Does Botox in Eyebrow Cause Light Sensitivity?

Pain

Take a look in the mirror and see if your right pupil is dilated relative to the left pupil.  If this is the case, then the BOTOX treatment has seemed into the right orbit affecting the levator palpebra superioris muscle- the muscle that lifts the eyelid and also the ciliary ganglion.  If the effect is profound and the onset rapid, it is likely a significant dose of BOTOX entered the orbit.  The heavy eyelid could last several months.  If this is the case, the iopidine drops will not be helpful for quite a while.  Once the do help open your eyelid, the remaining ptosis will resolve about 4 to 6 weeks later.  I would recommend that you get seen by an ophthalmologist.  Don't have service with the doctor who did this treatment again.

Complications from Botox and Dysport are relatively rare as they are very safe and effective medications. 

However,  tou have likely described one of the possible problems which can arise after Botox injections around the eye.  If some of the medication find its way down into the upper eyelid, it can cause droopiness of the upper lid, and dilation of the pupil.  This usually can be corrected temporarily with some medicated eye drops, and will eventually resolve when the Botox wears off.  

There are some other possiblities for the cause of the problem, but I would recommend you go see the doctor who administered the injection.  They should be able to diagnose and treat the problem.
