對一般眼科門診時常遭遇到的主訴流淚的患者,應如何以簡便有效的方法測試?本篇收集無症狀的三十人(六十眼)施以Jones Dye Test與Fluorescein Dye Disappearance Test評量它們的可行性,正確性及彼此的關聯。Jones Ⅰ染料試驗的陽性率可達86.7%,然而Fluorescein Dye Disappearance Test的陽性率卻高達95.3%,前者有直接證據但是後者卻屬間接觀察,但兩者皆不失為評估排淚功能簡易而有效的方法。
We Studied 30 randomly selected individuals without epiphora. Jones dye test and Fluorescein dye disappearance test (FDDT) were performed and evaluated. Among 60 eyes, only 1 eye (1.7%) was regarded as negative in FDDT while 8 eyes (13.3%) were negative in Jones Ⅰ dye test. However, none was negative in Jones Ⅱ test. We also concluded that Subjects whose Basal Secretion test values are over 10mm/5min have Statisticably higher positive rate in Jones Ⅰ test than those under l0min/5min. The Study suggests that Jones Ⅰ test remains the most important screening test for assessment of lacrimal excretion, however, FDDT can be given as an adjunct for its high sensitivity and rapid interpretation.
