I recently published a paper on persistent ptosis after periocular botulinum toxin. What we found it that the botulinum toxin needs to wear off enough for the iopodine can work. Response to iopodine predicted that the ptosis would wear off in 4 to 6 weeks. If you are not responding to Iopodine, this predicted that the ptosis could persist for longer than this. In most cases, these longer periods were 3 to 4 months but one patient had persistent ptosis for 12 months. Have you actually seen a physician regarding a prescription for Apraclonidine the generic for Iopodine? Naphazoline, the active ingredient in Visine has a similar effect. Consider getting an appropriate assessment of your ptosis.
The eyelid drooping will start to improve on its own in 4-6 weeks. Alphagan P or generic brimonidine can be prescribed to help lift the eyelids 1-2 mm. This may be enough to make you feel better. These drops are by prescription by your provider.
