There are several risk factors when using Botox around the eyes.Perhaps the most common reason patients develop asymmetry is uneven brow ptosis from having the forehead treated. To treat the vertical forehead lines, a muscle called the frontalis is injected. This muscle is used to raise the eyebrows. Botox treatment to the forehead will cause some droopiness of the eyebrows. In the ideal situation, this is kept to a minimum. Patients with low, heavyset brows are generally not good candidates for having this treatment. To determine if the Botox treatment in the forehead was done asymmetrically, lift your brow and see if you can form wrinkles on one side. When that is the case, a touchup Botox treatment is sometimes indicated. Another problem that can happen with Botox treatments is the weakening of the muscle that lifts your eyelid. When this happens, the eyelid sits lower on one side, encroaching on the pupil. I don't see this based on your picture.This can happen if the muscle that raises your eyelid is accidentally contaminated with some of the Botox. It most commonly happens when doctors (or nurses) try to give a Botox brow lift. When it happens, there are eyedrops that can temporarily reverse this complication. Eyelid drooping from Botox typically wears off sooner than the rest of the Botox treatment. The third complication is Botox affecting the muscles that moves the eye itself. This is a very rare complication. When it happens, patients will experience double vision. Most undesirable side effects from Botox treatments go away with time and often sooner than the three months expected from Botox treatments. I suggest following up with your provider to, first of all, have a proper assessment and, secondly, see if there are some options to help you until the Botox wears off.Best of luck,Mats Hagstrom, M.D.
