[Examination of eye position after strabismus surgery in Kawasaki Medical School Hospital].
OBJECTIVE
To examine the factors which affect changes in the position of the eyes following the strabismus surgery.


METHODS
The postoperative position of 240 eyes with concomitant strabismus was examined. The factors which seemed to have an effect on the position of the eyes were enumerated, and a logistic regression analysis of the results was done.


RESULTS
In comparison with esotropia, in exotropia the eyes showed a tendency to return gradually to a normal position. There was no remarkable improvement in stereoscopic vision following strabismus surgery. Based on the standards of the Japanese Association of Strabismus and Amblyopia [the cure standard for strabismus], the results of strabismus surgery were as follows: Grade 1(cosmetically satisfactory) was mainly observed for esotropia, and Grade 3(good) for exotropia. The factors which had a significant effect on the postoperative position of the eyes were as follows: esotropia amblyopia, muscle movement, and operative methods; exotropia: retinal correspondence, operative methods, and the necessity of inferior oblique muscle surgery.


CONCLUSIONS
There was little correction of the position of the eyes. In individual cases, the factors which affect position of eyes were examined, and it was considered necessary to increase the amount of correction. Age is a factor which has an effect, but the effect on esotropia and exotropia is small.
