Bimedial rectus recession using the anchored hang-back technique

Area of Science:

• Ophthalmology
• Strabismus Surgery
• Surgical Techniques

Background:

• Conventional hang-back recession in strabismus surgery offers benefits like reduced scleral perforation risk and easier suturing.
• However, conventional hang-back recession has drawbacks, including muscle collapse, unpredictable effective recession, and difficulty in precise vertical alignment adjustments for A- and V-patterns.

Purpose of the Study:

• To introduce and evaluate a modified hang-back recession technique: anchored hang-back recession.
• To assess the efficacy and predictability of this new technique in correcting strabismus.

Main Methods:

• A modified hang-back recession technique was developed, termed anchored hang-back recession.
• The technique was applied to 60 consecutive cases requiring bimedial rectus recession.
• Outcomes were analyzed to evaluate the effectiveness and predictability of the modified procedure.

Main Results:

• The anchored hang-back recession technique demonstrated advantages over conventional methods.
• Specific results regarding predictability, adjustability, and correction of vertical deviations were observed in the 60 cases.
• The modified technique appears to mitigate some disadvantages of the standard hang-back recession.

Conclusions:

• The anchored hang-back recession is a viable modification offering improved outcomes in strabismus surgery.
• This technique enhances predictability and adjustability, addressing key limitations of previous methods.
• Further studies may explore its application in a broader range of strabismus cases.
