Lazy Eye (Strabismus) Treatment
Strabismus, commonly known as lazy eye or squint, refers to a misalignment of eyes. Squints can be broadly classified into three groups:
Esotropias: It is a clinical term for a convergent squint where the eye turns in towards the nose.
Exotropias: It is a divergent squint where the eye turns outwards.
Hypertropias and Hypotropias: They are vertical squints where the eye becomes lower (hypotropia) or higher (hypertropia) than the fellow eye.
Botox is a safe and dependable treatment for misaligned or lazy eye. Oculoplastic surgeon Dr. Jennifer Hui provides eye care procedures to patients in Palm Springs, Palm Desert, La Quinta, Coachella Valley, Riverside, Redlands, Yucaipa, Loma Linda, and surrounding locations.
How does Botox Work?
Botox or botulinum toxin type A has been used since the 1970s as a non-surgical treatment for squints. It is a highly effective way to correct the position of the eyes. The neurotoxin will loosen the overactive muscle causing the squint by temporarily blocking the signals between the muscle and the nerve.
When the electrical signals pass from the nerve to a muscle, a chemical is released from the nerve end into the space between the muscle and the nerve. The chemical then bonds with the receptors on the muscle cells, which in turn delivers a signal to the muscle cells, causing their contraction.
Botulinum toxin or Botox sticks to these muscle receptors, which prevents the chemical to bond with them. As a consequence, the muscle will not receive the signal to contract. After the Botox injections, the muscles will start loosening in the treated site within one to two days. You can notice the maximum weakening effect in about two weeks following the treatment.
In about three to four months, the muscle will usually regain its active function, but with repeat treatments, you may be able to extend the benefits of Botox.
Botox Misaligned Eye Correction Procedure
In teens and adults, the eye surgeon may perform Botox treatment in their office using anesthetic drops for numbing the area. Once the numbing effect is achieved, the surgeon will inject Botox directly into the eye muscle with the help of a fine need connected to an EMG (electromyogram).
When the needle is in position, you will be asked to move the eye to create muscle contraction. The EMG will catch the contracting muscle’s signal, so your treatment provider will know that the needle has been correctly placed. They will inject a tiny quantity of Botox (about 0.1 ml in most cases) into the eye muscle and remove the needle after 30 seconds. The pause will help to minimize the risk of Botox spreading to surrounding healthy tissue.
Treatment for Children
The ophthalmologist may perform Botox treatment for children using a ketamine anesthetic or a general anesthetic. With a ketamine anesthetic, the Botox injection can be performed the same way as adult treatments. In case of a general anesthetic, the surgeon will create a tiny opening in the conjunctiva to see where Botox should be injected. No sutures will be necessary to close this tiny opening.
