摘要
目的 研究随机点立体图检测６０例正常人立体融合功能的作用。方法 采用随机点同视机立体图Ｒ．Ｄ．Ｓ．Ｓ）检测６０例１０～２９岁正常人融合范围，心立体感消失或出现作为判断融合破裂的标志，计算内外融合比值。结果；（１）应用Ｒ．Ｄ．Ｓ．Ｓ测定融合范围；最大为８００″组，－９．４△～＋２４．３△，最小为６０″组，－７．４△～＋１７．０△，平均范围－８．３±０．７△～＋２０．９±２．７△。
To study third degree fusion function by using synoptophone of R. D. S. Methods: Fusion range wastested by using synoptophone of (R. D. S. S. ). The fusion depends on whether stereopsis appeared or not. We calculated theraio of in-fusion and out-fusion. Results: The average range of fusion was - 8. 3 t 0. 7n ~ 20. 9 t 2 .7n. Statisticalcomparison of in-fusion indicated the siedcant chrence between two groups (> 400) seconds group and <100 secondsgroup), (P < 0. 05): And the ratio of in-fusion and out-infusion was 2. 7 ~ 2. 3' l. Conclusion There was difference between second degree Ihaion and third degree fusion in conception and connotahon. Examination of fusion ranges with R. D.S. S., was virtually a test of Panum's fusional space. The higher the stereoacnities, the hroader the fusion ranges.Panum s fusional space is supared to include static and motive spaces.
