Abstract
Objective To investigate the feature and reasons of differences between arc perimeter strabismometry and triple prism strabismometry Methods There were 250 patients of horizontal concomitant squint involved, 115 cases of esotropia, 52 cases were men while 63 were women, with average age of 18.80±10.87 years old,and there were 135 cases of exotropia, 61 cases were men while 74 were women, with average age of 19.10±9.23 years old.All the patients were examined by arc perimeter strabismometry and Prism plus shaded strabismometry in a short distance of 33cm and a long distance of 6m, datas were treated by spss13.0 Results In the esotropia patients, the conversions of circular degree (°) and prism degree (Δ) were: 33cm: 1°=2.46Δ～2.87Δ, 6m: 1°=2.30Δ～2.87Δ, while in the exotropia patients the conversions were: 33cm: 1 °=2.39 Δ～2.70 Δ, 6m: 1 °=2.10 Δ～2.63 Δ.There were statistically significant between clinic values and theoretical values of short distance and long distance in esotropia and exotropia patients, and Clinic values were statistically significant between esotropia patients and exotropia patients.Conclusions Clinic values by arc perimeter strabismometry are smaller than that by triple prism strabismometry, the diversity between the two methods is enlarged with the increase of angle of strabismus.Clinic values of esotropia patients are greater than that of exotropia patients.The primary causes of the differences between circular degree and prism degree are heterophoria、 fusion faculty and defects of the triple prism itself.关键词
