目的:探讨我们的可穿戴夜视辅助治疗对同心周边视野丧失患者的疗效。
方法:前瞻性,单盲,三组,和三期交叉临床研究。
方法:本研究纳入了同心周边视野丧失的患者,在较好的眼睛中,最佳矫正视力(十进制视力)为0.1或更高,和中央视野的存在。HOYAMW10HiKARI®(HOYA公司),我们最初的可穿戴夜视辅助设备,用作具有三种类型相机镜头的测试设备(标准-,middle-,和广角镜头)。在明亮和黑暗的条件下,使用每组的三种镜片类型中的每一种测量水平视野的角度。当每个参与者佩戴夜视辅助装置(断电)时测量基线角度。
结果:该研究包括21名参与者。在明亮的条件下,使用标准角度镜片("标准镜片")时,感知水平视野明显宽于基线设置;中间角度镜片("中间镜片")明显宽于基线设置和标准镜片;广角镜头("广角镜头")明显宽于其他镜片.在黑暗条件下,当使用中间透镜时,感知的水平视野再次比基线设置和标准透镜明显更宽,当使用广角镜头时,感知的水平视野再次比使用其他镜头时更宽。在明亮条件下的对照比在黑暗条件下使用时显著更宽(p<0.001),而在黑暗条件下的标准角度透镜比在明亮条件下使用时显着更宽(p=0.05)。关于中宽镜头,两种照明条件均无统计学意义的结果.
结论:我们的可穿戴式夜视辅助设备配有中角或广角镜头,可为同心周边视野丧失患者提供更宽的视野图像,无论照明条件是明亮还是黑暗。
OBJECTIVE: To investigate the efficacy of our wearable night-vision aid in patients with concentric peripheral visual field loss.
METHODS: Prospective, single blind, three-group, and three-period crossover clinical study.
METHODS: The study included patients with concentric peripheral visual field loss, a best-corrected visual acuity (decimal visual acuity) of 0.1 or higher in the better eye, and the presence of a central visual field. HOYA MW10 HiKARI® (HOYA Corporation), our original wearable night-vision aid, was used as the test device with three types of camera lenses (standard-, middle-, and wide-angle lenses). Under both bright and dark conditions, the angle of the horizontal visual field was measured using each of the three lens types for each group. The baseline angle was measured when each participant wore the night-vision aid (powered off).
RESULTS: The study included 21 participants. Under bright condition, the perceived horizontal visual field was significantly wider than the baseline setup when using the standard-angle lens (\"the standard lens\"); the middle-angle lens (\"the middle lens\") was significantly wider than both the baseline setup and the standard lens; and the wide-angle lens (\"the wide lens\") was significantly wider than the other lenses. Under dark condition, the perceived horizontal visual field was again significantly wider when using the middle lens than the baseline setup and the standard lens, and when using the wide lens, the perceived horizontal visual field was again wider than when using the other lenses. The control in the bright condition was significantly wider (p < 0.001) than when used in the dark condition, while the standard-angle lens in the dark condition was significantly wider (p = 0.05) than when used in the bright condition. In regards to the middle and wide lenses, there was no statistically significant result emerging from either of the illumination conditions.
CONCLUSIONS: Our wearable night-vision aid with a middle-angle or wide-angle lens appears to provide wider visual field images in patients with concentric peripheral visual field loss, regardless of whether the illumination conditions are bright or dark.
