Purpose

To study lesions of the vitreous, choroid and retina with the use of Fluorescein angiography or infrared.

Advantages

Pictures of the iris, choroid and retina can be taken and stored when fluorescein angiogram (FFA) or ICG is being done.

This is done for diagnosis; to look for areas of high, low or no perfusion: location of the lesion and extent of the lesion. Post treatment FFA can be done and compared for validating success of treatment or for re-treatment.

Operating procedure

With the patient seated at the Fundus camera after proper consent and test doses being given, an infusion cannula is inserted and appropriate solution is kept ready. The camera and the operating system is switched on. Initial colour pictures showing the pathology of one or both eyes is taken.

The intravenous injection is given and pictures are taken at regular interval to assess the flow though the choroid, arteries, capillaries, veins. Depending on the suspected lesion early and late films are taken and also for regions of redistribution. Further management options like laser or surgery depends on findings acquired through the angiogram.
