We determined the relationship between the serum levels of total IgG and related subclasses and the retinic vascular injuries observed in a 44 males, drug addict group, 12 HIV-negative and 32 HIV-positive. The only correlation is that between the increase of the IgG (subclasses IgG1 and IgG3) and serum-positivity to HIV; while no relationship is shown between the concentrations of the observed immunoglobulinic subclasses and the possibly observable retinic vascular damage.
