PURPOSE
We studied change of eye position according to surgical amount with strabismus surgery under general anesthesia. METHODS: The 101 horizontal strabismus patients were classified into 5 groups and analyzed according to strabismus type, surgical method, and surgical amount. Group I had less than 7 mm recession in exotropia;, group II, was more than 7 mm recession in exotropia;, group III, was recession and resection in exotropia;, group IV, was less than 5.5 mm recession in esotropia;, group V, was more than 5.5 mm recession in esotropia. We measured eye position, corneal reflex and medial limbus by photographic measurement taken at a distance of 40 cm form the patient in the supine position. RESULTS: The mean amount of convergence in exotropia group I was 8.93+/-2.21PD, exotropia group II was 9.64+/-3.50PD, exotropia group III was 10.77+/-4.11PD. The mean amount of divergence of esotropia group IV was 6.62+/-2.10PD, esotropia group V was 7.88+/-2.90PD. The exotropia and esotropia groups were not statistically different from each other (P>0.05). The correlation coefficient according to surgical amount was 0.18 in exotropia groups, 0.01 in esotropia groups. CONCLUSIONS: The change of eye position according to surgical amount showed a weak positive correlation in exotropia groups, but showed no correlation in esotropia groups. Postoperative mean change in eye position was distributed from 9.26PD to 10.90PD in the exotropia group, from 6.10PD to 7.83PD in the esotropia group with 95% confidence interval and was difficult to expect overcorrection and undercorrection after awaking from anesthesia. |
