Trypan Blue

Preparations for Ophthalmic diagnosis Prescription

Indications

TyBlue is used during eye surgery to stain the anterior capsule of the lens, helping the surgeon see it more clearly during the procedure.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Trypan Blue is a special dye used to selectively stain the front (anterior) capsule of the eye's natural lens. Because the dye does not pass through this capsule, it clearly outlines the anterior lens capsule, setting it apart from the unstained lens cortex and inner lens material underneath.

Pregnancy & Breastfeeding

Pregnancy Category C. No adequate, well-controlled studies have been done in pregnant women, so Trypan Blue should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus.

Lactation: It is not known whether Trypan Blue passes into human breast milk. Since many drugs do pass into breast milk, caution should be exercised when giving it to a breastfeeding woman.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: Injecting Trypan Blue into the eye is done in two steps. First, a fine 26-gauge needle is used to place a small air bubble in the anterior chamber, which keeps the dye from being diluted by the aqueous humor. Next, using a tuberculin syringe, the dye is injected onto the anterior lens capsule. The staining is considered adequate once the capsule has taken up the dye and contracted. If any part remains unstained, an additional drop can be applied until full staining is achieved.
