Functional muscle insertional changes and strabismus after scleral buckling.

Area of Science:

• Ophthalmology
• Strabismus Surgery
• Retinal Detachment Repair

Background:

• Scleral buckling is a common surgical procedure for retinal detachment.
• Postoperative strabismus is a known complication, but specific causes following this procedure are less documented.

Observation:

• Three patients developed esotropia after undergoing scleral buckling surgery.
• Clinical examination revealed alterations at the rectus muscle insertion sites in all affected patients.

Findings:

• The distance between the limbus and the functional muscle insertion was significantly increased in these cases.
• This anatomical change suggests a link between muscle repositioning and the development of esotropia.

Implications:

• The findings underscore the importance of precisely assessing and managing functional muscle insertions during strabismus surgery.
• This awareness may help prevent or mitigate esotropia following scleral buckling procedures.
• Further research into the biomechanics of muscle insertions after scleral buckling is warranted.
