To evaluate the effect of the iPad as a low vision aid in improving the reading ability of low vision patients (LVPs).
In this study, 228 consecutive patients that came for their routine eye care examination at the University of Florida, Jacksonville eye clinic, were enrolled. Patients met inclusion criteria if they had best-corrected visual acuity (BCVA) of 20/100 or worse in the best corrected eye and were willing to participate in the study. The patient's reading ability was assessed both with the patient's own spectacles and an iPad. Patients were encouraged to enlarge the reading material as well as change the contrast until they could read comfortably. The number of patients able to read the text comfortably was recorded.
Out of the total 228 participants who qualified, 103 (45%) were male and 125 (55%) were female. Only 22% could read standard newsprint-sized text (N8) without the help of an iPad. With the help of an iPad, 94% participants with impaired vision were able to read standard newsprint-sized text (N8) or smaller text (P<0.01).
The iPad, a new portable electronic media device, can be adapted by LVPs to improve their reading ability.
评估iPad作为低视力辅助工具对提高低视力患者（LVP）阅读能力的效果。
在本研究中，招募了228名连续前往佛罗里达大学杰克逊维尔眼科诊所进行常规眼部护理检查的患者。如果患者最佳矫正眼的最佳矫正视力（BCVA）为20/100或更差，且愿意参与研究，则符合纳入标准。使用患者自己的眼镜和iPad对患者的阅读能力进行评估。鼓励患者放大阅读材料并改变对比度，直到他们能够舒适地阅读。记录能够舒适阅读文本的患者人数。
在符合条件的228名参与者中，103名（45%）为男性，125名（55%）为女性。只有22%的人在没有iPad帮助的情况下能够阅读标准报纸大小的文本（N8）。在iPad的帮助下，94%的视力受损参与者能够阅读标准报纸大小的文本（N8）或更小的文本（P<0.01）。
iPad是一种新型便携式电子媒体设备，低视力患者可以使用它来提高阅读能力。
