Studies on the key proteins associated with glaucoma have also provided new perspectives in finding potential therapeutic targets, such as myocilin (MYOC), latent transforming growth factor‐beta‐binding protein 2 (LTBP2), optineurin (OPTN), TANK‐binding kinase 1 (TBK1) and other genes implicated in inherited forms of glaucoma.15, 16. Here, OPTN is linked to glaucoma.
