Can getting Botox or Dysport in nose (to address bunny lines) decrease tears in lacrimal sac or tear ducts?

Hello, 

I'd be happy to answer this question for you. Having Botox or Dysport in your bunny lines won't effect tear production or dry eyes, only the muscle that's being treated. I hope this answers your question

Dr. Gregg Kennedy

Normally injection in the glabellar area should not affect tearing or the function of the eyelids. Injection in the crows feet area can affect the laxity of the eyelids and consequently aggravate dry eye symptoms .  If the injection is done too low and too much in the glabellar area , by dissipation the function of the eye lids can be affected. All these symptoms should resolve within 3 to 4 months if they are due to the injection.

The injector would have to have injected practically into the corner of the eyelid to involve and glands. The bunny line treatment is far enough away from the eye to cause any problems. As far as the high dose its not uncommon for someone having the glabeallar are, forehead and crows to receive 150 units. I don't know haw many you had but generally thats a common dosage.
