This is a test which allows the blood vessels at the
back of the eye to be photographed as a fluorescent dye is injected into
the bloodstream via your hand or arm.
- To help the doctor confirm a diagnosis.
- To provide guidelines for treatment.
- To keep a permanent record of the vessels at the
back of the eye
- see an example
- Your pupils will be dilated with eye drops.
- An injection of yellow dye is given into a vein
in your arm.
- A series of photographs is taken as the dye enters
the vessels at the back of your eye.
- During the injection you may feel
warm or experience a hot flush. This only lasts seconds then disappears.
- Your skin will be pale yellow and your urine coloured
fluorescent green. This is entirely normal and may take two days to
wear off.
Yes. It is advisable to eat a light meal before the
test. If you have diabetes you must ensure you have had enough to eat.

| Should I take my
normal medication? |

Yes, all your regular medication should be continued.
You will be asked before the test what medication you are taking.
Yes, this is very important. Also inform us of any
allergies that you may have. If you think that you may be pregnant, please
inform the nursing/medical staff.
An appointment will be made for you to see the doctor
at the Out-patients Clinic. See http://www.vrmny.com/angiography.htm
and http://www.vrmny.com/BDR.htm
for examples of results.
No. The drops and bright light from the camera will
blur your vision for a short time. Please arrange for another adult to
collect you from the hospital and escort you home.
For this your pupils will need to be dilated with
eye drops, so you should not drive. If you do drive, staff may have to
refuse to put drops in your your eye and cancel the procedure.
Dilating your pupils stops you reading, and lights
become very bright, especially sunlight.
Some people do drive, especially if they wait an
hour or two after the drops are put in, so they wear off a little, but
this is not ideal.
Very occasionally the drops last 3 days, but usually
they last 1 hour with maximum effect, and are 80% better after 3 hours.
Reading or close work may still be slightly difficult after this. Using
sunglasses while your pupils are dilated is very helpful indeed. |
