Association between blood lipid level and primary open angle glaucoma / 中华检验医学杂志

ABSTRACT

Objective To explore the relationship between blood lipid level and primary open angle glaucoma(POAG)and intraocular pressure(IOP).Methods A retrospective case-control study was designed.80 POAG patients from EYE & ENT hospital of FUDAN university were collected as a case group from January 2015 to May 2016.Meanwhile 80 age and gender matched healthy people were collected as a control group.The differences of gender in men subgroup (POAG44,Control39) and female subgroup (POAG36,Control41) showed no statistic significance.Serum total cholesterol(TC),total triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),apolipoprotein A(Apo A) and apolipoprotein B(Apo B) were measured using Roche automatic biochemical analyzer.The analysis of the above mentioned lipid levels between POAG group and control group was conducted by independent student′s T test and multivariate logistic regression.The relationship between lipid level and IOP was analysied using Pearson correlation test.Results The TG level was (1.40±0.71)mmol/L in the POAG group,(1.00±0.37)mmol/L in the control group.The difference had statistic significance (t=4.467,P<0.001).The HDL-C level in the POAG group was (1.22±0.36)mmol/L,(1.38±0.25)mmol/L in the control group.The difference also had statistic significance (t=-3.228,P=0.002).Comparison between the men subgroup and female subgroup found that the TG level in the POAG group of men was (1.47±0.71)mmol/L,(1.01±0.36) mmol/L in the control group and the HDL-C level were (1.14±0.31) mmol/L,(1.32±0.20)mmol/L in two groups.Both the level of TG and HDL-C had statistic significance in men (t=3.717,P<0.001;t=-3.240,P=0.002).The TC,TG level in the POAG group and control group of women respectively were (4.59±0.81)mmol/L,(1.33±0.72)mmol/L and (4.21±0.64)mmol/L,(0.99±0.38)mmol/L.Both blood level were significantly higher than the control group in women (t=2.278,P=0.026;t=2.503,P=0.016).Logistic regression analysis showed that the TG level correlated with POAG (P=0.004,OR=2.831,95% CI=1.392-5.759)and both POAG in the men and women (P=0.025,OR=3.223,95% CI=1.156-8.989;P=0.045,OR=2.554,95% CI=1.020-6.395).Pearson test showed that the TG level of POAG patients was positively associated with IOP in spite of gender(P<0.05).Conclusion The peripheral blood level of TG was significantly increased in the POAG patients and significantly correlated with IOP,which indicated that the increased peripheral blood level of TG may be the independent risk factor for the POAG..
