  1. SRT superior rectus transposition, a augmentation was performed in some patients only, as per author preference, ET esotropia, AHP abnormal head posture, HOT hypotropia, HT hypertropia, N/A not available, b average improvement of the item in the whole study population as specific values in individual groups were not clarified
