Occlusion therapy of unilateral amblyopia with botulinum toxin induced ptosis

Semin Ophthalmol. 2007 Jan-Mar;22(1):55-7. doi: 10.1080/08820530601182709.

Abstract

In order to evaluate the role of botulinum toxin induced ptosis as an occlusion method to treat unilateral deep strabismic amblyopia in two uncooperative children, we injected 0.2 ml of diluted botulinum toxin in the levator palpaebrae; low sedation was necessary in one of the two children. In both cases a marked ptosis was achieved, which lasted about four weeks and then gradually resolved completely. The visual acuity of the ablyopic eye increased in both children, making patching easy thereafter. One child developed amblyopia in the injected eye, which was handled successfully using part-time occlusion. No other side effects were noted. Whether this new method could be a simple, safe and effective alternative method of occlusion for the treatment of deep amblyopia in uncooperative children needs to be proven with a larger series of children.
