目的 :评估结膜松弛症对泪液排泄系统的影响。方法 :结膜松弛症与对照组各 8例 (16只眼 ) ,在SPECT下 ,用99mmTcO-4 动态显像 ,比较结膜松弛症组与对照组T1/2值和结膜松弛症组手术前后的T1/2值。结果 :结膜松弛症组T1/2值(2 92± 198)明显大于对照组 (110± 38) ,差异有显著性意义 (t=3 5 8,P <0 0 1)。结膜松弛症组手术后T1/2值 (2 45± 115 )较手术前明显缩短 (35 6± 189) ,差异具有显著性意义 (t=3 18,P <0 0 1)。手术切除松弛结膜后解除了对泪液排泄系统的影响 ,患者的溢泪症状改善。结论 :结膜松弛症中泪液排泄系统功能不全 ,泪液排泄延缓
OBJECTIVE: To assess the effects of conjunctivochalasis on tear drainage system. Methods: Conjunctivochalasis and control group, 8 cases (16 eyes), SPECT with 99mmTcO-4 dynamic imaging, conjunctivochalasis and control group T1 / 2 values and conjunctivochalasis before and after surgery T1 / 2 value. Results: The T1 / 2 value of conjunctivochalasis group (2 92 ± 198) was significantly higher than that of the control group (110 ± 38), the difference was significant (t = 358, P <0.01). The T1 / 2 value of conjunctivochalasis group (2 45 ± 115) was significantly shorter than that before operation (35 6 ± 189), the difference was significant (t = 3 18, P 0 01). Surgical removal of loose conjunctiva after lifting the tear drainage system, the patient’s symptoms of overflowing tears improved. Conclusion: The lacrimal discharge system in conjunctivochalasis is dysfunctional and lacrimal fluid excretion is delayed
