C20H10Na2O5 Fluorescein Sodium Ophthalmic Strips

What is this medication? Fluorescein Sodium Ophthalmic Strips are a diagnostic tool used by eye care professionals to identify issues on the surface of the eye. These strips contain a specialized dye that glows bright green under cobalt blue light. When applied to the eye, the dye adheres to damaged areas of the cornea or conjunctiva, making it easier for a doctor to see scratches, ulcers, or foreign objects that would otherwise be invisible to the naked eye.

Beyond identifying injuries, these strips are also utilized for several clinical procedures. They are commonly used during tonometry to measure the internal pressure of the eye, which is a key part of screening for glaucoma. Additionally, the strips help optometrists evaluate the fit of rigid contact lenses by showing how tears flow beneath the lens. The dye is temporary and typically washes away naturally with tears shortly after the examination is complete.
