What is Bimedial rectus recession?
Overview. Recession of the medial rectus is a measured retroplacement of the muscle from its original insertion. It is the easiest and most effective way of weakening the medial rectus and is the most commonly performed procedure in strabismus management.
What is strabismus recession?
In a recession procedure, your eye surgeon detaches the affected outside muscle (extraocular muscle) from the eye and reattaches it (resection) farther back on the eye to weaken the relative strength of the muscle if it is too strong.
What is residual esotropia?
Residual esotropia is a common problem following bilateral medial rectus (MR) recessions for esotropia. The patient was 30 years old men who underwent bilateral MR recession of both eyes in the childhood. Recession was repeated on the right eye few years after the first surgery, but residual esotropia progressed.
What is eye muscle recession?
What is a recession? A recession weakens function by altering the attachment site of the muscle on the eyeball. Once the muscle has been identified, a suture is placed through the muscle at the attachment site to the eye.
Is strabismus a disease?
Strabismus is a disorder in which both eyes do not line up in the same direction. Therefore, they do not look at the same object at the same time. The most common form of strabismus is known as “crossed eyes.”
How many surgeries does it take to correct strabismus?
In fact, most patients require just one corrective surgery over a lifetime. If it does come back, it’s usually possible for a skilled specialist to again reposition the muscles and restore the benefits of straight eyes for the patient.
Can esotropia return after surgery?
Residual and recurrent exotropia after successful extraocular muscle surgery is relatively common. Recurrence can occur shortly after bilateral lateral rectus recession and unilateral lateral rectus recession combined with medial rectus resection or years later.
Can damaged eye muscles be repaired?
This is known as a recession. Some people with strabismus require surgery in only one eye, while others may need to repair both eyes. One or more muscles in the eyes can be repaired during the same surgical procedure.
How is dissociated strabismus treated in infantile esotropia?
The incidence of dissociated strabismus is reported to occur in 60% to 80% of patients with infantile esotropia. 9 DVD is treated with superior rectus recession, inferior rectus resection, or inferior oblique anterior transposition. Dissociated horizontal deviation is treated with lateral rectus recession.
How does accommodative esotropia affect an infant?
Accommodative esotropia manifests as eye inturning secondary to the increased work of focusing through significant hypermetropia. Some infants may show some limitation of abduction upon initial examination of eye movements as a result of cross fixation.
When do you need surgery for infantile esotropia?
Most cases of infantile esotropia will require surgical intervention. Children with esotropia that present after 6-9 months of age and those who show limited abduction may require imaging. Occasionally infants with small angle esotropia <30 PD may be corrected with hypermetropic spectacle correction.
What causes inferior oblique overaction in infantile esotropia?
Inferior oblique overaction occurs in approximately 70% of patients with infantile esotropia. This is seen as over-elevation of the eye in supra-adduction. Latent nystagmus occurs in approximately 50% of patients with infantile esotropia.
