Fluor-I-Strips A.T.
Fluor-I-Strips A.T. are fluorescein sodium strips used for diagnostic purposes in ophthalmology. They are primarily employed to detect corneal abrasions, foreign bodies, and other ocular surface disorders. The fluorescein dye in these strips fluoresces under blue light, allowing healthcare professionals to visualize abnormalities on the surface of the eye.

What should I do if I accidentally touch the strip to my fingers?
If the strip is contaminated, do not use it. Always use a new strip to ensure accurate results.
Is there any special equipment needed to visualize the fluorescein?
Yes, a blue light source, such as a Woods lamp or cobalt blue filter, is required to visualize the fluorescein properly.

Comprehensive Drug Guide
How Does Fluor-I-Strips A.T. Work?
The fluorescein dye in Fluor-I-Strips A.T. binds to damaged epithelial cells of the cornea and conjunctiva. When exposed to a blue light (Woods lamp or cobalt blue filter), the fluorescein fluoresces bright green, highlighting any abrasions or foreign bodies on the ocular surface, thereby assisting in diagnosis.
Common Dosages
The typical dosing for Fluor-I-Strips A.T. involves:
- Application: One fluorescein strip is moistened with a sterile saline solution or artificial tears and then applied to the conjunctival sac or the surface of the eye, as directed by a healthcare provider. The fluorescein can then be visualized using a blue light.
Typical Dosing
FDA Approved Indications
- Detection of corneal abrasions and foreign bodies.
- Assessment of tear film stability and ocular surface conditions.
Who Shouldn't Take Fluor-I-Strips A.T.?
- Hypersensitivity: Known hypersensitivity to fluorescein sodium or any of its components.
- Severe Eye Infections: In cases of severe ocular infections, as the use of fluorescein may exacerbate the condition.
Advice From The Pharmacist
- How to Use: Ensure proper technique when applying the strip to avoid contamination and ensure accurate results. Follow the healthcare provider’s instructions for application and visualization.
- Monitor Symptoms: If experiencing increased eye pain, redness, or changes in vision after use, contact a healthcare provider immediately.
- Storage: Store at room temperature and protect from light. Ensure the packaging remains sealed until use to maintain sterility.
