Abstract:
AIM: To investigate the surgical methods of Helveston syndrome.
METHODS: Fifteen cases ( 30 eyes ) with Helveston syndrome were studied. Surgical method was selected according to the degree of superior oblique muscle overaction and dissociated vertical deviation (DVD).
RESULTS: Binocular superior oblique intrathecal tenectomy was performed in 8 patients (16 eyes). Follow-up period after surgery was 1-3a. Those 8 patients got A-sign correction, of which 3 patients (6 eyes) got DVD vanished and 5 patients (10 eyes) got DVD alleviation. None of the 8 cases needed another operation for DVD. Binocular superior rectus recession and binocular lateral rectus recession with vertical offsets was performed in 4 patients (8 eyes). Follow-up period after surgery was 1-3a. The 4 patients got A sign correction and with orthophoria, of which 1 patient ( 2 eyes ) got DVD vanished and 3 patients ( 6 eyes) got DVD alleviation. None of the 4 cases needed another operation for DVD. Binocular lateral rectus recession and vertical offsets was performed in 3 patients (6 eyes). Follow-up period after surgery was half a year, with orthophoria, no A sign, DVD weakened, and no second operation was needed.
