Abstract

Purpose: There is limited evidence to evaluate the numerical cutoff point for detecting early presbyopia. Thus, we aimed to establish a clinically relevant optimal cutoff value of near visual acuity for detecting early presbyopia.

Study design: Prospective diagnostic accuracy study.

Methods: We included consecutive individuals aged ≥ 20 years with a binocular-corrected distance visual acuity of ≥ 20/25 who did not undergo ophthalmic surgery between December 17, 2020 and December 19, 2021, at two healthcare facilities in Japan. Binocular distance-corrected near visual acuity at 40 cm, accommodative amplitude, awareness of presbyopia, and Near Activity Visual Questionnaire scores were examined. The optimal cutoff values of distance-corrected near visual acuity for diagnosing early presbyopia were evaluated using receiver operating characteristic plots.

Results: Among 115 participants, 74 (64.3%) had presbyopia. The proportion of participants with no difficulty performing near-vision tasks decreased markedly when near visual acuity decreased to 20/20 (> 0.00 logMAR). A cutoff value of 0.00 logMAR for distance-corrected near visual acuity was optimal, showing high sensitivity of 56.76% and specificity of 92.68%, as opposed to the commonly used cutoff value of 0.40 logMAR (20/50; sensitivity, 9.46% and specificity, 100%) for diagnosing early presbyopia.

Conclusion: Near visual acuity of 0.00 logMAR (20/20) could be the optimal cutoff value for diagnosing early presbyopia.

确定评估早期老花眼的近视力临界值。
目的:评估检测早期老花眼的数值临界点的证据有限。因此,我们旨在确定一个与临床相关的、用于检测早期老花眼的最佳近视力临界值:研究设计:前瞻性诊断准确性研究:我们纳入了2020年12月17日至2021年12月19日期间在日本两家医疗机构连续就诊的年龄≥20岁、双眼矫正远视力≥20/25且未接受眼科手术的患者。研究考察了 40 厘米处的双眼远距离校正近视力、容纳幅度、对老花眼的认识以及近距离活动视觉问卷评分。使用接收器操作特征图评估了用于诊断早期老花眼的距离校正近视力的最佳临界值:115 名参与者中有 74 人(64.3%)患有老花眼。当近视力下降到 20/20(> 0.00 logMAR)时,执行近视任务没有困难的参与者比例明显下降。与诊断早期老花眼常用的 0.40 logMAR 临界值(20/50;灵敏度为 9.46%,特异度为 100%)相比,0.00 logMAR 临界值是最佳的远距离校正近视力,其灵敏度高达 56.76%,特异度高达 92.68%:结论:0.00 logMAR(20/20)的近视力可能是诊断早期老花眼的最佳临界值。

期刊介绍: The Japanese Journal of Ophthalmology (JJO) was inaugurated in 1957 as a quarterly journal published in English by the Ophthalmology Department of the University of Tokyo, with the aim of disseminating the achievements of Japanese ophthalmologists worldwide. JJO remains the only Japanese ophthalmology journal published in English. In 1997, the Japanese Ophthalmological Society assumed the responsibility for publishing the Japanese Journal of Ophthalmology as its official English-language publication. Currently the journal is published bimonthly and accepts papers from authors worldwide. JJO has become an international interdisciplinary forum for the publication of basic science and clinical research papers.
