Indications

Fluorescein does not stain a normal cornea but conjunctival abrasions are stained yellow or orange, corneal abrasions or ulcers are stained a bright green and foreign bodies are surrounded by a green ring. Fluorescein can be used in diagnostic examinations including Goldmann tonometry and in the fitting of hard contact lenses

Therapeutic Class

Preparations for Ophthalmic diagnosis

Pharmacology

Fluorescein sodium responds to electromagnetic radiation and light between the wavelengths of 465- 490 nm and fluoresces, i.e., emits light at wavelengths of 520-530 nm. Thus, the hydrocarbon is excited by blue light and emits light that appears yellowish-green. Following intravenous injection of fluorescein sodium in an aqueous solution, the unbound fraction of the fluorescein can be excited with a blue light flash from a fundus camera as it circulates through the ocular vasculature, and the yellowish green fluorescence of the dye is captured by the camera. In the fundus, the fluorescence of the dye demarcates the retinal and/or choroidal vasculature under observation, distinguishing it from adjacent areas/structures.
