Short Loop Modification of the Semiadjustable Suture Strabismus Procedure for Optional Adjustment

Area of Science:

• Ophthalmology
• Surgical Techniques
• Strabismus Surgery

Background:

• The standard semiadjustable suture technique in extraocular muscle surgery involves exposed sutures.
• Adjustments in the standard technique can be complex and require significant manipulation.

Purpose of the Study:

• To present a modified semiadjustable suture technique for extraocular muscle recession.
• To allow for optional postoperative adjustment while minimizing manipulation when not needed.

Main Methods:

• A modified technique using short, buried suture loops under the conjunctiva was employed.
• A temporary tracing suture was used to facilitate retrieval of the buried loop for adjustment.

Main Results:

• The modified technique was used in 57 rectus extraocular muscles across 53 patients.
• Postoperative adjustment was performed in 39.6% of cases; the remaining cases required only suture removal.
• Minor complications included conjunctival hyperemia and dehiscence, all responsive to topical treatment. No muscle slippage occurred.

Conclusions:

• The short loop modification enables postoperative adjustment with reduced manipulation for most patients.
• This technique offers a safe alternative with no major complications related to conjunctival or muscle healing.
