【 摘 要 】

PURPOSE: To analyze the difference between measurements of Schirmer test I (ST I) and basal Schirmer test (STB) with open and closed eyes. METHODS: Sixty eyes of 30 normal volunteers, 12 males and 18 females aged 28 ± 9 years were recruited for the study. All ST were carried out in a closed environment with the absence of airflow (humidity 60 ± 2.34% and temperature 20.72 ± 1.52ºC). ST I and ST B were performed with the individuals' both eyes open and closed with an interval of 6 hours. All ST were conducted in 5 minutes. For statistical analysis, the ST strip's wetting velocity (ST V) (in millimeters per minute) was calculated, dividing the ST values by its wetting time. If ST values were 35mm before 5 minutes, wetting time was recorded to obtain ST V. RESULTS: ST V measurements of ST I performed with closed eyes (10.30 ± 11.55) were statistically different from those performed with open eyes (18.85 ± 17.88) and ST V measurements of STB performed with closed eyes (3.74 ± 3.14) were statistically different from those performed with open eyes (6.19 ± 5.86). CONCLUSION: ST performed with open or closed eyes can have an important influence in the results of ST I and STB in normal individuals.
