| Abstract |
|
In 33 patients with congenital superior oblique palsy, we examined whether patients fixed with paretic or nonparetic eye in primary, head tilted positions to the right and left, and whether they could fuse in the characteristic head tilt postion or not. Of the 33 patients, 27 had horizontal deviation, 21 had vertical deviation and 17 had both horizontal and vertical deviation. There were 10 'V' patterns in 13 bilateral cases. In unilateral cases, both the paretic and nonparetic eye could be the fixating eye in primary position. There was a tendency to fix with right eye in the left head tilt, with left eye in the right head tiltin both the unilateral and bilateral cases. Twelve ot the 13 patients could not fuse with Worth 4 dot test preoperatively even in head tilted position. |
