목적 : To investigate the relationship between peripapillary vessel density (VD) and anterior segment structures in acute (APACG) and chronic primary angle closure glaucoma (CPACG) eyes.
방법 : Twenty nine APACG eyes and 38 CPACG were enrolled. The peripaillary VD was obtained using optical coherence tomography angiography (OCTA, AngioVue/RTVue-XR) and anterior chamber angle parameters were assessed by anterior segment (AS) OCT (Visante). Linear regression model was used to evaluate the relationship between peripapillary VD and AS-OCT parameters in APACG and CPACG eyes, respectively.
결과 : The peripapillary retinal vessel density tended to be lower in the APACG eyes than in theCPACG eyes, but the difference was not statistically significant (42.62 ± 9.72% versus 44.30 ± 9.02%; p=0.469). In linear regression analysis, lower RNFL thickness (r=0.217, r=0.139, respectively; p<0.001, p=0.005) showed significant correlation with reduced peripapillary VD in both groups. In APACG eyes, higher visual field (VF) pattern standard deviation (r=-0.806; p=0.007) was associated with reduced peripapillary VD, while in CPACG eyes, lower VF mean deviation (r=0.355; p<0.049) showed association.
결론 : Peripapillary VD showed significant association with glaucoma severity in both APACG and CPACG eyes.
