The authors wish to alert optometrists that an increased awareness of peripheral visual field is possible in selected patients with complete homonymous hemianopsia through the use of ground-in sectorial prisms.
A case series of nine patients prospectively completed activities of daily living (ADL) questionnaires before and after the use of sectorial prism spectacles for the treatment of complete homonymous hemianopsias.
Of the nine enrolled patients, seven reported subjective quantitative improvement in ADL scores on questionnaire responses and two patients did not report improvement.
Patients with homonymous hemianopic visual-field loss may improve their functional vision and activities of daily living through the use of hemianopic prism spectacles. These sectorial prisms--along with proper training--may enhance peripheral awareness through more efficient visual scanning skills.
作者希望提醒验光师，对于某些患有完全性同向偏盲的患者，通过使用内置扇形棱镜，有可能提高其对周边视野的认知。
一个包含9名患者的病例系列前瞻性地完成了在使用扇形棱镜眼镜治疗完全性同向偏盲之前和之后的日常生活活动（ADL）问卷调查。
在纳入的9名患者中，7名患者在问卷回复中报告ADL评分有主观量化改善，2名患者未报告有改善。
患有同向偏盲性视野缺损的患者通过使用偏盲棱镜眼镜可能改善其功能性视力和日常生活活动。这些扇形棱镜——连同适当的训练——可能通过更有效的视觉扫描技能增强周边感知。
