Postoperative Reconstruction Of Binocular Vision In Patients With Congenital Superior Oblique Palsy

Objective:To compare preoperative and postoperative binocular vision in patients with congenital superior oblique palsy and study whether the age factor and strabismus extent has an effect on postoperative reconstruction of binocular vision.Methods:Thirty-eight patients in my hospital came from January, 2005 to June,2006,which were 31 monocular congenital superior oblique palsies and 7 binocular palsies,that boys occupied 32 and girls occupied 6.Their age is 4 to 12 years.All data's horizontal deviation was≤10~Δ.Their hyperdeviation in primary position was 5~Δto 40~Δ.Binocular vision was detected by synoptophore.Near stereoacuity was detected by Titmus.Results:The postoperative eyes had better simultaneous perception,fusion,distance stereoacuity than the preoperative eyes.There was statistically significant difference between postoperative eyes and preoperative eyes(p＜0.05).While the statistically significant difference is below 0.01 between them at near stereoacuity.There was no statistically significant difference between operation age and stereoacuity (p＞0.05).The postoperative stereoacuity was worse at high dimensionality eyes than the low.Conclusions:The operation improved the binocular vision in patients with congenital superior oblique palsy.The three grades of binocular vision were better after operation than before operation. Operation age had an effect on postoperative binocular vision.But it had no statistically significance difference.The binocular vision became worse along with increased dimensionality.
