APPLICATION
1. Auxiliary diagnosis of diseases: Sodium fluorescein can emit fluorescence under the illumination of fluorescent lamps after intravenous injection, helping doctors observe the condition of the fundus and diagnose retinal vascular diseases, choroidal and retinal lesions, etc. In addition, it can also be used to diagnose lesions in the nervous and cardiovascular systems, such as brain parenchymal abnormalities and myocardial ischemia.
2. Eye administration: Fluorescein sodium can be absorbed by conjunctival epithelial cells and produce a fluorescent reaction, indicating the location of the lesion. It is commonly used to evaluate ocular surface damage
3. Promoting corneal repair: Fluorescein sodium can promote the migration and proliferation of corneal epithelial cells, accelerate the repair process of corneal epithelial cells, enhance corneal transparency, reduce corneal opacity, and improve corneal transparency
4. Skin and mucosal staining: Sodium fluorescein can be hydrolyzed by esterases in living tissues to produce green fluorescence, used for staining and examination of skin and mucous membranes
5. Wound exudate examination: Fluorescein sodium can be used as an indicator to mark the possible presence of bacteria or other pathogens in the wound
6. In terms of environmental monitoring, as an indicator, it can effectively monitor water quality, air and soil pollution.
