Indocyanine Green Angiography (ICG)

Indocyanine Green Angiography (ICG) is most useful when your doctor or other qualified clinician needs imaging of Choroidal circulation for retinal, optic nerve, corneal or anterior-segment imaging. Please bring the referral or clinical question if one has been issued, because the exact protocol may depend on why this specific scan is being requested.

Please tell the imaging centre before your appointment if you have had a previous reaction to contrast material, have kidney disease, are on dialysis, or may be pregnant. Recent kidney-function results may be requested before contrast is given. Bring your glasses, contact-lens information and current eye medications. Pupil-dilating drops may be used for some eye imaging, so temporary light sensitivity or blurred near vision is possible. For Indocyanine Green Angiography (ICG) specifically, follow any appointment message from the imaging centre because the final protocol can change with your clinical history and the exact question being investigated.

Please provide the clinical indication or referral question for Indocyanine Green Angiography (ICG), relevant symptoms and duration, previous surgery or treatment involving Choroidal circulation, current medicines, allergies where relevant, and any previous imaging or reports that could help comparison.

At the appointment, staff will confirm your identity and the reason for Indocyanine Green Angiography (ICG), position you appropriately and acquire images of Choroidal circulation. The exact duration and positioning depend on the protocol and the number of views required.

Contrast use may require additional screening for allergy and kidney function. Any previous severe contrast reaction should be discussed before the day of the scan. The supervising team should complete the safety screen specifically for Indocyanine Green Angiography (ICG) before proceeding.

The images from Indocyanine Green Angiography (ICG) are reviewed by an appropriately qualified imaging specialist or clinician. The report should be interpreted together with your history, examination findings and other tests; an imaging result alone may not establish the final diagnosis. Urgent or unexpected findings may require faster clinical follow-up than the routine delivery time shown in this listing.

Please arrive early enough for registration and safety screening. The listed price for Indocyanine Green Angiography (ICG) is a starting market price and can change with contrast, sedation, additional sequences/views, radiologist subspecialty reporting, consumables or facility location. If your symptoms are severe or rapidly worsening, seek urgent clinical care rather than waiting for a routine imaging booking.
