Abstract

Purpose: To test an alternative method of visual acuity assessment by comparing habitual and best-corrected visual acuity by Snellen and Peek (a visual acuity testing smartphone application). Methods: A prospective study comparing visual acuity using Snellen's and Peek's visual acuity charts (smartphone-based applications). 162 eyes were assessed in this hospital-based setting by a single observer. Patients with gross ocular pathology and visual acuity less than 6/60 were excluded from the study. Results: There was no statistically significant difference between best corrected visual acuity by Snellens and Peeks'. Snellen's mean best corrected visual acuity was 0.9902 (±0.075), and Peek acuity was 0.9875 (±0.080). Conclusion: The visual acuity assessment by Peek is comparable to that of Snellen's; hence, it can be used as an excellent alternative to Snellens' visual acuity testing.
基于智能手机的窥视视力与斯奈伦视力的比较
目的:通过比较斯奈伦法和 Peek(视力测试智能手机应用程序)的习惯视力和最佳矫正视力,测试视力评估的替代方法。研究方法一项前瞻性研究,比较使用斯奈伦视力表和 Peek 视力表(基于智能手机的应用程序)的视力。在医院环境中,由一名观察者对 162 只眼睛进行了评估。患有严重眼部病变且视力低于 6/60 的患者不在研究范围内。研究结果斯氏最佳矫正视力和皮克斯最佳矫正视力之间没有明显的统计学差异。斯氏最佳矫正视力的平均值为 0.9902(±0.075),皮克视力为 0.9875(±0.080)。结论Peek 的视力评估结果与斯奈伦视力评估结果相当,因此可作为斯奈伦视力测试的最佳替代方法。
