Uso da toxina botulínica no tratamento do blefaroespasmo: Uma revisão bibliográfica

This study examines the use of botulinum toxin as an alternative treatment for blepharospasm, a condition characterized by involuntary muscle contractions around the eyes. The focus is on the efficacy and safety of this treatment in improving patients' quality of life. The article aims to review the scientific literature on the use of botulinum toxin for blepharospasm, understanding its effectiveness, mechanisms of action, and possible adverse effects. This is a bibliographic review based on the analysis of scientific studies published in recognized databases. Articles discussing botulinum toxin treatment, its clinical effects, and outcomes in patients diagnosed with blepharospasm were selected. Results and Discussion: The reviewed studies demonstrate that botulinum toxin is effective in treating blepharospasm, providing symptom relief for the majority of patients. Although some adverse effects such as eyelid ptosis and blurred vision may occur, adjustments in dosage and injection technique can mitigate these effects, leading to improved outcomes. Conclusion: The study concludes that botulinum toxin is a safe and effective option for the treatment of blepharospasm. However, individualized monitoring is necessary to tailor the intervention. Future studies should focus on improving application methods to further reduce side effects.
