Abstract:
This study was conducted to assess the amount of superior oblique tuck surgery and the corrected amount of vertical strabismus and head tilt after superior oblique tuck surgery in patients with unilateral superior oblique palsy.Superior oblique tuck surgery was performed on 13 patients with unilateral superior oblique palsy, which corresponded to the second or the third type with hypertropia of 25 PD (prism diopters)or less of Knapp classification. The mean preoperative vertical deviation was 17.8 PD and the mean postoperative vertical deviation was 8.8 PD:the mean corrected amount of vertical deviation was 9.0 PD.Head tilt, which had been observed in 10 (77%)patients preoperatively, improved by over 5 degrees, head tilt in 5 (50%)of them postoperatively.The results suggest that superior oblique tuck surgery may as well be combined with ipsilat eral inferior oblique weakening or with ipsilateral or contralateral vertical rectus muscle surgery in unilateral superior oblique palsy patients with the amount of vertical deviation of 15 PD or more.
