It can be done that the effects of botulinum toxin continue being regional from the concentrate on muscle at reduced doses, but systemic anticholinergic effects from the drug is often noticed at better doses or when in nearer proximity to vascular constructions in the injection websites [thirteen, fifteen, sixteen]. Treatment of glabellar rhytides with botulinum toxin may lead to lagophthalmos and immediate paralysis of your lacrimal gland, leading to dry eyes and superficial punctate keratitis [17]. Periorbital botulinum toxin injection can result in mydriasis with the pupil, causing acute angle closure assault. Cases happen to be noted through which the botulinum toxin was improperly injected into the vitreous cavity of a affected person receiving treatment to the correct medial rectus, causing improved intraocular force, decreased Visible acuity and retinal detachment [eighteen].
