Botulinum toxin injection for the treatment of strabismus?
I have strabismus and although I underwent a successful strabismus surgery that corrected my eye alignment, 20 years later, my eyes have started to deviate again.
After a second surgery that was unsuccessful, I am currently receiving botulinum toxin injections for strabismus treatment.
I would like to know if Dr.
Liu could assist me with my treatment.
I would greatly appreciate your response.

Hello, Madam: You previously underwent strabismus surgery to correct your eye misalignment, but it has since deviated again, and you have experienced an unsatisfactory secondary surgery.
Generally speaking, the difficulty of a repeat surgery is inherently higher.
Additionally, do you have any issues with amblyopia? In cases of amblyopic eyes, even after a successful strabismus surgery that restores proper eye alignment, there is a high likelihood that the amblyopic eye may deviate again over time, often increasing in severity.
Therefore, whether to recommend another surgery (including botulinum toxin injections) should be based on a comprehensive evaluation before determining the treatment direction.
Wishing you good health.
Dr.
Liu Jing-Hsi, Ophthalmology, Taipei City Hospital, Zhongxing Branch.

Botox injections have emerged as a promising treatment option for strabismus, especially in cases where surgical interventions have failed or are not viable. Strabismus, commonly known as crossed eyes, occurs when the eyes do not properly align with each other. While surgical correction can be effective, some patients may experience a recurrence of misalignment over time, as you've described in your situation.
The use of Botox (botulinum toxin) in treating strabismus involves injecting the toxin into specific eye muscles. This causes temporary paralysis of the injected muscle, allowing the opposing muscle to take over and help realign the eye. The effects of Botox are not permanent, typically lasting for about three to six months, which means that repeat injections may be necessary to maintain the desired alignment.
One of the significant advantages of Botox injections is that they are less invasive than surgery. For patients who have had unsuccessful surgical outcomes, Botox can provide a non-surgical alternative that may improve eye alignment and reduce symptoms associated with strabismus, such as double vision or eye strain. Additionally, Botox can be particularly beneficial for adults who have developed strabismus later in life, as it allows for a more conservative approach to management.
However, it is essential to have a thorough evaluation by an ophthalmologist or a specialist in strabismus before proceeding with Botox treatment. The physician will assess the specific type of strabismus, the muscles involved, and the overall health of your eyes. They will also discuss the potential risks and benefits of the treatment, including the possibility of side effects such as ptosis (drooping eyelid) or temporary vision changes.
In your case, since you have already undergone two surgeries with limited success, Botox may offer a new avenue for managing your strabismus. It is crucial to have realistic expectations regarding the outcomes, as while many patients experience improvement, the degree of success can vary. Some individuals may achieve significant alignment, while others may notice only modest changes.
Furthermore, it is worth noting that Botox is often used in conjunction with other treatments, such as vision therapy, to enhance the overall effectiveness of strabismus management. Vision therapy can help improve coordination and strengthen the eye muscles, potentially leading to better long-term outcomes.
In summary, Botox injections can be a viable option for treating strabismus, especially after unsuccessful surgical attempts. It is essential to consult with a qualified specialist who can provide personalized recommendations based on your specific condition. With careful evaluation and management, Botox may offer you a renewed hope for improved eye alignment and quality of life.
