I had Restylane injections under my eyes and ended up having a Retinal Arterial Occlusion (stroke) in my right eye that resulted in a blind spot. I was tested for everything under the sun, and there was no other explanation. I'm sure it was NOT reported so be careful when you hear that there are only "one or two" reported cases! I would only let a doctor trained in the anatomy of the eye do an injection again. And, most people don't know that none of the fillers are FDA approved for injection under or around the eye. That is considered "off label" use. My doctor never warned me of that or the potential for a stroke in my eye. So ask questions about this and know that, although relatively rare, this does happen more often than the literature reflects.
