Does Dysport cause double and blurry vision?

Thank you for your question. While it is not common for Dysport to cause the types of side effects you are describing, there is the chance that an injection performed incorrectly could cause vision issues. However, that is something best addressed by an ophthalmologist after an in-person consultation. For future reference, it is always best to see a very experienced, qualified injector when getting injectable treatments who is experienced and familiar with the facial structure and will provide you with safer, more beautiful results. Best of luck!

This is very concerning and I'm so sorry you are having this issue. I would see an ophthalmologist and your physician right away regarding your concerns. As for dysport, there is always a possible side affect of blindness, brow or eyelid dripping, lazy eye, double vision, orbital injury if applied around the eye or the orbital forehead or nasal tissue. I wish you the best in your findings and recovery.

The symptoms you are experiencing are concerning. I encourage you to return to your injector for an evaluation. Further assessment is needed to determine if the Dypsort treatment is related to your symptoms.

Assuming proper injection, immediate side effects may include lightly swollen pinkish bumps and irritation at injection side that subside after a couple hours. In general, if it continues to feel uncomfortable, consult your doctor to get a complete assessment.

It is possible that the Dysport has affected the muscles that move the eye. This will result in double vision because the eyes won't move in tandem. Injecting these muscles was actually the first approved use of Botox for patients with strabismus, or "lazy eye". Unfortunately, this can't be corrected and the Dysport will have to wear out over the next 3-4 months. I understand that this is a very difficult problem you are experiencing and you should seek an Ophthalmology consultation to make sure that this is actually the problem. The treatment might entail an eye patch so your brain only sees one image and therefore eliminate the double vision. This will affect depth perception though. The problem is cause by injecting too close to the eye in the crowsfeet area or with too large a dose/volume. 

i'm so sorry you have been having this issue! 
hard to say what is happening without an exam. if the dysport was injected inside the orbital rim at your crows feet there is the possibility that it was injected close enough to the orbital septum to effect the lateral rectus muscle and cause double vision, especially if the double vision is side by side. the doesn't address the swollen bridge of your  nose though - 
there are definitely other reasons for these symptoms as well. you should be evaluated by an ophthalmologist quickly for the double vision issues
good luck

Hello. Thank you for your question. I have never heard of this happening from Dysport. If you were to have a reaction like that, I would think it would be right after your injection. If you are still having this issue I would consult a physician.
