Adjustable suture strabismus surgery.
Summary of "Adjustable suture strabismus surgery."
Surgical management of strabismus remains a challenge because surgical success rates, short-term and long-term, are not ideal. Adjustable suture strabismus surgery has been available for decades as a tool to potentially enhance the surgical outcomes. Intellectually, it seems logical that having a second chance to improve the outcome of a strabismus procedure should increase the overall success rate and reduce the reoperation rate. Yet, adjustable suture surgery has not gained universal acceptance, partly because Level 1 evidence of its advantages is lacking, and partly because the learning curve for accurate decision making during suture adjustment may span a decade or more. In this review we describe the indications, techniques, and published results of adjustable suture surgery. We will discuss the option of 'no adjustment' in cases with satisfactory alignment with emphasis on recent advances allowing for delayed adjustment. The use of adjustable sutures in special circumstances will also be reviewed. Consistently improved outcomes in the adjustable arm of nearly all retrospective studies support the advantage of the adjustable option, and strabismus surgeons are advised to become facile in the application of this approach.Eye advance online publication, 15 July 2011; doi:10.1038/eye.2011.167.

Medical and Biotech [MESH] Definitions
Implants used in arthroscopic surgery and other orthopedic procedures to attach soft tissue to bone. One end of a suture is tied to soft tissue and the other end to the implant. The anchors are made of a variety of materials including titanium, stainless steel, or absorbable polymers.
Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (Miller, Walsh & Hoyt's Clinical Neuro-Ophthalmology, 4th ed, p641)
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
A biocompatible polymer used as a surgical suture material.
The surgical closure of the incompetent cervix uteri with suture material.
PURPOSE: To evaluate the clinical characteristics of strabismus in children undergoing bilateral cataract surgery. METHODS: We retrospectively reviewed the medical records of 56 children undergoing bi...
Background: Both over- and undercorrection can occur in up to 10-15% of strabismus surgeries. Use of adjustable suture technique and an intraoperative awake test may decrease the incidence of over-...
PURPOSE:To identify possible factors associated with the development of a conjunctival cyst after surgery for strabismus. METHODS:A descriptive, longitudinal, and retrospective study was done includin...
BACKGROUND: Visible strabismus has been shown to have adverse psychosocial consequences. It remains controversial if esotropia or exotropia is perceived more negatively. The aim of this study was to d...
Correction of adult strabismus is not a cosmetic procedure but one that restores normality to an individual's appearance that has been altered by a disease process. Two fundamental principles underpin...
The purpose of this study is to compare the efficacy of 5 % vs. 1.25 % povidone-iodine (PI) as preoperative antiseptic prior to strabismus surgery in children as a prophylaxis of endophtha...
