AIM: To investigate the rebuilding of binocular vision in adult comitant strabismus patients.

METHODS: Twenty-one cases of adult comitant strabismus were examined before operation, 3 days, 6 weeks, 6 months after operation respectively. Three degree binocular vision was tested by Synoptophore and near stereoacuity, crossed disparity and uncrossed disparity were tested by Yan Shaoming stereogram.

RESULTS: Sixteen cases had uniocular suppression before operation, among them, 6 cases removed uniocular suppression 6 weeks postoperatively, the difference was significant(P<0.05); Five cases had synoptophore binocular vision before operation and it increased to 11 cases 6 weeks postoperatively, among them, 7 cases were improved, improved 36.8%, the difference was statistically significant(P<0.05); Three cases had near stereopsis before operation and it increased to 7 cases 6 weeks postoperatively, among them, 4 cases were improved, improved rate 22.2%, the difference was statistically significant(P<0.01); Three cases had normal crossed disparity before operation and it increased to 7 cases 6 weeks postoperatively, among them, 4 cases were improved, improved 22.2%, the difference was statistically significant(P<0.01); Four cases had normal uncrossed disparity before operation and it increased to 7 cases 6 weeks postoperatively, among them, 3 cases were improved, improved 17.6%, the difference was statistically significant(P<0.01).

CONCLUSION: Binocular vision has been improved in different degrees postoperatively for adult comitant strabismus, mainly in simultaneous perception and synoptophore fusion, but stereopsis is hard to be built, especially the distance stereopsis; it is not clever to neglect the reconstruction of binocular vision just because of missing right time of surgery.
