Indocyanine green angiography (ICG) is a diagnostic procedure that uses a special dye and camera system to visualize blood flow in the vessels of the retina and choroid, which are parts of the eye. This technique is particularly useful for evaluating conditions related to the deeper layers of the eye, such as choroidal neovascularization, which can occur in diseases like age-related macular degeneration (AMD).
The fundus cameras we offer use a variety of technologies to help you get to the root of your eye problems. Microclear Apollo ultra widefield CRO PLUS with ICGA Pushing the boundaries of Indocianine Angiography. Fast, precise, and flexible management of your ICGA sessions with multiple options.
Dye: Indocyanine green (ICG) is a fluorescent dye that is injected into a vein, usually in the arm. The dye travels through the bloodstream and into the blood vessels of the eye.
Imaging: A specialized camera with infrared capabilities captures images of the dye as it flows through the ocular vasculature. Unlike fluorescein angiography, which primarily highlights the retinal vessels, ICG is more specific to the choroidal circulation.
Diagnosis: Helps diagnose various retinal and choroidal diseases.
Monitoring: Useful for monitoring the progression or treatment response in certain conditions.
Research: Contributes to the understanding of ocular diseases.
Preparation: The patient's eyes may be anesthetized with drops.
Injection: The dye is injected, and the patient’s eyes are observed using the specialized camera.
Imaging: Sequential images are taken over several minutes to capture the flow and leakage of the dye.
Provides detailed information about the choroidal vasculature.
Can differentiate between retinal and choroidal pathology.
Potential allergic reactions to the dye, although they are rare.
Temporary skin discoloration or staining.
Requires specialized equipment and expertise.
Images are analyzed by ophthalmologists to identify abnormalities such as new vessel growth, leaks, or other signs of disease.
