Minims (Fluorescein Sodium)

• Fluorescein Sodium is employed in ophthalmology to highlight ocular surface defects and aid visual assessment.
• Corneal abrasion: Enables visualization of epithelial defects for accurate diagnosis.
• Ocular surface integrity assessment: Stains damaged epithelium to evaluate healing after surgery or trauma.
• Fluorescein staining for ophthalmic examinations: Facilitates detection of foreign bodies and tear‑film abnormalities under cobalt‑blue light.

• Fluorescein sodium binds to proteins and cellular debris on the ocular surface, producing a bright yellow‑green fluorescence when illuminated with cobalt‑blue light. This contrast highlights areas of epithelial loss or disruption, allowing clinicians to detect corneal abrasions, ulcerations, and other surface abnormalities during slit‑lamp examination.

Fluorescein Sodium may cause ocular and systemic reactions, most of which are mild and transient.

Common Side Effects

• Transient eye irritation: mild burning or stinging upon instillation.
• Temporary blurry vision: visual disturbance lasting a few minutes.
• Mild conjunctival redness: slight redness of the eye.
• Allergic conjunctivitis: itching and redness in sensitive individuals.

Serious or Rare Side Effects

• Severe allergic reaction: anaphylaxis or angioedema requiring immediate medical attention.
• Corneal toxicity: persistent epithelial defect or ulceration with improper use.
• Systemic hypersensitivity: rash, urticaria, or respiratory distress.
• Increased intraocular pressure: rare elevation noted in susceptible patients.

• When using Fluorescein Sodium, consider the following precautions to ensure safe and effective application.
• Allergy assessment: verify no known hypersensitivity to fluorescein or related compounds.
• Contact lens wearers: remove lenses before application to avoid staining and discomfort.
• Pregnancy and lactation: use only if clearly needed, as safety data are limited.
• Concurrent ocular medications: avoid mixing with other eye drops unless directed by a clinician.
• Eye injury: do not apply to a ruptured globe or active infection without professional guidance.
• Store at ambient temperature: keep below 25 °C, protect from light and moisture in original container.

Fluorescein Sodium can interact with certain ophthalmic agents and systemic medications.

Major Interactions (Avoid)

• Topical anesthetics: may increase corneal toxicity when combined.
• Anticholinergic eye drops: can reduce fluorescein staining quality.
• Systemic sulfonamides: rare cross‑reactivity leading to hypersensitivity.

Moderate Interactions (Monitor Closely)

• Contact lens solutions: may cause staining artifacts; monitor visual clarity.
• Other diagnostic dyes: overlapping fluorescence can interfere with interpretation.
• Systemic antihistamines: may diminish allergic response signs.
