Dosing and uses of BioGlo, Fluorets (fluorescein ophthalmic)
Adult dosage forms and strengths
ophthalmic strips
- 0.6mg
- 1mg
solution, injection
- 10%
- 25%
Eye Examination
Diagnostic staining
- Ophthalmic strips are indicated for staining the anterior segment of the eye during eye examinations
- Moisten by applying 1-2 gtt sterile isotonic irrigation solution, sterile water, or other ophthalmic solution
- Application: While patient looks down, stroke applicator tip across bulbar conjunctiva for fornix; then have patient blink several time
- Alternative application methods include having patient close lid tightly over strip until desired amount of staining occurs for exam
Ophthalmic angiography
- If allergy reaction a possibility, use an intradermal test dose of 0.05 mL; evaluate 30-60 min following intradermal injection; a negative test dose does not exclude potential for allergic reaction; immediate treatment for anaphylaxis, including epinephrine 1:1000 should be available during the procedure
- Intravenous
- May administer using a 23 gauge needle attached to small syringe; take steps to ensure needle has not extravasated prior to turning off room light
- Administer 500 mg as single dose IV into antecubital vein; in cases where a highly sensitive imaging system used (eg, scanning laser ophthalmoscope), may administer a dose of 200 mg; inject dose into antecubital vein over 5-10 sec; luminescence appears 7-30 sec following injection; maintain venous access following procedure in event treatment is needed for anaphylaxis
- Oral (off-label)
- Administer 1 g of injection solution orally; clarity of photographs reportedly poorer than photographs obtained following IV administration

Warnings
Contraindications
Hypersensitivity to components or mercury-containing compounds; history of hypersensitivity to fluorescein sodium
Cautions
Severe local tissue damage, including phlebitis, skin sloughing, toxic neuritis, may occur from extravasation; use caution; discontinue immediately if extravasation occurs
Use caution in patients with history of hypersensitivity, allergies, or asthma
Skin may turn yellow within few minutes of administration and fade in 6-12 hr; urine may appear bright yellow for 24-36 hr
Not for intrathecal or arterial administration
Nausea and/or vomiting and gastrointestinal distress may occur commonly within few minutes following injection; may subside within 10 min
Remove contact lenses before use to avoid staining; after exam, flush eye with saline eye drops and wait at least 1 hr before reinserting contact lenses
Pregnancy and lactation
Pregnancy category: C
Lactation: Excreted into breast milk; American Academy of Pediatrics classifies fluorescein as compatible with breast-feeding
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
