Abstract
Aim: To evaluate the outcome of inferior transposition of the horizontal recti in patients with reduced down gaze in one eye.
Methods: The case notes of 9 patients who underwent inferior transposition of horizontal recti were retrospectively reviewed. The pre- and post-operative orthoptic findings are presented and the outcome of surgery discussed.
Results: Indication for surgery was a reduction in downgaze, caused by trauma in 5 cases, fourth nerve palsy in 3 cases and in 1 case decompensated congenital fourth nerve palsy in association with a facial fracture. The median vertical deviation in the primary position was 14Δ pre-operatively (range 4-25Δ) reducing to 3Δ post-operatively (range 0-13Δ). No patient was overcorrected in downgaze. Pre- and post-operative Hess chart scores indicated a reduction in vertical displacement for all patients. Binocular single vision (BSV) scores demonstrated a more centralised field of BSV in all but 1 patient.
Conclusions: Inferior transposition is useful in patients with poor depression in one eye. It improves downgaze, centralises the field of BSV and relieves symptoms of diplopia.
