APOA1 and snowflake vitreoretinal degeneration: Compared with the ND group, the expression of ALP (p = 0.008) in the SVD subgroup was increased, while the expression of HDL-C (p = 0.032) was decreased; the expression of hs-CRP (p = 0.026) in the PVD subgroup was increased, while APOA1 levels were decreased in both the SVD (p = 0.003) and PVD (p = 0.043) subgroups.
