目的：探讨单眼视野丢失严重程度对原发性闭角型青光眼、原发性开角型青光眼和正常眼压性青光眼患者双眼视野缺损的影响。

方法：根据双眼单眼视野缺损的阶段，将120例青光眼患者和30例健康参与者分为正常、早期、中度或重度四个阶段。通过整合视野和Esterman双眼视野评估确定双眼视野。在组内和组间比较单眼和双眼视野参数。

结果：对于一只眼睛处于正常或早期阶段而另一只眼睛处于严重阶段的患者，双眼综合视野平均偏差分别为-2.8±1.1、-5.5±1.9dB，以及Esterman的平均得分分别为99.1%±1.7%和95.6%±4.7%。当双眼发展为中度或重度损伤(中度/中度，中度/重度或重度/重度)时，双眼综合视野平均偏差低于-6dB，中度/中度和中度/严重损伤组Esterman的平均得分分别为94.2%±6.0%、94.3%±4.9%，但当双眼处于重度损伤阶段时，Esterman的平均得分迅速从大于90%下降到68.4%±26.3%。

结论：如果一只眼睛处于正常或早期阶段，双眼视野可以保持相对完整。当双眼进展到中度或重度阶段时，通过双眼综合视野平均偏差测量的双眼视野缺损是显著的，并且仅当双眼进入严重阶段时才检测到显著的Esterman双眼视野缺损。

METHODS: According to the stage of binocular monocular field loss, 30 healthy and 120 glaucoma patients participants were classified as normal, early, moderate or severe. Binocular vision was determined by integrating the field of view and Esterman binocular field assessment. The monocular and binocular visual field parameters were compared within and between groups.

RESULTS:For patients with one eye at normal or early stage and the other with severe stage, the mean deviation of binocular comprehensive visual field was -2.8±1.1dB and -5.5±1.9dB, respectively, and Esterman's average score were 99.1%±1.7% and 95.6%±4.7%, respectively. When both eyes developed moderate or severe injury(moderate/moderate, moderate/severe or severe/severe), the mean deviation of binocular comprehensive visual field is lower than -6dB, and the Esterman average score of moderate/moderate group and moderate/severe group was 94.2%±6.0% and 94.3%±4.9%, respectively. However, when both eyes in the stage of severe injury, the average score of Esterman's rapidly decreased from more than 90% to 68.4%±26.3%.

CONCLUSION: If one eye is in a normal or early stage, the binocular vision can remain relatively intact. When the binocular progression to the moderate or severe stage, the mean deviation of binocular visual field defects measured by the binocular comprehensive visual field is significant, and only when the binocular progression to the severe stage, significant Esterman binocular visual field defects are detected.
