To report an increased functional visual acuity, which was recently reported as a simulation of visual function of daily acts of gazing, in dry eye patients after punctal occlusion.
Prospective comparative interventional study.
We measured ordinary best-corrected visual acuity and functional visual acuity in eight eyes of eight dry eye patients after punctal occlusion, and compared the results with those of 22 eyes of 22 dry eye patients without punctal occlusion.
Functional visual acuity in dry eye patients after punctal occlusion was 0.962 in decimal notation, which was significantly higher than that of patients without punctal occlusion, 0.283 (P <.0001).
This study shows that punctal occlusion can improve the impaired functional visual acuity of dry eye patients.
报告泪点封闭术后干眼患者功能性视力提高的情况，近期该情况被报道为模拟日常注视行为的视觉功能。
前瞻性对比干预性研究。
我们测量了8例干眼患者泪点封闭术后8只眼的常规最佳矫正视力和功能性视力，并将结果与22例未行泪点封闭的干眼患者的22只眼进行比较。
泪点封闭术后干眼患者的功能性视力以小数表示为0.962，显著高于未行泪点封闭患者的0.283（P <.0001）。
本研究表明，泪点封闭可改善干眼患者受损的功能性视力。
