摘要:
目的　观察融像性聚散功能障碍者在观看３Ｄ影像后动眼参数的变化情况，并探讨其与视疲劳的相关性。方法　本研究为病例对照研究，选取３７名青年受试者，按其融像性聚散能力分为２组：视功能正常（ｎｏｒｍａｌｖｉｓｕａｌｆｕｎｃｔｉｏｎ，ＮＶＦ）组２１人，融像性聚散功能障碍（ｆｕｓｉｏｎａｌｖｅｒｇｅｎｃｅｄｙｓｆｕｎｃｔｉｏｎＦＶＤ）组１６例。两组受试者观看４０ｃｍ处３Ｄ影像前和观影１ｈ后分别行动眼参数的测量，包括单眼调节幅度、梯度性调节性集合／调节（ａｃｃｏｍｍｏｄａｔｉｏｎｃｏｎｖｅｒｇｅｎｃｅ／ａｃｃｏｍｍｏｄａｔｉｏｎ，ＡＣ／Ａ）值、观看距离所对应的近距隐斜量、融像幅度以及视疲劳的主观问卷。结果　两组人观看３Ｄ影像后均出现视疲劳，ＦＶＤ组视疲劳问卷得分高于ＮＶＦ组（Ｐ＝０．０１２）。ＮＶＦ组观影前后的单眼调节幅度分别为（１２．４９±１．３７）Ｄ、（１２．０７ ±１．３１）Ｄ；近距隐斜量分别为－３．０２△ ±１．７０△、－４．７１△ ±１．５１△，差异均有统计学意义（均为Ｐ＜０．００１）；融像幅度分别为５１．８１△ ±６．９３△、５０．９０△ ±７．５７△，差异无统计学意义（Ｐ＝０．０５９）。ＦＶＤ组观影前后的单眼调节幅度分别为（１２．３３±１．７０）Ｄ、（１１．６６±１．８１）Ｄ；近距隐斜量分别为－３．１３△ ±２．３１△、－４．４１△ ±２．５９△，差异均有统计学意义（均为Ｐ＜０．００１）；融像幅度分别为３７．７５△ ±６．７２△、３４．２５△ ±７．３７△，差异有统计学意义（Ｐ＜０．００１）。ＮＶＦ组与ＦＶＤ组观影前后ＡＣ／Ａ均未发生显著性变化（Ｐ＝０．６３１，Ｐ＝０．２４５）。观影前后单眼调节幅度改变量、近距隐斜量改变量、ＡＣ／Ａ改变量在ＮＶＦ组和ＦＶＤ组间差异均无统计学意义（均为Ｐ＞０．０５），且所有受试者观影前后近距隐斜量改变量与视疲劳程度无相关性（ｒｓ＝０．０２１，Ｐ＝０．９０４）。而观影前后融像幅度的改变量在ＮＶＦ组－１．００△（－２．５０△ ～１．５０△）和ＦＶＤ组－３．５０△（－５．００△ ～－２．２５△）间差异有统计学意义（Ｐ＝０．００１）。结论　观看３Ｄ影像会导致视疲劳及单眼调节幅度、近距隐斜量和融像幅度的变化；融像性聚散障碍者较视功能正常者观影后融像幅度下降更明显，视疲劳更严重。融像幅度可作为预测和评估观影像后视疲劳程度的一项指标。
Abstract:
Objective To investigate the changes of ocular motor parameters and visual fatigue in fusional vergence dysfunction after viewing 3D images and its correlation with visual fatigue. Methods A case control study. A total of 37 young adults were enrolled. According to fusional vergence ability , they were divided into normal visual function ( NVF) group ( n = 21 ) and fusional vergence dysfunction ( FVD) group ( n = 16 ) . Before and after viewing 3D images at 40 cm for I hour, monocular accommodation amplitudes , near heterophoria, AC/A ratio . fusional amplitude and subjective symptoms were examined , respectively. Results Viewing 3D images causes subjective visual fatigue in both groups and the score of visual fatigue was sigruficantly higher in FVD group than NVF group ( P = 0. 012 ) . In NVF group , the monocular accommodation amplitudes before and after viewing 3D images were ( 12. 49 + 1. 37 ) D and ( 12. 07 + 1. 31) D . near heterophoria were ( - 3. 02 + 1. 70) u and ( - 4. 71 + 1. 51) A ( all P < 0. 001 ) , fusional amplitude were (51. 81 +6. 93) A and ( 50. 90 +7. 57) u (P = 0. 059 ) . In FVD group , the monocular accommodation amplitudes before and after viewing 3D images were ( 12. 33 + 1. 70 ) D and ( 11. 66 + 1. 81 ) D.near heterophoria were ( - 3. 13 + 2. 31 ) u and ( - 4. 41 +2. 59) n .fusional amplitude were ( 37. 75 + 6. 72 ) n and ( 34. 25 + 7. 37 ) n ( all P < 0. 001) , while the AC/A didn ’ t show significant difference in both groups. Comparing with FVD group , the change of monocular accommodative magnitude , near heterophoria and AC/A in NVF group didn ’ t show statistically significant difference ( all P > 0. 05 ) and there was no correlation between the change near heterophoria and score of visual fatigue for all subjects ( rs = 0. 021 .P = 0. 904 ) . While the change of fusional amplitude in NVF group -1. OOu ( - 2. 50 \ t0 1. 50u ) and FVD group - 3. 50n ( _ 5. OOn to - 2. 25 u ) were significantly different ( P = 0. 001 ) . Conclusion Viewing 3D images can cause subjective visual fatigue and leads to the changes of monocular accommodation amplitudes ,near heterophoria and fusional amplitude. The more sigruficant decrease of fusional amplitude and visual fatigue occurre in fusional vergence dysfunction subjects. It is shown that fusional amplitude can be utilized as one of objective indexes to predict and evaluate visual fatigue.
