[Cyclotropia in macula translocation. Possible eye muscle surgery solutions]

Area of Science:

• Ophthalmology
• Ophthalmic Surgery
• Strabismus Surgery

Context:

• Macular translocation is a surgical procedure for age-related maculopathy.
• Counter-rotation of external eye muscles is often required.
• Maintaining anterior segment perfusion is critical when combining muscle procedures.

Purpose:

• To evaluate the excyclorotatory effects of four different combined surgical approaches.
• To analyze the outcomes of 29 operations for macular translocation.

Summary:

• Combined procedures on extraocular muscles, including recti and oblique muscles, achieved mean excyclorotatory effects exceeding 20 degrees.
• Specific techniques like partial transposition of all four recti with oblique muscle surgery yielded 21.6 degrees.
• Other combinations, such as vertical transposition of horizontal recti or oblique muscle advancements, resulted in excyclorotation of 22 to 37 degrees.

Impact:

• Demonstrates the efficacy of combined extraocular muscle surgery for achieving significant counter-rotation.
• Provides insights into surgical options for correcting horizontal or vertical angles in a single step.
• Highlights considerations for dosage, induced inconcomitancies, and operative time in complex ophthalmic procedures.
