Long-term follow-up of Jensen procedures.

Jensen procedures were performed on 29 eyes of 26 patients with lateral rectus palsy between January 1972 and July 1985. The cases were reviewed retrospectively to assess efficacy of the procedure and long-term stability. The patients were evaluated preoperatively with prism cover test, versions, forced auctions, saccadic velocities, and diplopia fields. All patients were observed preoperatively for at least 6 months and had no further recovery of function. Eighteen eyes had less than 20% of normal abduction saccadic velocity; nine eyes had 20% to 40%; two could not be assessed with saccadic velocities. The procedure was a Jensen's union combined with a medial rectus recession on adjustable suture. The average follow-up was 4 years. Twenty-four patients had good head positions and fusion with a functional area of single binocular vision, averaging 41 horizontally. All patients demonstrated improved saccadic velocities, with similar improvement for those beginning with less than 20% abduction saccadic velocity and those with 20%-40%. A single case of anterior segment ischemia is reported.
