to risk of dye retention in the vitreous. Discard any unused solution after surgery; single-use vial only. |
| Patient Advice | This medication is used during eye surgery to help your surgeon see the lens capsule clearly. · It is not self-administered; it will be applied by your surgeon during the procedure. · Inform your surgeon about any allergies, especially to dyes or medications. · Report any eye pain, redness, or vision changes after surgery immediately. · You may experience temporary blue discoloration of the eye, which resolves within days. |
