Hi jharwood18
Usually an angiogram is done even before treatment starts if a swelling is found on the retina. This is part of the normal routine eye examination. A fluorescent dye is injected into a vein in the arm, which then shows if there is any blood or fluid leaking onto the retina and macula and to what extent. It is a straightforward, painless procedure unless you have a particular phobia of needles. Has your treatment already started?
Good luck.
Mine is usaually preceded by a plain photograph not a fluorescene angiogram and always with OCT which detects changes down to 1 micron.
The OCT is so detailed that a slit lamp examination is rarely carried out.

I have to disagree the slit lamp is used to check the anterior and posterior parts of the eye that OCT cannot. The OCT is for the inside only yet the slit lamp can look in a detailed way at the cornea, iris etc. My cysts on my eye ball were detected because of the slit lamp. I have a slit lamp test every time I attend clinic to check the health of the outside of my eyes as well as the inside.
Mine is a different condition, cystoid macular oedema.
Injections have been astonishing I went from blind to having vision, that was 7yrs ago. I had No76 three days ago.
Hi, sometimes in conditions such as myopic CNV, the leaks don’t show up very well on OCT scans, so it can also be another way of checking if fluid is still leaking. Good luck with your injections.
Thank you I found the second lot of injections very painfull
Was it the inj or after that was painful?
If the inj tell them you need more anaesthetic and a lighter touch.
If after inj this is usually sensitivity to the iodine or very dry eye ( if they've taken too long). Tell them you need lots of rinsing and ask about soothing drops (my gp prescribes them for me now) and they made a huge difference.
I did find too that inj in top of eye hurt more than in lower part ( maybe anaesthetic pools at bottom so you get more numb there?).
Anyway, tell your clinic how the last inj was so they can help make the next one better.
I've had scans and they can see the leaks, I'm wondering if I'm having this other test to see if the injections are working
A Fluorescein angiography is primarily used to tell how well the circulation is doing in your eyes. When the dye is put through your vein a whole series of photos are taken so that the dye can be tracked and seen how well it flows. I had an FA after many injections ( 40) and it showed I had ischemia and therefore it was no longer worth injecting as my vessels were blocked basically. To have an FA now means they can check the circulation and have a baseline to assess how your vessels are doing in the future and asses if there has been any changes. If you are offered one have it done mine cost £500 when I had it done privately.
Ok thanks I will im just worried about having one done
Don't worry, it's a simple procedure. Just an inj in your arm then a quick series of photos of the eye. There will be a nurse there the whole time who should explain what's happening. Your vision might be colour tinged after for the rest of the day (I think pink or yellow, can't remember ).
Best wishes going forward x

Thank yoy x
I really don’t think you need worry about it. I have had up to 5 a year almost every year since 1978.
The amusing thing is that the dye is yellow and and everything goes yellow, i do mean everything. 😃 It lasts for a few hours. I used to want the green version to frighten the office but that it is generally reserved for children.
Hello J Harwood,
A fluorescein angiogram is often given periodically as part of the monitoring process when someone is being treated for wet macular degeneration.
It would not usually be done every month. It would be done when you are first diagnosed and then usually after the first 3 injections.
After that, it would be at the discretion of your hospital ophthalmologist.
Best wishes
