Lipoproteins in human subretinal fluids

Abstract

The lipids in the subretinal fluid of rhegmatogenous retinal detachment are observed mainly in the albumin position following electrophoresis on agarose film. The lipoprotein in the subchoroidal fluid of the same eye is alpha-lipoprotein. The albumin-like lipoprotein in subretinal fluid has no reaction with the antiserum samples specific to alpha-lipoprotein and beta-lipoprotein. Instead, an apoprotein of serum alpha-lipoprotein with slow electrophoretic mobility was observed in subretinal fluid. Heterogeneous degradation products of serum lipoproteins were seen in the subretinal fluid of exudative retinitis, different from the subretinal fluid of rhegmatogenous retinal detachment and uveal effusion.
