What is Indocyanine Green Angiography?
Indocyanine Green Angiography (ICGA) is a medical imaging technique that uses a fluorescent dye to visualize blood vessels in the eye.
How is ICGA performed in mice?
ICGA in mice is performed by injecting Indocyanine Green into the tail vein and capturing images of the eye at different time points.
What are the benefits of using mouse models?
Mouse models allow researchers to study the mechanisms of diseases like age-related macular degeneration in a controlled environment.
What types of lesions can be detected?
ICGA can help identify various types of lesions in the choroid, which are important for understanding disease progression.
Can ICGA be standardized for research?
Yes, the study aims to establish ICGA as a standard procedure for characterizing choroidal lesions in research.
What is the significance of time course imaging?
Time course imaging provides insights into the dynamic changes in the choroidal vasculature over time, enhancing our understanding of the disease.
