What is rectus resection?
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 lateral rectus muscle?
The lateral rectus is a flat-shaped muscle, and it is wider in its anterior part. The lateral rectus muscle is an abductor and moves the eye laterally, and side to side along with the medial rectus, which is an adductor.
What is resection of a muscle?
To strengthen a muscle, a section of the muscle or tendon may be removed to make it shorter. This step in the surgery is called a resection. To weaken a muscle, it is reattached to a point farther toward the back of the eye. This step is called a recession.
How do you isolate lateral rectus?
To address the slippage of the lateral rectus muscle bridle effect, a Y-splitting procedure of the lateral rectus muscle can be performed by splitting the muscle from its insertion as far posteriorly as possible, spreading the muscle halves 10 mm above and below the original insertion at the desired recession point.
What is resection eye surgery?
What is a resection/plication? A resection strengthens muscle function by shortening the muscle and then reattaching it to the eyeball at its original position, similar to cutting an elastic band, but still stretching it to the original length. A suture is placed through the muscle at the new intended length.
What happens when the lateral rectus is damaged?
Damage at any point along its path can cause the nerve to work poorly or not at all. Because the lateral rectus muscle can no longer contract properly, your eye turns inward toward your nose. Sometimes, sixth nerve palsy happens without any other symptoms. This is called isolated sixth nerve palsy.
Why does my lateral rectus hurt?
If lateral movement of the eye is limited or if that movement causes pain, it may be indicative of injury or dysfunction of lateral rectus. Lateral Rectus Muscle Palsy (LR Palsy) is a condition where dysfunction in lateral rectus is experienced secondary to damage or disease in cranial nerve six (abducens nerve).
How long does eye muscle surgery last?
Eye muscle surgery is an outpatient procedure which typically lasts between 30 minutes and two hours. Once the surgeon finishes, patients need an hour or so to wake up from the anesthesia. During this time, your doctor will monitor you to make sure there are no unintended aftereffects.
How do you strengthen the lateral rectus muscle?
Lateral rectus exercises The cardinal point exercise involves looking to the extreme in each direction – up, down, right, and then left. Hold your eyes in position for ten seconds at each cardinal point. Repeat the exercise a total of five times. The eye rolling exercise is exactly what it sounds like.
What is the recovery time for eye muscle surgery?
Your child may return to normal daily activities, but should not participate in gym class, swimming, or other sports or physical activities for at least 2 weeks after the surgery. Your doctor will need to see your child again for a check-up in approximately 4 to 6 weeks after the surgery.
Does eye muscle surgery improve vision?
In fact, vision loss could become a permanent disability if treatment isn’t received promptly. Eye muscle repair surgery helps realign the eyes so that both point in the same direction. This procedure is most often performed on children with strabismus, but it may also be done to help adults with eye muscle problems.
How do I strengthen my lateral rectus?
What cranial nerve controls the lateral rectus eye muscle?
cranial nerve VI
The abducens nerve (cranial nerve VI) exits the brainstem from the pons-medullary junction and innervates the lateral rectus muscle.
Can you watch TV after eye muscle surgery?
Avoid strenuous activity, such as lifting or contact sports for 14 days following surgery. Sleep with your head elevated on 2 to 3 pillows for 5 to 7 days to reduce pain and swelling. Avoid swimming and activities in which sand or dirt may enter the eye for 14 days. There are no restrictions on reading or watching TV.
Is eye muscle surgery successful?
The success rate of eye muscle surgery is 60-80 percent. This means that on average, 7 out of 10 persons who undergo eye muscle surgery will achieve a good result with only one procedure. The remaining three persons may, at some point, be benefited by additional surgery for good eye position.
