PURPOSE
To evaluate the degree of three-dimensional (3D) perception and ocular and systemic discomfort in patients with abnormal binocular vision (ABV), and their relationship to stereoacuity while watching a 3D television (TV).
METHODS
Patients with strabismus, amblyopia, or anisometropia older than 9 years were recruited for the ABV group (98 subjects). Normal volunteers were enrolled in the control group (32 subjects). Best-corrected visual acuity, refractive errors, angle of strabismus, and stereoacuity were measured. After watching 3D TV for 20 min, a survey was conducted to evaluate the degree of 3D perception, and ocular and systemic discomfort while watching 3D TV.
RESULTS
One hundred and thirty subjects were enrolled in this study. The ABV group included 49 patients with strabismus, 22 with amblyopia, and 27 with anisometropia. The ABV group showed worse stereoacuity at near and distant fixation (P<0.001). Ocular and systemic discomfort was, however, not different between the two groups. Fifty-three subjects in the ABV group and all subjects in the control group showed good stereopsis (60 s of arc or better at near), and they reported more dizziness, headache, eye fatigue, and pain (P<0.05) than the other 45 subjects with decreased stereopsis. The subjects with good stereopsis in the ABV group felt more eye fatigue than those in the control group (P=0.031). The subjects with decreased stereopsis showed more difficulty with 3D perception (P<0.001).
CONCLUSIONS
The subjects with abnormal stereopsis showed decreased 3D perception while watching 3D TV. However, ocular and systemic discomfort was more closely related to better stereopsis.
目的
评估异常双眼视（ABV）患者观看 3D 电视（TV）时的 3D 感知程度、眼和全身不适及其与立体视锐度的关系。
方法
招募斜视、弱视或屈光参差大于 9 岁的患者入 ABV 组（98 例）。正常志愿者纳入对照组（32 例）。测量最佳矫正视力、屈光不正、斜视角度和立体视锐度。观看 3D TV 20 min 后，进行问卷调查以评估观看 3D TV 时的 3D 感知程度和眼、全身不适。
结果
本研究共纳入 130 例受试者。ABV 组包括斜视患者 49 例、弱视患者 22 例和屈光参差患者 27 例。ABV 组近距和远距固视时立体视锐度较差（P<0.001）。但两组间眼、全身不适无差异。ABV 组 53 例和对照组所有受试者近距立体视锐度均为 60 s 弧或更好，他们报告的头晕、头痛、眼疲劳和疼痛比其他 45 例立体视锐度降低的受试者更多（P<0.05）。ABV 组立体视锐度较好的受试者比对照组更易眼疲劳（P=0.031）。立体视锐度降低的受试者更难以获得 3D 感知（P<0.001）。
结论
观看 3D TV 时，异常立体视患者的 3D 感知降低。然而，眼、全身不适与更好的立体视锐度更密切相关。
