Studies comparing the levels of fibronectin in aqueous humor found in patients with cataracts to that of glaucoma patients showed that the levels of fibronectin were nearly sevenfold higher in glaucomatous patients (0.136 ± 0.192 μg/mL vs. 0.962 ± 0.918 μg/mL, respectively) [14,15]. This evidence concerns the gene FN1 and cataract.
