Fluresin 600mg Injection is used before eye examinations. It has tissue staining properties. Once injected, it stains the damaged cells of the eye. Fluorescein is a diagnostic contrast agent particularly used in various ophthalmic procedures, such as checking for any corneal or vessel abnormalities. The application of fluorescein also extends to bioimaging whole anatomic structures and even further to cellular components in immunohistological staining.

Tropicamide is an eye drop medication primarily used to dilate the pupil (mydriasis) and temporarily paralyze the eye's muscles (cycloplegia) during eye exams and procedures. It is an anticholinergic agent, meaning it blocks the action of acetylcholine, a neurotransmitter that controls eye muscle movement. This allows for better visualization of the eye's internal structures.
