Serum patterns for two exemplary PUFAs for patients with retinal disease and controls. Top row shows serum levels of docosahexaenoic acid (DHA, 22:6), an omega-3 fatty acid, bottom row shows the same for arachidonic acid (AA, 20:4), an omega-6 fatty acid. In this analysis, patients with diabetic retinopathy (DR), retinal vein occlusion (RVO) and age-related macular degeneration (AMD) were subdivided into their respective subgroups as indicated. No significant differences were detected across groups. The same is true for all other PUFAs investigated (not shown). Mean and standard deviations of relative fatty acid compositions (all lipid classes) are given
