• A total of 15 eyes of 13 patients with lateral rectus palsies underwent Jensen procedures; one eye had a medial rectus recession and lateral rectus resection. It was arbitrarily decided to perform a Jensen procedure for patients with < 40% normal abduction saccadic function. The patients' conditions were evaluated preoperatively and postoperatively by prism cover test. Versions, forced ductions, saccadic velocities, and dipiopic field examinations were done. Postoperatively, all patients showed improved saccadic function; 12 of 13 patients acquired a functional range of diplopia-free vision; and 11 of 13 patients had aligned eyes with a good head position. By retrospective analysis we determined that the Jensen procedure gives good results for patients with severe lateral rectus palsy (< 40% normal saccadic function).
