1 To examine visual function with synthetical optometry and synoptophore.

2 Using the synoptophore to examine the binocular function.

3 Conclusion:The modified synoptophore apparatus with semi reflective mirror is a reliable and adaptable method for measuring AC/A ratios.

4 To evaluate the effect of Synoptophore training for the deterioration of postoperative intermittent exotropia.

5 Methods The rondon-Dot stereogram and synoptophore were used to examine, the acuity threshold, fusion field and response speed of distant and near stereopsis in 102 subjects with normal aged vision.

6 Conclusion Antisuppression therapy by flicker stimulation with synoptophore is effective.

7 Methods Analyse diplopia image by red lens. Make examination using synoptophore, CT or MRI etc.

8 All patients showed no cyclotropia and normal binocular vision function was obtained with synoptophore before and after surgery.

9 Methods: To examine visual function with synthetical optometry and synoptophore.

10 Binocular images(FFA or OCT), binocular fusion sense, fusion range, and the nature of stereopsis were examined with a synoptophore.

11 All of the patients underwent clinical examinations including three-prism and eye movement, and synoptophore examination was performed for the cooperative children.

12 Conclusion The diagnosis was based on eye position, movement and synoptophore examination.

13 Subjective cyclodeviations and binocular vision function were assessed by synoptophore.

14 CONCLUSION: An early operation for the intermittent exotropia and the instruction of synoptophore after the operation are suggested for rebuilding binocular single vision.

15 The deviation degree and visual function examination were performed by the synoptophore and prism pre- and post-operation in 128 concomitant strabismus patients.
