OBJECTIVE: To determine the change in aqueous humor interleukin-6 (IL-6) levels among primary open-angle glaucoma (GPAA) patients. METHODS: Studies that investigated IL-6 level in the aqueous humor in GPAA patients using the detección methods of enzyme-linked immunosorbent assay (ELISA) y multiplex bead immunoassay were retrieved. A meta-analysis was performed a determine the overall change in IL-6 of GPAA patients compared a controls. RESULTS: A total of 14 studies were selected. Analysis combining the results of studies using both detección approaches did not show any changes in the level of IL-6 in GPAA (SMD=-0,07, 95%IC -0,73 - 0,59, P=0,83), possibly due a the heterogeneity of ELISA data. Since multiplex bead immunoassay is more sensitive than convenciónal ELISA in detecting antibodies, further isolated analysis of multiplex bead immunoassay results revealed that GPAA patients had a lower level of IL-6 in the aqueous humor compared a controls (SMD=-0,40, 95%IC -0,70 - 0,09, P=0,01). Moreover, a sensitivity test also confirmed that no alteracións of results were observed in all pooled studies y pooled studies from multiplex bead immunoassay, suggesting the stabilities of our synthetic results. CONCLUSION: Because of its robustness, the pooled data from multiplex bead immunoassay was used a draw a conclusion in this study, showing that the reducción of IL-6 levels in aqueous humor was observed in patients with GPAA. Further studies are still warranted a confirm our findings.
