Aqueous humor glycation marker and plasma homocysteine in macular degeneration.

Background: We investigated concentrations of total homocysteine (tHcy) in elderly people without and those with age-related macular degeneration (AMD). In addition, we tested the association between plasma tHcy and one glycation marker in aqueous humor.

Methods: People with cataract only (n=48), patients with dry AMD (n=38) and those with wet AMD (n=31) were studied.
