This study describes the binocular eccentric gaze direction (EGD) of 434 patients with binocular central field loss and presents a comparison with other studies on eccentric gaze behavior.
We reviewed the records of 434 patients with bilateral central scotomas. Eligible patients had not received eccentric viewing training and demonstrated a spontaneously developed eccentric gaze behavior. Data were collected on monocular and binocular EGD, visual acuity, and underlying ocular pathology. Findings concerning the EGD were compared with other studies that evaluated gaze behavior in patients with central field loss.
In the group of 434 patients, age-related macular disease was the most frequent pathology (77%). The majority of these patients demonstrated a binocular EGD (bEGD) to the right (50%). In 25% of the patients, a superior bEGD was found. Less often, a bEGD to the left (14%) and to inferior (11%) were encountered. Review of the literature indicates that the majority of patients developed a monocular EGD in the superior direction.
This is a study on bEGD behavior in a large population of patients with bilateral central scotomas. The bEGD was guided by the gaze of the better-seeing eye. The preference for a bEGD to the right differs from findings of previous studies. Review of the literature suggests that not only the ocular pathology but also the method of investigation is most likely to influence the observed EGD. Most studies evaluated the location of the preferred retinal locus using a monocular technique; this may not reflect an individual's actual binocular behavior as it relates to activities of daily living.
本研究描述了434例双眼中心视野缺损患者的双眼偏心注视方向（EGD），并与其他关于偏心注视行为的研究进行比较。
我们回顾了434例双侧中心暗点患者的记录。符合条件的患者未接受过偏心注视训练，且表现出自发形成的偏心注视行为。收集了单眼和双眼EGD、视力及潜在眼部病理情况的数据。将关于EGD的研究结果与其他评估中心视野缺损患者注视行为的研究进行比较。
在434例患者组中，年龄相关性黄斑病变是最常见的病理情况（77%）。这些患者中的大多数表现出双眼EGD（bEGD）向右（50%）。在25%的患者中，发现有向上的bEGD。较少见的是向左（14%）和向下（11%）的bEGD。文献回顾表明，大多数患者形成了向上的单眼EGD。
这是一项关于大量双侧中心暗点患者bEGD行为的研究。bEGD由视力较好的眼睛的注视方向引导。bEGD向右的偏好与先前研究结果不同。文献回顾表明，不仅眼部病理情况，而且研究方法很可能会影响观察到的EGD。大多数研究使用单眼技术评估首选视网膜位点的位置；这可能无法反映个体与日常生活活动相关的实际双眼行为。
