Adult intermittent alternating exotropia - unilateral recess/resect vs bilateral surgery? Looking for real experiences

Hi everyone,

I'm a 27-year-old male with intermittent alternating exotropia.

My situation is a bit specific:

  • Distance deviation: 30 PD
  • Near deviation: 15 PD
  • Left eye drifts outward in normal relaxed daily life.
  • If I consciously focus, my eyes appear almost perfectly aligned.
  • I have no double vision.
  • Vision is good (Right eye 6/6, Left eye 6/9, sometimes 6/6).
  • I can voluntarily control the deviation for short periods.

Interestingly, if I intentionally switch fixation to my left eye, my right eye can drift outward (alternating exotropia), but this does not happen in my normal daily life.

I've had three surgical opinions:

  • Two strabismus surgeons recommended left eye only:
    • Left Medial Rectus Resection (5 mm)
    • Left Lateral Rectus Recession (7 mm)
  • One surgeon recommended one muscle in each eye (bilateral surgery).

The two-surgeon consensus is making me lean toward unilateral surgery.
