dysport and olss of eye sight

I am a 48 year old male in very good health, I received injections of dysport around my eye upper and lower.  The first injection resultrd in a large black eye, when I returned to the Doctor she said it was nothing and gave mer additional injections around my eye.   Within 24 hours I started see a black cloud in my left eye and within 4 dayslost 50% vison in that eye.  I have been to every specialist being tested from everything from glaucoma to MS, everything within the rest of my body is 100% heathly except the back of my eye and the area where the injections were admitted.  The doctors cannot understand this sudden eye lose.  I am hoping that when the dysport where off my sight may return but have not been able to get the docter that gave me the injections that this could be a pssibility.

This sounds like a mahor problem.  I don't believe Dysport is approved for that in the US.  My understanding is that it is like Botox. I wonder if somehow the drug went directly into a vessel perhaps.  Sorry but I really can't give you any special advice other than to see the best local ophthalmologist and find out exactly what happened.  It may or may not be related to the injections.
