视野缺损干扰色素性视网膜炎患者的自由行动，影响生活质量；在老龄化社会中，这种疾病的患病率正在增加。患有疾病进展的患者可能需要视觉辅助设备；然而，目前还没有这样的设备。我们使用视网膜投影眼镜系统，QD 激光眼镜，其中包括眼镜架内的投影仪，以绘制由连接的带有广角镜头的便携式相机拍摄的图像。使用麦克斯韦视图光学系统将图像投影到视网膜上，该系统不受屈光不正或入射光量的影响。使用 QD 激光眼镜进行的 Goldmann 视野检查和图形识别测试显示，在我们使用针孔系统开发的有限视野模型中，视野面积和角度有所增加，并且缩短了识别一张纸中图形数量的时间，该模型是通过使用针孔系统模拟 19 名健康成年人患有色素性视网膜炎的隧道视觉而开发的。该设备支持视觉质量。此外，健康成年人使用的视野缺陷模型有助于在研究开发阶段验证该设备，以阐明改进该设备的优点和未来目标。
Visual field defects interfere with free actions and influence the quality of life of patients with retinitis pigmentosa; the prevalence of this disease is increasing in aging societies. Patients with progressive disease may require visual aids; however, no such devices are currently available. We utilized a retinal projection eyewear system, QD laser eyewear, which includes a projector inside the spectacle frame, to draw the image taken by a connected portable camera with a wide field lens. The images are projected onto the retina using a Maxwellian view optical system, which is not influenced by refractive error or the amount of incident light. Goldmann perimetry and figure recognition tests with the QD laser eyewear showed increased visual field areas and angles, and shortened the time for recognition of the number of figures in a sheet, in a limited visual field model that we developed by using a pin-hole system to simulate the tunnel vision of retinitis pigmentosa in 19 healthy adults. The device supported the quality of vision. Additionally, the visual field defect model used in healthy adults was useful for validating the device in the development stage of the study, to clarify both advantages and future goals for improving the device.
