To investigate the relationship between preferred sleeping position and asymmetric visual field (VF) loss in open-angle glaucoma (OAG) patients.
Retrospective, cross-sectional study.
Six hundred and ninety-two (692) patients with bilateral normal-tension glaucoma (NTG) or high-tension glaucoma were consecutively enrolled. A questionnaire to determine the preferred sleeping position was administered to each patient. Asymmetric VF loss was defined as a difference in mean deviation between the 2 eyes of at least 2 dB. According to these values, the better eye and worse eye were defined. Among the patients with asymmetric VF loss, the numbers preferring the worse eye-dependent lateral decubitus position and the better eye-dependent lateral decubitus position were compared.
Among the enrolled patients, 309 (60.6%) with NTG and 121 (66.5%) with high-tension glaucoma had asymmetric VF between the 2 eyes. Among the 309 NTG patients, 100 (32.4%) preferred the lateral decubitus position. Of these, 66 (66.0%) preferred the worse eye-dependent lateral decubitus position (P = .001). Among the 121 high-tension glaucoma patients, 32 (26.4%) preferred the lateral decubitus position, and of these, 23 (71.9%) preferred the worse eye-dependent lateral decubitus position (P = .013).
Our results suggest that the sleep position habitually preferred by glaucoma patients may be associated with greater VF loss.
探讨开角型青光眼（OAG）患者的睡眠姿势与非对称视野（VF）丧失之间的关系。
回顾性、横断面研究。
连续纳入 692 例双侧正常眼压性青光眼（NTG）或高眼压性青光眼患者。对每位患者进行了一份确定偏好睡眠姿势的问卷。将不对称 VF 损失定义为双眼平均偏差至少相差 2dB。根据这些值，定义了较好眼和较差眼。在具有非对称 VF 损失的患者中，比较了偏爱较差眼侧卧位和较好眼侧卧位的人数。
在纳入的患者中，309 例（60.6%）NTG 患者和 121 例（66.5%）高眼压性青光眼患者双眼之间存在非对称 VF。在 309 例 NTG 患者中，有 100 例（32.4%）偏爱侧卧位。其中，66 例（66.0%）偏爱较差眼侧卧位（P =.001）。在 121 例高眼压性青光眼患者中，有 32 例（26.4%）偏爱侧卧位，其中 23 例（71.9%）偏爱较差眼侧卧位（P =.013）。
我们的结果表明，青光眼患者习惯性的睡眠姿势可能与更大的 VF 损失有关。
