In ophthalmology, there have been few reports of botulinum toxin type-A (BTX-A) injection into the lacrimal gland to treat epiphora. In ENT, adductor and abductor (ABSD) spasmodic dysphonia are often treated with BTX-A injections into the respective overacting vocal cord muscles. We describe a 53-year old male with Parkinson's disease who did not respond to BTX-A injections to either the lacrimal gland, for epiphora secondary to Parkinsonian-related blink lagophthalmos, or posterior cricoarytenoid (PCA) muscles for ABSD. Subsequent BTX type-B (BTX-B) injections into the lacrimal gland remarkably improved his epiphora. BTX-B injections into the PCA muscle also greatly improved his dysphonia. We describe the first reported case of (1) BTX-B injection into the lacrimal gland for epiphora, (2) use of Botox in treating epiphora due to blink lagophthalmos/reduced blink frequency secondary to Parkinson's disease, (3) BTX-B use in treating ABSD, and (4) association between ABSD and Parkinson's disease.
