Abstract | PURPOSE: METHODS: Sixteen consecutive patients with unilateral CRVO and macular oedema were studied, along with eight age- and sex-matched patients without ischaemic ocular disease. Retinal ischaemia was evaluated from capillary non-perfusion on fluorescein angiography. Macular oedema was examined by optical coherence tomography. Aqueous humour (AH) samples were obtained during combined pars plana vitrectomy and cataract surgery, and were examined by enzyme-linked immunosorbent assay. RESULTS: Aqueous levels of VEGF and IL-6 were significantly elevated in patients compared with controls (p=0.0142 and p<0.0001, respectively). Aqueous levels of both molecules were significantly higher in patients with ischaemia than in those without ischaemia (p=0.0026 and p=0.0487, respectively). Furthermore, AH levels of VEGF and IL-6 were correlated with the severity of macular oedema (ρ=0.7265, p=0.0049, ρ=0.5324, and p=0.0392, respectively). CONCLUSIONS: Both VEGF and IL-6 were elevated in the AH of patients with macular oedema and ischaemic CRVO, suggesting that these molecules may be related to the increase in vascular permeability in such patients.
