The LIFE-Adult study also suggests categorizing adverse lipid profiles (e.g., high apolipoprotein B (ApoB), high non-HDL cholesterol, high total cholesterol, high low-density lipoprotein (LDL) cholesterol, low high-density lipoprotein (HDL) cholesterol) as independent covariates of thicker cpRNFLT, thus helping conceal nerve fiber decay in glaucoma, of which per 1 mmol/l increase in non-HDL cholesterol brings about 0.5 μm elevation in cpRNFLT [20]. Here, APOB is linked to glaucoma.
