【摘要】：目的 探討聚散靈敏度與融像性聚散的相關(guān)性,同時了解被檢者聚散適應(yīng)量值在此相關(guān)性中的作用,為臨床上功能性雙眼視覺異常的診斷提供更直接、更有意義的指標。 方法 隨機選取50名20-28周歲在校近視大學生,應(yīng)用電腦驗光儀和綜合驗光儀行規(guī)范主覺驗光后,在被檢者屈光不正全矯的基礎(chǔ)上利用FVG法測量被檢者的視近隱斜量值,隨后分別進行聚散靈敏度檢測和融像性聚散檢測,最后測量其經(jīng)過兩種檢測后的棱鏡適應(yīng)量值,利用SPSS13.0統(tǒng)計軟件對相關(guān)數(shù)據(jù)進行分析,確定聚散靈敏度檢測數(shù)據(jù)與融像性聚散檢測數(shù)據(jù)的相關(guān)性,同時確定被檢者棱鏡適應(yīng)量值與此相關(guān)性的關(guān)系。 結(jié)果 1.視近隱斜偏高組(6△EXO)和視近隱斜正常組(0-6△EXO)的聚散靈敏度檢測結(jié)果存在顯著性差異(t=-0.552,P=0.033),并且BI方向和BO方向的恢復(fù)點數(shù)值也都存在顯著性差異(t=0.115,P=0.023；t=-0.146,P=0.031)。 2.運用Spearman rank相關(guān)分析法發(fā)現(xiàn)被檢者BI方向的模糊點和破裂點與聚散靈敏度無相關(guān)性(r=0.215, P=0.253; r=0.336, P=0.07),而恢復(fù)點與其聚散靈敏度檢測結(jié)果存在相關(guān)性(r=0.445,P=0.014)。 3.高度近視組(-6.00D)和低度近視組(-6.00D)的BI方向的恢復(fù)點數(shù)值和聚散靈敏度的數(shù)值之間均無顯著性差異(t=-0.521, P=0.610;t=-1.081, P=0.300)。 4.運用方差分析的檢驗方法研究發(fā)現(xiàn),分別測量被檢者在通過聚散靈敏度檢測和融像性聚散檢測后的四點的棱鏡適應(yīng)量值,發(fā)現(xiàn)四者之間不存在顯著性的差異(F=6.294,P=0.325)。 5.融像性聚散檢測達標組與非達標組的棱鏡適應(yīng)量值無顯著性差異(P=0.354)；聚散靈敏度檢測達標組與非達標組的棱鏡適應(yīng)量值也無顯著性差異(P=0.482)。 結(jié)論 可以通過被檢者的恢復(fù)點數(shù)值推測其聚散靈敏度數(shù)值是否異常,可使融像性聚散檢測中的恢復(fù)點數(shù)值得到充分的使用,從而減少了專項的聚散靈敏度檢查,使雙眼視覺異常的診斷更為簡便、直接,同時確定被檢者的棱鏡適應(yīng)量值與兩種檢測之間是否存在相關(guān)性并無直接關(guān)系。
[Abstract]:Aim to investigate the correlation between the sensitivity of dispersion and fusion dispersion, and to understand the role of fitness value in the correlation, so as to provide a more direct and meaningful index for the diagnosis of functional binocular visual abnormalities in clinic. Methods Fifty 20-28-year-old myopic college students were randomly selected. After using computer optometry and comprehensive optometry, the visual near-occult deviation of the subjects was measured by FVG method on the basis of full correction of refractive errors of the subjects, and the visual near-occult deviation of the subjects was measured by using the computer optometry and the comprehensive optometry. At last, the prism adaptation value after two kinds of detection is measured, and the correlation data are analyzed by SPSS13.0 statistical software, and the correlation data are analyzed by the statistical software of SPSS13.0, then the fusion sensitivity detection and fusion dispersion detection are carried out respectively. The correlation between the measurement data of dispersion sensitivity and the data of fusion dispersion detection was determined, and the relationship between the adaptation value of prism and the correlation was also determined. Outcome 1. There was a significant difference in the sensitivity between the groups of high near occlusal deviation (6 EXO) and normal visual near aphasia (0 / 6 EXO) (t = 0.552, P = 0.033), and there was a significant difference between the two groups (t = 0.552, P = 0.033). There was also a significant difference in the recovery point values between BI and BO (t = 0.115, P = 0.023). T = 0.146, P = 0.031). 2. By means of Spearman rank correlation analysis, it was found that there was no correlation between the BI direction fuzzy point and the rupture point and the dispersion sensitivity (r = 0.215, P = 0.253). However, there was a correlation between the recovery point and the sensitivity (r = 0.445, P = 0.014), but there was a significant correlation between the recovery point and the sensitivity (r = 0.445, P = 0.014). 3. There was no significant difference between high myopia group (- 6.00D) and low myopia group (- 6.00D) in BI recovery point and divergence sensitivity (t = 0.521, P = 0.610, P = 1.081, P = 0.300). There was no significant difference between high myopia group (- 6.00D) and low myopia group (- 6.00D) in recovery point value and divergence sensitivity value (t = 0.521, P = 0.610). 4. By means of ANOVA test method, it was found that there was no significant difference among the four points of prism adaptation after the detection of dispersion sensitivity and fusion dispersion (F = 6.294, P < 0.05, P < 0.01, P < 0.01), and that there was no significant difference between the four groups. (P = 0.325). 5. There was no significant difference in the prism adaptation value between the two groups (P = 0.354), and there was no significant difference in the prism adaptation value between the two groups (P < 0. 482), and there was no significant difference in the prism adaptation value between the standard-reaching group and the non-standard group (P < 0. 482). Conclusion it is possible to speculate whether the value of dispersion sensitivity is abnormal according to the recovery point value of the subject, which can make full use of the recovery point value of the fusion dispersion detection, and thus reduce the special detection of the dispersion sensitivity. It makes the diagnosis of binocular vision abnormality more simple and direct, and there is no direct relationship between the prism adaptation value of the subject and whether there is a correlation between the two tests.
