Fluorescein
angiography (fluorescein - the type of dye that is used; angiogram
- a study of the blood vessels) is an extremely valuable test that
provides information about the circulatory system of the back of
the eye not attainable with a routine examination. FAs are useful
for evaluating many eye diseases that affect the retina.

The
test is performed by injecting a special dye called fluorescein
into a vein in the arm. In just seconds, the dye travels to the
blood vessels inside the eye. A camera equipped with special filters
that highlight the dye is used to photograph the path of the fluorescein
as it circulates though the eye. In many cases, these photos are
taken with a digital camera system, allowing the physician to interpret
the results immediately.
It
is a relatively safe OPD procedure. At Ahalia, FA is performed using
Carl Zeiss Visupac 450 digitized angiography system, which is top
of the line equipment giving excellent magnified images, which help
in treating diabetic retinopathies, Eale's disease, vascular occlusions
etc.
