What is strabismus?
Strabismus is loss of parallelism between both eyes, there being a fixing eye (straight) and a deviated eye. You can always divert the same eye or alternatively divert one or the other eye.
What does the strabismus consultation consist of?
1.
A clinic history of the patient where their personal and family health history will be recorded.
2.
To determine if the patient has strabismus, a ophthalmological examination complete: visual acuity and possible refractive error, and examination of the anterior and posterior segment of the eye.
3.
will be made specific tests of ocular motility and binocular vision for the diagnosis and assessment of strabismus.
4.
In all probability it will be necessary instill drops of a medicine cycloplegic that will dilate the pupil and cause blurred vision for a few hours to a day.
What treatment do we offer?
First, any refractive error will be optically corrected. Depending on the age of the patient and whether there is amblyopia (lazy eye), penalizing treatment of the dominant eye may be necessary (occlusion, penalizing with atropine, filters).
The fundamental treatment of strabismus is surgery, both in children and adults.
What does strabismus surgery consist of?
Strabismus surgery acts on the extraocular muscles responsible for eye movement. Depending on the type and intensity of the deviation, one or both eyes will be affected. in operation The most active muscles are weakened and/or the weakest are strengthened.
What are the objectives of strabismus surgery?
- Strabismus in childhood is frequently associated with a lazy eye and surgery helps to recover visual function. The main objective is to achieve reduce or eliminate the deviation and can be done at any age. It is usually a Ambulatory surgery, and it can be with general anesthesia or local anesthesia in adults.
- In children and adults, binocular vision – three-dimensional vision, depth vision – can be restored if they previously had it. In strabismus in early childhood and in adults with long-standing strabismus Although they do not achieve three-dimensional vision, they can improve their field of binocular vision and sensation of unique vision. Adults frequently experience an improvement in their self-esteem and ability to communicate with others.
- En late onset strabismus In both children and adults, there may be a symptom of double vision that will disappear if perfect alignment is achieved between both eyes, which is not always possible (for example, some types of paralysis in which movement is not fully recovered).
- Some adult patients with double vision due to small deviation strabismus may benefit from treatment with prisms (lenses that shift the image and eliminate double vision).
- In some cases surgery is indicated to correct torticollis (abnormal head position) secondary to some abnormality in eye movement.
- It is also indicated in nystagmus, rhythmic and involuntary movement of the eyes, to try to block said movement.
- The surgery does not modify visual acuity or the prescription of glasses. In some strabismus associated with hyperopia there is a part of the deviation that is corrected by adjusting its prescription. In these cases, the objective of surgery is only to correct the deviation that is not corrected with glasses on.
What is botulinum toxin and what is it used for in strabismus?
It is a neurotoxin that acts at the muscle level by inhibiting the release of the neurotransmitter (acetylcholine) in the nerve endings of the muscle into which it is injected. This will cause temporary paralysis of said muscle.
It is an alternative or a complement to the surgical treatment of strabismus. The use of botulinum toxin in the treatment of strabismus aims to restore the parallelism of the eyeballs and the disappearance of torticollis if it exists. In children, it will help the eye develop correct visual function. In the case of paralytic strabismus in adults, double vision is intended to be eliminated.
What are the possible risks and complications of surgical treatment of strabismus?
La success rate, that is, stable eye alignment, oscillates between 50 and 80% with a single surgery
It is not uncommon for multiple interventions to be needed to normalize the position of the eye. Successive interventions increase the difficulty of surgery and the possibility of complications.
Your ophthalmologist specializing in strabismus will inform you in detail about your treatment options as well as the possible risks and complications individually according to your case.
