Our results show that the leukocyte populations in the ARMD are dominated either by macrophages or by T-lymphocytes but the percentage of the polymorphonuclear leukocytes (i.e. CD15 positive cells including both neutrophils and eosinophils) remained rather low, the median being less than 2% of all leukocytes. Here, FUT4 is linked to age-related macular degeneration.
