ABSTRACT Purpose The present study measured 41 soluble mediators in the tear of 19 patients with age-related cataract and 32 healthy adults as controls. Materials and Methods This was a prospective, case–control study in which, using multiple immunoassays, we measured in tear samples the following molecules: EGF, FGF-2, Eotaxin, TGF-α, G-CSF, Flt-3L, GM-CSF, Fractalkine, IFN-α2, IFN-γ, GRO, IL-10, MCP-3, IL-12p40, MDC, IL-12p70, PDGF-AA, IL-13, PDGF-AB/BB, IL-15, sCD40L, IL-17a, IL-1ra, IL-1α, IL-9, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IP-10, MCP-1, MIP-1α, MIP-1β, RANTES, TNFα, TNFβ, VEGF. Statistical analyses were done by multiple adjusted models and p values were corrected by the Benjamini and Hochberg method. Results We did not find significant differences in the amount of the tested molecules in the tear fluid between cataract patients and controls. Correlation analyses relative to age were carried out for both groups. Analysis of MCP-1 tear levels revealed a direct correlation with age for normal healthy controls as well as for cataract patients. But IL-6 tear levels correlated with age only in the group of cataract patients. In addition, IL1-ra tear levels correlated with cataract nuclear grade; higher grades were associated with higher IL-1ra concentrations. Conclusions Our results suggest that ocular aging is accompanied by increased production of IL-6 and MCP-1, which can be measured in tear fluid.
