A fully dilated pupil, a flash digital camera, and blinding white light.
Searing pain, as that light hits your unprotected retina.
Over and over and over again.
Then being told to sit back and rest your eyes.
Opening your eyes, and seeing the world through a purple tinge.
The poke of the needle on the back of your hand.
Then more flashes, blue light this time, as the camera records the dye entering the vessels at the back of your eyes.
Forcing your eyes to open wide into the light, knowing the intense pain to come.
Flash after flash, you begin to anticipate the pain and blink too soon.
Thankfully, it is eventually over.
For a moment, you can see nothing but a white aura.
Then it clears, and you see the world blurred and through a yellow haze, courtesy of the dye.
Don't forget the brown and purple bruise on the back of your hand from the needle.
The tenderness of the bruise, as your hand brushes against objects.
That's a fluorescein angiogram.
For anyone who didn't know.
