摘要
目的探讨结膜松弛症对泪液学的影响。方法结膜松弛症与对照组各20例(40眼)进行SchirmerⅠ试验、基础Schirmer试验、泪河测量、BUT、荧光素活体染色。结果 SchirmerⅠ试验和基础Schirmer试验中结膜松弛症组与对照组比较,差异无显著意义,P>0.05。但基础Schirmer试验≤5mm者,结膜松弛症14眼(35.0%)与对照组5眼(12.5%)比较,差异有显著意义(P<0.05)。泪河异常结膜松弛症(80.0%)较对照组(30.0%)多,差异有显著意义(P<0.01)。结膜松弛症组与对照组BUT比较,差异有显著意义(P<0.01)。荧光素活体染色:结膜松弛症组异常者23眼(63.8%)与对照组异常者14眼(38.8%)比较,差异有显著意义(P<0.05)。结论结膜松弛症泪液分泌异常,泪膜稳定性下降、泪液排泄延缓。
Purpose To investigate the effect of conjunctivochalasis on lacrimal fluid system. Methods 20 cases (40 eye) of conjunctivochalasis and control group, were observed respectively for Schirmer 1 test, basal Shirmer test, tear meniscus, tear break up time( UBT), and fluorescein staining of ocular surface. The result were analyzed statistically. Results The Schirmer test had no statistical significance (P > 0.05), but in basal Shirmer test scores were lower in conjunctivochalasis group. Tear meniscus had significant differences( P < 0.05) between conjunctivochalasis group and control group. BUT scores were significantly lower in conjunctivochalasis group compared with the control group. Conclusion The redundant bulbar conjunctival tissue can lead to the decrease of both the quantity of quality of tear secration and thus cause the instability of tear film and the obstruction of the excretory part of the lacrimal system.
