Abstract
Formulations and methods of treatment are disclosed for prevention and/or treatment of visual loss from age-related macular degeneration. The disclosed formulations include botulinum neurotoxin (e.g., botulinum neurotoxin or a fragment thereof, either in pure form or with one or more peptide fragments and/or neurotoxin associated proteins). In some embodiments, the disclosed formulations also include one or more anti-VEGF agents. The disclosed formulations may be applied to an intraocular or extraocular region of a patient. If applied to an extra ocular region of a patient, the botulinum-based pharmaceutical formulation may be transported to the intra-ocular region of the patient via axoplasmic transport, thereby allowing the active ingredient(s) to penetrate into the choroid, neuro-retina, and/or retinal pigment epithelium without direct injection into the eye, allowing for improved therapeutic safety by eliminating risk of retinal detachment, retinal break, retinal hemorrhage, and blindness associated with direct injection into the eye.
