The use of press-on Fresnel prisms is described as a simple inexpensive technique to rehabilitate patients with homonymous hemianopsia. The optical principle of prismatic displacement from the blind to the seeing fields is detailed herein. Forty-one patients were evaluated over a 10 year period. Twenty per cent benefited from the prism. Many of those who found limited or little value from their use expressed appreciation that something had been tried in order to improve visual function. Those patients with good acuity and an otherwise normal neurological status are the best candidates. Proper motivation and instruction are essential.
使用压贴式菲涅尔棱镜被描述为一种用于康复同向性偏盲患者的简单且廉价的技术。本文详细阐述了从盲视野到可见视野的棱镜移位光学原理。在10年期间对41名患者进行了评估。20%的患者从棱镜中受益。许多认为其作用有限或几乎没有价值的患者对曾尝试采取措施改善视觉功能表示感激。视力良好且神经状态正常的患者是最佳候选者。正确的动机和指导至关重要。
