Evaluation of Jensen procedures by saccades and diplopic fields
W. E. Scott, D. B. Werner and L. Lennarson
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 less than 40% normal abduction saccadic function. The
patients' conditions were evaluated preoperatively and postoperatively by
prism cover test. Versions, forced ductions, saccadic velocities, and
diplopic 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
(less than 40% normal saccadic function).
