Abstract Background Oxymetazoline hydrochloride ophthalmic solution (0.1%) is a medication used to treat blepharoptosis. Patients who suffer from blepharoptosis have low-lying eyelids that can hinder their vision. Oxymetazoline hydrochloride ophthalmic solution (0.1%) is prescribed to patients to improve their vision by lifting the upper eyelids. Blepharospasm consists of involuntary, bilateral orbicularis oculi muscle movements that result in twitching and eyelid closure. Botulinum toxin is a treatment used to treat blepharospasm by preventing muscle contraction; but it is not always effective. Case presentation The effects of treatment with both oxymetazoline hydrochloride ophthalmic solution (0.1%) and botulinum toxin are assessed in three patients: (1) Patient A, a 58-year-old Filipina woman; (2) patient B, a 62-year-old Korean woman; and (3) patient C, A 57-year-old Vietnamese woman. All patients had been diagnosed with blepharoptosis as well as blepharospasm. Each patient was given an opportunity to complete an optional survey to assess not only the efficacy of oxymetazoline hydrochloride ophthalmic solution (0.1%) together with botulinum toxin but also their perceived stress during the past month. Conclusions Administering botulinum toxin for the treatment of blepharospasm in patients A and B yielded the expected results; adding oxymetazoline hydrochloride ophthalmic solution (0.1%), a medical treatment for ptosis, to the treatment regimen yielded an unexpected reduction of blepharospasm. We propose that botulinum toxin and oxymetazoline hydrochloride ophthalmic solution (0.1%) can have a synergistic effect on reducing blepharospasm when used concomitantly. We present three cases in which combined use of botulinum toxin with oxymetazoline hydrochloride ophthalmic solution (0.1%) reduced blepharospasm, and propose possible reasons for such effects. We also discuss previous literature in agreement with the results of our cases.
