| Objective The aim of the study was to compare the difference of interocular suppression charact eristics in postoperative concomitant exotropia beteen the patients who have normal stereoscopic function and the control group. Methods Collected 20 postoperative patients with concomitant exotropia by one time from Ju ly 2013 to septemper2014, that stereopsis returned to normal level as well as eye p osition as the strabismus group that included 11 men and 9women from 16 to 31 y ears. selected 20 healthy adults that included 9 men and 11 women from 17 to 30 years as the normal control group randomly. Both of the groups were tested by M atlab program which written by Vision research lab to carry on the binocular balan ce test program. The SPSS 16.0 statistical software was used to deal with the resu lts. The t-Test was used to the two groups accuracy, the One-Way ANOVA method was used to within the accuracy 。 Results 1. The accuracy of blance piont of the strabismus group was F(6,46) = 128.559,P< 0.05, a statistically significant differences. The accuracy of blance piont between s trabismus group and control group was t(11.965) =-4.123., P = 0.002, a statistically signiy cant differences. 2. The accuracy of blance piont contrast of the strabismus group was lower than the control group(P < 0.05), a statistically significant differences. Conclusion Part of the postoperative concomitant exotropia patients can restore automatically whe n they examined by Titmus Stereotest, Randot Stereotest and Frisby Stereotest, they can rearch anormal stereo visual function. Interocular suppression still exist while we use more accurate equipment with balance piont test,The Stereoscopic vision fu nctionof postoperative concomitant exotropia patients could be evaluated more compr ehensively by the combined efforts of the clinical stereoscopic graph and the binocu lar balance test. |
