The Effect of Jensen Procedure with Medial Rectus Recession in Lateral Rectus Palsy

ABSTRACT

Jensen procedures with medial rectus recession were performed on 13 eyes of 10 patients with lateral rectus palsy caused by trauma. The cases were reviewed retrospectively to assess efficacy of the procedure and long-term stability. After the average 10.2 months of follow-up period, the 7 patients on whom unilateral Jensen procedures and medial rectus muscle recession were performed improved an average of 45.0 delta, and the 3 patients who underwent bilateral Jensen procedures and medial rectus muscle recession improved an average of 82.3 delta. Preoperatively, 12 eyses demonstrated abduction of -4, and 1 eye demonstrated abduction of -1. Postoperatively, abductions of eyes are as follows 3 eyes -4, 5 eyes -3, 3 eyes -2, and 2 eyes -1. 10 eyes (76.9%) showed improved abduction of lateral rectus muscle, but 3 eyes(23.1%) were not changed. 4 patients(40.0%) acquired a functional area of diplopia free vision, but 6 patients(60.0%) did not, 1 patient developed diplopia postoperatively. No significant cases of vertical deviation were created. One showed anterior segment ischemia, but recovered without complications. Based on these results, the Jensen procedure combined with medial rectus recession is effective in correcting palsies of the lateral rectus muscle that is not recovered.
