To evaluate the efficacy of a new continuous functional visual acuity measurement (FVAM) system for the assessment of dry eye patients.
Prospective comparative study.
Monocular recognition acuity measured continuously by the FVAM system during a 30-second blink-free period was defined as functional visual acuity (FVA). Examinations using the FVAM system were conducted in 35 eyes of 20 healthy controls and 19 eyes of 13 dry eye patients. Tear function examinations including the Schirmer test, tear film break-up time, and fluorescein and Rose Bengal staining were performed in all subjects. Functional visual acuity and tear functions were also examined before and after insertion of punctum plugs in dry eye patients. Functional visual acuity results at 10, 20, and 30 seconds were compared.
Functional visual acuity in dry eyes were significantly lower than control subjects at all time points (P < .05). Functional visual acuity after punctum plugs insertion improved significantly at all time points (P < .05).
FVAM system seemed not only to be an effective tool in the assessment of dynamic visual acuity changes in dry eye and normal subjects but in evaluating the outcome of management of dry eye disease by punctum plugs.
评估一种新型连续功能性视力测量（FVAM）系统用于评估干眼患者的疗效。
前瞻性对照研究。
在30秒无眨眼期间通过FVAM系统连续测量的单眼识别视力被定义为功能性视力（FVA）。对20名健康对照者的35只眼和13名干眼患者的19只眼进行了FVAM系统检查。对所有受试者进行了包括泪液分泌试验、泪膜破裂时间以及荧光素和孟加拉玫瑰红染色在内的泪液功能检查。还对干眼患者在插入泪小点栓子前后进行了功能性视力和泪液功能检查。比较了10秒、20秒和30秒时的功能性视力结果。
在所有时间点，干眼患者的功能性视力均显著低于对照受试者（P < 0.05）。插入泪小点栓子后，在所有时间点功能性视力均显著改善（P < 0.05）。
FVAM系统似乎不仅是评估干眼和正常受试者动态视力变化的有效工具，而且还可用于评估泪小点栓子治疗干眼疾病的效果。
