Dyslipidemia, Dyslipidemia Treatment, and Open-angle Glaucoma in the Korean National Health and Nutrition Examination Survey.

PURPOSE

The purpose of this study was to investigate the association between dyslipidemia treatment and open-angle glaucoma (OAG).

PATIENTS AND METHODS

We included 16,939 participants aged ≥40 years from the Korea National Health and Nutrition Examination Survey (2008 to 2012) and classified them into 2 groups based on current dyslipidemia treatment. The prevalence of OAG was determined using the modified International Society of Geographical and Epidemiological Ophthalmology criteria. The association between dyslipidemia treatment and OAG was evaluated using logistic mixed-effects model and propensity-score-weighted odds ratios.

RESULTS

Analyses using the 2 abovementioned models revealed that dyslipidemia treatment was not associated with OAG (odds ratio, 1.08; 95% confidence interval, 0.75-1.56; P=0.838 and 1.03; 0.71-1.48; P=0.882, respectively), presence of optic disc hemorrhage (0.64; 0.15-2.73; P=0.648 and 1.10; 0.39-3.11; P=0.855), high vertical cup-to-disc ratio or asymmetry (1.02; 0.81-1.28; P=0.736 and 0.95; 0.75-1.20; P=0.650), presence of retinal nerve fiber layer defects (0.97; 0.67-1.42; P=0.857 and 1.03; 0.75-1.42; P=0.857), and presence of visual field defects (0.93; 0.55-1.54; P=0.931 and 0.97; 0.81-1.52; P=0.528). Total cholesterol and high-density lipoprotein cholesterol were also not associated with OAG. However, higher serum triglyceride levels were associated with OAG in the treated patients (1.31; 1.02-1.68; P=0.027) but not in the untreated patients (1.03; 0.93-1.14; P=0.079).

CONCLUSIONS

In the Korean population, dyslipidemia treatment was not significantly associated with open-angle glaucoma. However, hypertriglyceridemia was associated with OAG in treated patients.
