Do Eyesight Problems with Dysport Wear Off?

Thank you for your question. This is very rare and is often due to poor injection placement. This is a rare side effect of Dysport. Dysport can cause vision changes when it spreads to the muscles that control the movement of the eye. Unfortunately, there is no way to reverse Dysport and will take time to resolve. I recommend following up with your ophthalmologist. Best of Luck!
 

Any problems with vision after Dysport or Botox SHOULD generally wear off when the treatments have worn off. You say your eyesight problems "came on quickly over the year" after you had your Dysport treatment. There are many different causes of vision problems that can cause a quick change in visual acuity. I recommend going right away to an eye MD (opthalmologist, not optometrist) and discussing this and making sure you get checked for other causes. Vision changes can be signs of serious internal health issues (high blood pressure, for example) as well as eye damage (glaucoma).

The only potential eye side effect with any cosmetic neurotoxin treatment is eyelid ptosis or temporary sagging of the upper eyelid. This would obviously cause an 'eyesight problem' because of upper visual field obstruction. But other than eyelid ptosis, Dysport is not known to directly cause any problem with the ability of the eye to see.

You did not mention what the "eye sight issues" are.

Dysport when injected properly in very small doses in the appropriate locations around the eye should affect that portion of the muscle surrounding the eye that causes these wrinkles and should not affect your vision.

Occasionally Dysport will diffuse beyond the intended area of treatment and affect other muscle groups as well. I noticed this problem when I first began to use Dysport after many years of injecting Botox without a problem.  Fortunately this is temporary and the unintended effect will correct itself over time.

I think it is important that have your eyes examined by an ophthalmologist to determine the cause of these "eye sight issues".
