Abstract

Five methods of testing tears including the Schirmer tear test (STT-1), phenol red thread tear test (PRT) and modified Schirmer tear test (STT-2) were conducted on 44 eyes of 22 normal Beagles, and the tear film break up time (BUT) and lacrimal pH were tested in 32 eyes of 16 normal Beagles. The coefficient of variation of PRT demonstrated a low value (C.V. 12%) [corrected] compared to the value of STT-1 (C.V. 14%) [corrected]. The lacrimal pH showed a more constant value (C.V. 3%). Measurements of STT-2 (C.V. 48%) and BUT (C.V. 34%) varied significantly. The results show the clinical usefulness of the PRT. Mean values (mean +/- SD) of tests were: PRT, 29.3 +/- 3.45 mm/15 s; STT-1, 18.89 +/- 2.62 mm/60 s; STT-2, 9.52 +/- 4.55 mm/60 s; pH, 7.29 +/- 0.22 and BUT, 21.53 +/- 7.42 s.

摘要

对22只正常比格犬的44只眼睛进行了五种泪液测试方法，包括泪液分泌试验（STT-1）、酚红棉线泪液试验（PRT）和改良泪液分泌试验（STT-2），并对16只正常比格犬的32只眼睛测试了泪膜破裂时间（BUT）和泪液pH值。与STT-1（变异系数14%[校正后]）相比，PRT的变异系数显示出较低的值（变异系数12%[校正后]）。泪液pH值显示出更稳定的值（变异系数3%）。STT-2（变异系数48%）和BUT（变异系数34%）的测量值差异显著。结果显示了PRT的临床实用性。各项测试的平均值（均值±标准差）为：PRT，29.3±3.45毫米/15秒；STT-1，18.89±2.62毫米/60秒；STT-2，9.52±4.55毫米/60秒；pH值，7.29±0.22，BUT，21.53±7.42秒。
