Last June...2020, I had a retinal occlusion (eye stroke). This was 6 days following a laser procedure called trabecularplasty on that eye. Both the retina doc and glaucoma doc say there is not a cause and effect between the two. The stroke was caused by plaque or something that lodged there. (they checked both carotid arteries and found them clean)
Once the blood flow is interrupted in the retina, that part dies and vision is lost. In my case I still have about 15% peripheral vision out of that eye.....Right eye is 20/20 corrected.
A dye was injected making it easy to see the damaged part.
Here is another problem......the body wants to recover that vision so it grows new blood vessels in that dead part therefore increasing eye pressures. ........another laser procedure.....pan retinal surgery. The laser destroys the unwanted vessels and that, along with eye drops, keep pressures down.
If that doesn't work then a drain tube is installed in the eye. Scary.
The idea/goal is to save whatever vision is there. Did it happen to you?
Feel free to PM if you want to discuss more.
