PD prism diopters, ASI anterior segment ischemia

The angle of deviation pre- and postoperatively was estimated by cover–uncover test with far target at 3 m. Post-op angle ≤ 10 PD was considered a success

Complete sixth nerve palsy was defined as the inability to abduct more than the midline (primary position). The abduction was scored as: −8 complete inability for abduction, −4 partial ability for abduction, up to primary position, 0 ability for full abduction

The postoperative follow up was undertaken at: 1st day, 1st week, 1st month, 6 months, 12 months

Patients with residual esotropia appeared with no problems in their everyday life. They were helped with prismatic correction incorporated into far-distance glasses, as well as the patient with the vertical deviation
