Strabismus Surgery
Relevant information about Strabismus Surgery.Strabismus is the scientific term of the eye movement’s deviations. The Strabismus Surgery is a treatment over the eye’s muscle/s, used to improve vision performance or patient’s normal appearance. This eye muscle/s surgery has become a highly skilled procedure.
Each of the eyes has six outside (extraocular) muscles controlling eye movements. The common consequence of these anomalies is an inadequate binocular vision performance that causes eye focus malfunction, double vision and a restricted visual camp. Beside, having an eye in a different direction that the other one make the patient feels bad about his/her personal appearance, affecting his/her relationships with other people. Synchronize the eyes movements is the objective of the ophthalmologist’s intervention. The six eye’s muscles must work coordinately. Strabismus may be noted by the patient themselves (especially if it is causing double vision) or by family and friends. Strabismus is often detected by an Optometrist during a routine eye examination or by a patient’s General Practitioner.
First of all, is necessary to remind that Strabismus problems could be treated with Eye Therapy that not involves surgery. The decision of what technique follow has to be made with the ophthalmologist’s advice. Is also important the patient’s willing to the surgery procedure, risk knowledge and money cost. The Strabismus Surgery does not require incision on the skin. The eye is not pulled out of the socket. The incision is almost always made behind the eyelid so the incision itself is usually not visible. In a recession procedure, ophthalmologist detaches the affected outside 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. In contrast, if the muscle is too weak, ophthalmologist may use a recession procedure to reduce strength of the opposing muscle (antagonist) to achieve more balanced function of the eye muscles. In certain cases, a resection procedure may be used to strengthen an eye muscle to correct misalignment. If the patient has inwardly turned eyes (esotropia), the ophthalmologist may strengthen the lateral rectus muscles — located on the side of each eye, toward the ear — by reattaching the muscle in a different location (resection). The lateral rectus muscles are strengthened and they can turn the eyes farther outward. This results in better eye alignment. In cases of adjustable suture surgery type, it is performed in the operating room. Afterward the eye is patched. Some surgeons prefer an antibiotic or combination antibiotic/steroid drop or ointment after surgery. Normally a day after procedure, the patch is removed in the office, once the anesthesia and sedation have faded. Based on how the eyes are aligned, the ophthalmologist may decide to use the suture that is in place to tighten or loosen the treated muscle. This adjustment might cause slight discomfort, primarily with muscle tightening. Once the desired alignment is achieved, the surgeon ties the adjustable suture permanently in place, and the procedure is complete. If it’s necessary, a new or many surgeries will have to be made. This depends of the problem treated importance, possible complications or ophthalmologist’s requirements. Also the surgery might be complemented with post procedure eye’s exercises.
The eyes will be red and somewhat sore after Strabismus Surgery. Eye redness should fade within two to three weeks. The sensations that there is something in the eye will disappear in a shot time, and diary activities can be soon reassumed. The amount of pain following surgery is variable, depending the age of the patients and the type of method followed. During the first few days after surgery, eye alignment is an excellent sign of the final outcome. However, most of the permanent results may not be known until four to six weeks after Strabismus Surgery. Children younger than 9 years old will likely need a second or third surgery, to obtain better results, as well as eyeglasses or special lenses. Rehabilitation exercises might be used as a complement of the surgery procedure.
Anesthesia is one of the risk factor on the patient’s life. Anesthesiologist must make pre-surgical exam to the patient in order to check his/her vital conditions. Allergies and others factors are also of main important consideration. The most severe complications may include retinal detachment or Endophthalmitis, which is inflammation of the eyeball. Infections and surgery incision blooding may be develop. Patients in poor health may require hospitalization for a closer health care. Of course, surgery procedure could fail, being the eye or the muscle/s damages. A new surgery might be needed, sometimes immediately in order to avoid permanent disabilities.
It is important to differentiate between the patients looking for a visual improvement, from the patients that search an esthetical optimization. Eye visual function will be priority in the first case; esthetical correction in the second one. The success of the surgery is dependent on the ability of the eyes to work together as a team, or the ability of the patient to fuse or combine the image from each eye successfully into a single image. One eye muscle operation has about an 80% success rate. As have been told, another/s surgery/ies could be needed. Resuming, the aims of Strabismus Surgery are:
Strabismus Surgery is an eye’s muscle/s procedure. These muscles are controlled by the brain, through the optical nerve. However, the surgery does not involve nerve terminations or an intervention in patient body’s nervous system. Although ophthalmologist considerate that surgery as a success, resulting eye function might not be the ones looked for. It depends of the patient previous condition, the specific problem treated and the eye physiology. The Strabismus Surgery is not considerate an esthetical procedure, but a reconstructed one. Socials works could not support it.
