Results for tag: "Fluorescein Angiography"

Fluorescein angiography is a medical imaging technique utilized predominantly within the field of ophthalmology. The process involves injecting a fluorescent dye, typically fluorescein, into the bloodstream. As the dye circulates through the blood vessels of the retina and choroid—which are situated at the back of the eye—a specialized camera equipped with filters that let through only the specific wavelength of the fluorescing dye captures images. These photographs reveal the flow of blood through the retinal and choroidal vessels, allowing clinicians to diagnose conditions such as diabetic retinopathy, macular degeneration, and ocular vascular disorders. Fluorescein angiography is considered an essential part of radiographic imaging for ocular diagnoses, though it does fall into a niche category compared to more broadly used radiographic techniques such as X-ray, MRI, or CT scans. The output of this process is vital for treatment planning as it can detect abnormalities that may require interventions such as laser surgery or injections. Within the market, numerous companies specialize in manufacturing the fluorescein dye, as well as the angiography imaging equipment required for the procedure. Prominent players in this sector include Novartis AG (through its subsidiary Alcon), Carl Zeiss Meditec AG, Topcon Corporation, and Heidelberg Engineering GmbH. These companies provide a range of products from the fluorescein dye itself to advanced imaging systems, which contribute to the effective execution of fluorescein angiography. Show Less Read more
