“…Several antidiabetic compounds have shown potential for glaucoma treatment (Lin et al, 2015;Maleškić et al, 2017;Sterling et al, 2021) (Table 3). In support of this, several studies have suggested that diabetes mellitus is a risk factor for glaucoma (Oshitari et al, 2007;Chopra et al, 2008;Welinder et al, 2009;Zhou et al, 2014;Horwitz et al, 2016;Jung et al, 2018;Hanyuda et al, 2020). Thus, it raises the question of whether glaucoma may be associated with retinal insulin desensitization (Agostinone et al, 2018) as well as insulin desensitization of the brain as associated with Alzheimer's and Parkinson's disease (Faiq et al, 2014;Dada, 2017;Faiq and Dada, 2017).…”
