Hi there,
sorry you have had some eye issues, but it sounds like you are having relevant tests, so I would feel confident so far aii lt is being done.
Until they call you back in, collate all the data and let you know what is going on, it is hard t know yet what stage you are at, if any, you don't mention any symptoms. What you have had done so far is retinal angiography and retinal photography, usually a couple of the first investigations, so do not distress yet, the most common thing is to set those baselines and keep a close watch on things.
During the angiogram A dye is injected into your arm. It flows through your blood to the blood vessels iin your eye. The dye makes the blood vessels in your eye easier to see as your doctor looks at your eyes through the camera.
You often have the photography as well, as some parts of the retina do not show up on angiogram. It is also basically non invasive ( has nothing that will really affect you badly ). Sometimes the dye can bring on a warm feeling or a small percentage are allergic, sounds like you went fine tho, and there are always plenty of people around to deal with issues.
Those tests were the first I had done. Retinal photographs are cool to look at , I have many on my walls in frames, sorta outer spaceish. Ask your specialist to explain one to you so you can run home and show your family
