Angiografía Fluoresceínica

La angiografía es un examen diagnóstico, con el que obtenemos fotografías de la retina. Se realiza para diagnosticar enfermedades o problemas en la retina. En este procedimiento es necesario inyecta r un medio de contraste para obtener las imágenes fotográficas. El examen se puede realizar con dos sustancias (medios de contraste - colorantes) diferentes, Fluoresceína Sódica para ver el sistema vascular de la retina o Indocianina Verde para analizar los vasos de la coroides (capa que recubre la retina).

El examen requiere previa dilatación pupilar y el procedimiento tiene una duración de 20 minutos con fluoresceína y una hora y media con Indocianina.

Fluorescein angiography

Fluorescein angiography, or fluorescent angiography, is a technique for examining circulation of the retina to determine and diagnose the extent of retinal disease. It involves a dye tracing method with a series of digital photographs of the fluorescence emitted after illumination of the retina with blue light.

This exam can be done with different dyes depending on the vasculature to be studied. Fluorescein is used to study the retinal vasculature, while indocyanine green is used to study the choroidal (connective tissue) vasculature.

The procedure requires pupil dilation. The duration of the procedure is around 20 minutes for fluorescein angiography, and 1 hour for indocyanine angiography.

The exam is commonly performed for various retinal, choroidal, or optic nerve diseases, revealing important information for diagnosis and appropriate treatment.
